CIS 336 Week 1 iLab 1 Devry University
L A B O V E R V I E W Scenario/Summary This lab will introduce you
to the processes involved in defining one of the key components of a
data model; the relationship diagram (RD). In this lab, you will draw a
relationship diagram for two of the steps shown. Keep in mind when you

are trying to decide which side of the relationship should be the "one"
side and which should be the "many" that you must first decide which
side has the primary key, or unique identifier. Once you have decided
the primary key of the relationship, you have identified the "one" side of
the relationship. Note that for an RD, the foreign key "many" side of the
relationship points to the primary key "one" side. The "one" side should
have the arrowhead point of the connecting line. This is different than an
entity/relationship diagram (ERD) that we will draw next week, where
the "many" side has crow's feet. This will familiarize you with how to
set up MS Visio to draw database diagrams. Steps 1 - 3 below use the
Customer, Order, and Employee tables of a simplified Order Entry
database. The Customer table records clients who have placed orders.
The Order table contains the basic facts about customer orders. The
Employee table contains facts about employees who take orders. The
primary keys of the tables are CustNo for Customer, EmpNo for
Employee, and OrdNo for Order. The following are the TABLE
definitions for the first three tables showing the PRIMARY KEY
constraints. TABLE Customer has the following attributes CustNo
NUMBER(5) CustFirstName VARCHAR2(20) CustLastName
VARCHAR2(30) CustCity VARCHAR2(30) CustState CHAR(2)
CustZip CHAR(10) CustBal NUMBER(12,2) CustNo is the PRIMARY
KEY TABLE Employee has the following attributes EmpNo
NUMBER(5) EmpFirstName VARCHAR2(20) EmpLastName
VARCHAR2(30) EmpPhone CHAR(15) EmpNo is the PRIMARY KEY
TABLE Order has the following attributes OrdNo NUMBER(5)
OrdDate DATE CustNo NUMBER(5) EmpNo NUMBER(5) OrdNo is
the PRIMARY KEY Your task for this lab is to create the required
relationship diagram for steps 1 and 2 using Microsoft Visio. Step 3 will
require you to analyze the scenario given and present your own
resolution to the question. Step 4 is an individual assignment that will

introduce you to the group project and the process of identifying entities
and attributes. When finished with the lab, you should have a complete
diagram using all 5 entities, a written explanation for #3, and two lists
(entities and attributes) for Step 4. Deliverables The deliverable for this
lab is a single MS Word document named "Lab1_solution_yourname"
with the diagram for problems 1 and 2, the written answer for the
question in Step 3, and the lists of entities and attributes for the Initial
Project Exercise (Step 4). You should copy and paste the diagram from
MS Visio into a Word document and use this document for Steps 3 and
4. L A B S T E P S STEP 1: Drawing your first ER diagram Title
Identify the foreign key columns in the table structures above and draw a
relationship diagram depicting the relationships between the tables. In
the Order table , the CustNo column references the Customer table and
the EmpNo column references the Employee table. For each
relationship, identify the table on the "1" side of the relationship and the
table on the "Many" side. STEP 2: Extending the ER diagram Extend
your relationship diagram from problem 1 by adding two tables
(OrdLine and Product). Table definitions for the table structures and
primary keys constraints are shown below. You will need to identify the
FOREIGN KEY(s) to complete this problem. When finished you should
have a total of 5 tables represented in your diagram for this problem. To
copy and paste the diagram into Word, select Edit from the menu and
then Copy Diagram. Open a Word document and use CTRL-V to paste
the diagram. TABLE Product has the following attributes ProdNo
CHAR(8) ProdName VARCHAR2(20) ProdNo is the PRIMARY KEY
TABLE OrdLine has the following attributes OrdNo CHAR(8) ProdNo
CHAR(8) Qty NUMBER(5) The combination of OrdNo and Prodno is
the PRIMARY KEY STEP 3: Should a NULL be allowed? From
examination of the sample data and your current understanding of
businesses in which orders could be placed either in person, over the

phone, or over the Internet, determine if it would be permissible for null
values to be allowed for the foreign key EmpNo in the Order table. This
column would reference back to the EmpNo column in the employee
table. Why or why not? OrdNoOrdDateCustNoEmpNo O1656777

STEP 4: Initial Project Exercise Although the overall project itself will
be done as a group, this first exercise is designed as an individual effort
and is intended to; (1) get you to read the project specifications, and; (2)
introduce you to the first step in designing a database from scratch. This
little exercise will have you see how many entities and attributes you can
find in the project specifications. In week three, you will work with your
assigned project team and compare notes on what you have found. This
is not rocket science here so remember, you are looking for people,
places, things, and events (entities) and the attributes that describe them.
---------------------------------------------------------------
Lab two introduces the next step in creating a data model, the Entity
Relationship Diagram (ERD). You will be given a business scenario for
a company named Clapham Specialty Store, which is a small specialist
grocery and delicatessen. The business specifications will outline a
number of things about the business, some of which will apply directly
to the database you are being asked to model. There is a table which lists

the entities (tables) that will be needed for the database and related
attributes (columns) for each entity. There is also a column that lists
specific information about the entity that will be helpful in determining
its relationship to other entities within the model. Be sure to include the
minimum and maximum occurrences of each relationship (cardinality)
and to supply a name to the relationship that will work in both
directions. If there is not a single word that will apply, then supply a
separate name for each direction of the relationship. Narrative/Case
Study The Clapham Specialty Store is a small, specialist grocery and
delicatessen. A new owner, John Balfour, who would like to expand the
store and improve its profits, has recently purchased the store. The store
sells general groceries, wines and liquors, and has a small deli counter.
The store is open from 5:00 a.m. to 12:00 midnight. Many of the
customers are repeat customers who come in to buy products they forgot
from their regular grocery shopping expedition at the supermarket. The
store sells about 3,000 different products ranging from toilet cleaner to 2
oz. jars of caviar, and champagne to liverwurst. Each product is
displayed on a shelf on one side or the other of the aisle. The products
arrive and their details (cost, quantity, SKU number, package size,
purchase date) are recorded in the back room before they are displayed.
The new owner wants to know which products the store sells most of
and which are the most profitable. The following is some general
information about the company and its current processes. The store has 3
cash registers. Between 3 and 7 employees will work at any given time,
depending on the time of day and how busy they are. An employee logs
in to the register at the start of a shift and logs out at the end. The name,
address, Social Security number and other information is recorded for
every employee. All employees are paid weekly against an hourly rate
which varies depending on their job description. Each sale is identified
by a Receipt No. and a timestamp (date and time) and consists of sale

items with a quantity and price recorded for each product. As a
convenience for known customers, they offer a local delivery service.
Deliveries are only made to customers who are registered at the store;
walk-ins must record their name, address, and phone number before a
delivery can be made to them. John can find the cost of the goods from
the accounts system. What John would like to have is a point of sale
system (POS) that records what has been sold to whom, by whom, for
how much, and when. Also, he needs to be able to record the delivery
trips that are made, who makes the delivery, how long the delivery takes,
and the amount of the sale. There is concern at this point that the cost of
delivering the sales to customers is not worth the return on investment.
Requirements: You have been asked to develop a logical data model for
Clapham Specialty Store based on the information given to you by John
and his staff. Through analysis of the nouns and verbs in the case study
above, you have accumulated the following entity, attribute, and
relationship information shown in the table below. The attribute list may
not be complete. If you determine that additional attributes are needed to
better define an entity then you should add them. Entities Attributes and
Relationships for Clapham Store: Entity Attributes Relationships
Employee ID Number, Last Name, First Name, Phone Number,
Employee Type ID An Employee can belong to any one of the three job
categories, but can belong to one and only one of the three. Employees
have names and other contact information. Employee Type Type ID,
Description, Hourly Pay Rate An employee can be either a clerk,
delivery person, or a supervisor. Register Log Register Log Number,
Register Number, Log In Time, Log Out Time, Employee ID Sales are
made using a register and can be tracked by the register log number. An
employee must log into the register before he/she can use it and must log
out when finished with a shift at that register. An employee may use
more than one register during a period of work. Register Register

Number, Register Location Description, Register Serial Number The
store has 3 registers: One located at the back of the store and two located
at the front of the store; one on the left and one on the right of the
entrance. Deliveries Delivery Number, Employee ID, Sales Receipt
Number, Time the Employee Left and Returned Relates to both the
employee and the sale entities. This entity will help track deliveries. An
employee can make many deliveries but a sale is delivered by one and
only one employee. Location Location ID, Aisle, Side, Shelf Relates to
product and identifies one or more areas of the store where products are
displayed. Product Product ID, Name, Package Size, Cost, Quantity on
Hand (QOH), Last Purchased Date, Reorder Minimum Identifies the
products the store sells. One or more products can be sold per sale. The
quantity on hand allows John to determine his inventory levels. The
reorder minimum can be used to determine when the inventory level has
reached a reorder point. Sale Receipt Number, Sales Amount, Sale Date-
Time A sale is identified by a single receipt. Sales are: made to one or
more Customers but only one customer at a time. made by one or more
Register Clerks but only one clerk per sale. recorded on one or more
Registers but only one register per sale. delivered by one or more
delivery persons but no one sale can be delivered by more than one
delivery person. Sold Items Receipt Number, Product ID, Item Price,
Quantity Sold Sale Item is part of sale and records product sold per sale.
Sale item must be able to associate multiple products sold on a single
sales receipt. Customer Customer Number, First Name, Last Name,
Address, Phone Number A customer can be associated with multiple
sales, but any one sale is to one and only one customer. A sale can occur
without a customer registering in the system. Using MS Visio, develop
an ERD that meets the following guidelines: Draw the entities with their
attributes. Indicate the relationships between the entities using Crow's
Foot notation. You will need to determine the cardinality and optionality

for each direction of the relationships. Some of the Foreign Key
relationships are identified in the graph above but not all. Be sure you
identify and account for all Foreign Key relationships. Add a name (in
both directions) to the relationships. Remember, if you can verbalize the
relationship in both directions then you probably have a valid
relationship. Deliverables The deliverable for this lab will be your
completed ERD as a single MS Word document using copy/paste from
the MS Visio application and named "lab2_solutions_yourname". L A B
S T E P S STEP 1: Drawing entities and attributes Be sure to include all
of the entities that have been defined. You need to include at least the
primary and foreign key attributes where applicable in your diagram.
STEP 2: Indication of all relationships Be sure that you link all entities
based on PK to FK relationships. There may be a case where you need to
identify a combination PK and if so make sure that all of the
relationships involved are defined. Be sure that you have set your Visio
editor to show Crow's Foot notation. Also, be sure that you are defining
the correct cardinality for the relationships. STEP 3: Naming of
relationships Do not accept the default naming convention for your
relationships in all cases. There may be some relationships where this is
applicable, but in most cases you will want to explicitly name the
relationship. Be sure that you have provided a verb phrase for both
directions in the relationship. This is the end of lab #2
---------------------------------------------------------------
CIS 336 Week 3 Group Project Task 1 Data Model

Present a detailed data model for the project scenario. You can create
your data model using Microsoft Visio, which you will have access to
through iLab and Microsoft Excel, which comes with Microsoft Office.
Other tools may be used as long as the output is legible and conforms to
standard format. (i.e. I will not be able to grade the data model if I
cannot tell what it is supposed to be!). Your data model should include a
minimum of an ERD and metadata chart (data dictionary).
A key component to every task submission is the team responsibilities
document. This document should outline the contributions that each
member of the team made to completing the task deliverable. There is a
sample document in the Doc Sharing tab that can be used, or each team
can come up with their own design. As stated in the syllabus, although
this is a team project, each member will also be graded on their
involvement in the project. This assessment needs to be honest and
accurate in describing the individual members’ activities for the task.
Deliverables for this task:
A completed Data Model to include: An ERD, showing all tables,
related attributes, and the primary and foreign keys. This diagram must
show both the relationship and cardinality of the relationship using
accepted notation. A Data Dictionary (or meta data chart) showing a
minimum of the table name, columns, data types, length, and constraints.
Team member responsibilities document outlining contributions by team
members to this deliverable.
---------------------------------------------------------------

Beginning with this lab, and continuing through the remaining weeks
you will be doing all of your work in Oracle itself. The editor interface
to the Oracle server is SQL*Plus, and by now you have received your
logon ID and password and should have at least made sure you can
connect. If for any reason you have not done so, please do so now before
continuing any further. If for any reason you cannot connect then you
need to let the instructor know ASAP so that any problems can be
resolved. Before attempting Lab #3, you need to be sure you have read
through the SQL*Plus tutorial which can be found in Doc Sharing as
well as under the SQL*Plus Tutorial tab in Week 3. This tutorial
describes the functionality of the editor and will take you through the
process of setting up and using the SQL*Plus in the iLab environment so
that it will best serve your needs for the remainder of the labs required
for this course. The lab for this week addresses taking a logical database
design (data model) and now transforming that into a physical model
(tables, constraints, and relationships). As part of the lab, you will need
to download the Zip file titled "Lab 3 Support Documents" from Doc
Sharing. This Zip file contains three documents: Lab 3 Relationship
Diagram.docx, Lab 3 Meta Data Diagram.xlsx, and Lab 3 Input
Data.docx. Your job will be to take the meta data defined in the data
dictionary spreadsheet document, and using the relationship diagram as
a guide define the table structures and constraints using both CREATE
TABLE and ALTER TABLE statements. Once this has been done, you
will need to write the INSERT INTO TABLE statements to insert the

data provided into the table. The data should verify that the constraints
you have created are valid and define the correct referential and data
integrity constraints asked for. Lastly, you will write SELECT
statements to query the tables and verify the data was populated.
Narrative/Case Study For this lab, you be working with command-line
SQL to build a series of relational tables, using SQL CREATE
statements in a script file format for the Student Database and then
populate those tables through the use of INSERT statements with sample
data. You will need to create a script file and name it
YourName_Lab3.txt containing the following code: The drop table
statements listed later in the specifications of this lab. The CREATE
TABLE statements required to build the seven (7) tables. The INSERT
statements necessary to insert all of the sample data. Seven select
statements to verify that the data is in the tables and accessible. To help
you accomplish this task successfully, you are being supplied with the
following three documents which can be found in the Doc Sharing tab
on the course website: A Relationship Diagram of the database showing
in graphical form the 1:M relationships between the tables
(336_Lab3_Relationship_Diagram.doc). A Meta Data chart providing
information about table names, column names, etc. Be sure to follow
this reference exactly when constructing your CREATE TABLE
statements (336_Lab3_Data_Dict.xls). A listing of sample data to use
when writing the INSERT statements to populate the tables
(336_lab3_input_data.doc). The following guidelines are being provided
to help assist you in creating your script file: Create the tables in the
order shown in the data dictionary. Use the names for the tables and
columns as listed in the Meta Data chart – Do not change them as it will
affect your grade. Creating CONTRAINTS - Create all constraints as
indicated in the data dictionary. Constraint suffixes must be as follows:
Primary key constraint – PK Foreign key constraint – FK Check

constraint - CC Explicitly name all constraints PRIMARY KEY,
FOREIGN KEY, and CHECK constraints to reflect:
TableName_ColumnName_ConstraintSuffix (For example, to name a
PRIMARY KEY constraint on the SID column in the student table you
would use STUDENT_SID_PK.) For this lab you do not have to
explicitly name NOT NULL constraints Create all PRIMARY KEY and
NOT NULL constraints within the CREATE TABLE statements at the
column level (line level), unless the Primary Key is a composite Primary
Key (yes, there is one). Composite Primary Key constraints must be
created at the table level. Create all FOREIGN KEY and CHECK
constraints at the table level using ALTER TABLE statements. All
constraints must be added prior to populating the tables with data. Create
all of the tables and all of the constraints before populating any of the
tables with data. Insert statements must be in the same order as the tables
are created (follow the order in the sample data file). ALL character
strings must be enclosed in single quotes. This includes alpha strings and
alphanumeric (remember that any formatting within a numeric strings
makes it alphanumeric). If you are inserting a NULL, do not enclose the
word NULL in single quotes, as this will insert the word NULL into the
row. To insert a null you simply use the word NULL. Deliverables The
deliverable for this lab will include the following documents. Your script
file. Create this file in Notepad not Word. Make sure your name is in a
comment area at the top of the script file. Use a double dash to create a
one line comment: --Jacob Smith --Lab 3 Your lab output file created
using a spool session in SQL*Plus. Be sure to use the SET ECHO ON
session command when creating the output file so that both the SQL
commands and results will show in the output. Be sure your name is on
all documents and that all documents have been included in a single Zip
file for this week’s assignments. L A B S T E P S STEP 1: The DROP
statements The following DROP TABLE statements must appear at the

top of your script file. This will allow you to run and re-run your script
file as often as you need to. The first time you run your script file you
will get an ERROR on the drop statements saying the Table or View
does not exist. This is true since it has not been created yet, but the error
is more informational than anything. Once the tables are created, you
will not get this error again. DROP TABLE ENROLLMENT
CASCADE CONSTRAINTS PURGE; DROP TABLE
COURSE_SECTION CASCADE CONSTRAINTS PURGE; DROP
TABLE COURSE CASCADE CONSTRAINTS PURGE; DROP
TABLE TERM CASCADE CONSTRAINTS PURGE; DROP TABLE
STUDENT CASCADE CONSTRAINTS PURGE; DROP TABLE
FACULTY CASCADE CONSTRAINTS PURGE; DROP TABLE
LOCATION CASCADE CONSTRAINTS PURGE; STEP 2: The
CREATE TABLE statements Next, define the CREATE TABLE
statements for the seven tables that you are to create based upon the
ERD and Data Dictionary that you have been given for this lab. Be sure
to follow the guidelines given above on how and where to create the
different types of constraints for each table. STEP 3: The INSERT
statements for the data The third step is to create the insert statements to
insert the sample data into the tables created in Step 2. You might find it
helpful to take the Word document containing the sample data and save
it as a text file. After doing this, you could create the insert statements
around the actual data that is in that file. The process for doing this
should have been covered in one of the lectures for this unit. If it was
not, then ask your instructor to discuss this process with the class. STEP
4: The SELECT statements The next step of the lab will be to create the
select statements to verify the data was inserted correctly. You should
have seven select statements; one for each table. The command is
SELECT * FROM Table_Name; For example, to select all columns
from the Student table, the command would be SELECT * FROM

Student; Be sure to save all of the above statements in your script file.
STEP 5: Testing and verifying your script Now we come to the point of
verifying that your script file works by creating all of the tables and
inserting all of the data. To verify this you will need to execute your
saved script file and create an output file to capture the results being
returned to the session by using the spool COMMAND outlined in the
tutorial "Using Oracle SQL*Plus." This output file will be one of the
files you will be turning in for grading.
---------------------------------------------------------------
CIS 336 Week 4 Group Project Task 2
Task 2 - Logical Model (30 points)
Using the Oracle SQL*Plus editor, develop a database for MiniQuest
based on your data model. The database should contain all the tables and
attributes discussed in the project specifications. Be sure to use your data
dictionary when creating your tables.
A key component to every task submission is the team responsibilities
document. This document should outline the contributions that each
member of the team made to completing the task deliverable. To submit

this task, you need to create a file in notepad called
TEAM_X_TASK2.TXT, where X is your team identifier. For example,
Team A would name the file TEAM_A_TASK2.TXT. In this file, create
a heading called CREATE STATEMENTS, and then develop the
CREATE TABLE statements required to create your database tables. Be
sure to include the DROP TABLE statements at the top of your file so
that you can reuse the file. If you include the wording CASCADE
CONSTRAINTS as part of each DROP TABLE statement, then the
order of the DROP statements will not mater. For example, to drop a
table named customer, you would state:
DROP TABLE CUSTOMER CASCADE CONSTRAINTS PURGE;
After testing and verifying that all of your create statements work, create
a spooled output file with the SET ECHO ON session command set so
that your code and the results will show.
Revisions of Task 1 (if any) based on feedback from your instructor.
Task 2 comprised of the CREATE TABLE script file and the output file
showing that it works. Team member responsibilities document
outlining contributions by team members to this deliverable.

page. For instructions on how to use the Dropbox, please click here. (See
Syllabus/"Due Dates for Assignments & Exams" for due dates.) L A B
O V E R V I E W Scenario/Summary Lab #4 will introduce the various
aspects of the SQL select statement and the methods of retrieving data
from the database tables. The lab will utilize a set of tables found in the
script file (LeeBooks.sql) found in the Doc Sharing area of the website.
You will need to download the file, then run the script in your SQL*Plus
session. These tables will be used for the remaining labs in this class.
The SELECT statement is the primary means of extracting data from
database tables, and allows you to determine exactly which data you
want to extract by means of different comparison operators used in the
WHERE clause. This includes the use of specific "wild card" characters
which allow you to search for character or number patterns within the
data. You can also perform mathematical expressions within the
SELECT statement to create derived output. The ORDER BY clause
allows you to sort the output data in either ascending (the default) or
descending order. Lab #4 will explore all of these applications of the
SELECT statement. General Lab Information and Considerations Each
query in the script file you will create must be numbered (use - -1
comments for numbering) and listed in order. The SQL for the following
exercises should be written using Notepad and run in SQL*Plus. Read
each problem carefully and follow the directions as stated. A Clean
Script File: A script file is meant to be like a program. The file can be
run every time the code needs to be executed without having to retype
the code again each time. For this reason, it is important that there are no

errors in the code inside the file. You can go back and forth between
Notepad and Oracle when creating your script file to check your queries
and verify if they work or not, but you do not want to create your final
output file until after you have verified that everything in your script is
correct by running it, in its entirety at least once and viewing the output.
Once this has been done, you can create your final output file, with echo
on to create the document you can turn in with your lab. Remember in
using a spool session, you must type "SPOOL OFF" at the SQL> prompt
after your script stops spooling to capture all of your data! Lab Do's and
Don’t's Do Not include the LEEBOOKS.SQL as part of your lab script.
Do use Notepad to write your query script file. Do Not write your
queries in Word. Do test each query before moving on to the next. Do
Not include extra queries for a problem unless the problem explicitly
asks for more than one query. Do test your queries before creating your
final output file. Do Not turn in a script file that has queries with errors.
Do number each query using - -1 comment notation. Do Not start your
query on the same line as the comment. Do remember to check your
final output and script file for accuracy. Do Not turn in your lab without
first checking your output file to verify that it is correct. Things to keep
in mind: If you are not sure of the table names in your user schema, you
can use the following select statement to list them. SELECT * FROM
TAB; If you want to know the name of the columns in a particular table,
you can use the following command to list them. DESC Making a script
file containing a series of describe statements for each table and then
spooling the output will give you a listing of all the tables with column
names. Be sure to review and verify your final output when you are
finished. DO NOT assume anything. Write queries for each of the stated
problems in the steps below that will return a result set of data to satisfy
the requirements. When finished, your script file should have a total of
13 queries and your resulting output file should show both the query and

result set for each. Deliverables The deliverable for this lab will include:
Your script file with the 13 queries in it. Be sure your name, course
number, and lab number are in a comment area at the top of your file.
An output file created using SET ECHO ON showing both the SQL
code and the results. Both documents are to be zipped into a single file
before submitting to the iLabDropbox for Week 4. L A B S T E P S
STEP 1: Using the BOOKS table, write a query that will list the
categories for the books in inventory. List each category only once in
your result set. STEP 2: Using the BOOKS table, write a query that will
list the title and publisher ID for each book in the table. Use the column
heading of "Publisher ID" for the pubid field. STEP 3: Using the
BOOKS table, write a query that will list the book title, retail price, and
the amount of markup for each book. The amount of markup is the retail
price minus the cost. Use the column heading “Price Markup” for the
arithmetic expression column. STEP 4: Using the BOOK_CUSTOMER
table, write a query that will list the customer’s first name, last name,
and city for those customers living in zip code 31206. STEP 5: Using the
BOOK_ORDER table, write a query that will list everything about the
orders placed prior to April 2, 2009. STEP 6: Using the BOOK_ORDER
table, write a query that will list everything about the orders that have
not been shipped yet. STEP 7: Using the BOOK_CUSTOMER table,
write a query using the AND and OR operators that will list the
customer information for those customers living in either Florida or New
Jersey who have not been referred by another customer. STEP 8: Using
the BOOKS table, write a query that will list all information about those
books that are not computer books and do not cost more than $30.00
retail. STEP 9: Using the AUTHOR table, write a query that will list all
information about authors whose first name ends with an “A”. Put the
results in descending order of last name, and then ascending order by
first name. This should be done using a single query. STEP 10: Using

the BOOK_ORDER table, write a query using the > and < operators=""

---------------------------------------------------------------
Task 3 - Verification of Logical Model(45 points)
Develop the SQL statements to insert records into the database. You
should ensure that the data in the database is sufficient to allow for each
of the reports requested by Ms. Smith to be tested. You need to show a
minimum of three insert queries for each database table that you have
created. Some tables will obviously require more to ensure that all of the
required data is in the database (i.e., the packages table, program table,
etc). To submit this task, add a comment heading called INSERT
STATEMENTS to your corrected SQL script from Task 2. Add your
INSERT statements for each table after this heading. Keep in mind that
you will need to insert data into the tables in the same order that the
tables were created. This will minimize any integrity constraint errors
you might encounter. Keep in mind also that any values being inserted
into a field defined as a foreign key field must first exist in a previous

table’s primary key field. Save the file as TEAM_X_TASK3.TXT,
where X is your team identifier. After testing your statements to verify
that your data will insert into your tables, create a spooled output file
with the SET ECHO ON session command set for submitting.
Note – Although you are only required to have three records per table in
most of your tables for this deliverable, you will need a considerable
amount of data in your tables for the final project.
After testing and verifying that all of your create statements work, create
a spooled output file with the SET ECHO ON session command set so
that your code and the results will show.
Any revisions of task 2 based on feedback from your instructor. Task 3
comprised of the script file containing DROP TABLE, CREATE
TABLE, and INSERT statements, and the output file showing that it
works. Team member responsibilities document outlining contributions
by team members to this deliverable.

this page. For instructions on how to use the Dropbox, please click here.
(See Syllabus/"Due Dates for Assignments & Exams" for due dates.) L
A B O V E R V I E W Scenario/Summary Lab 5 deals with writing
queries using multiple tables as covered in the reading and lecture
material this week. In some cases, you will be given the option to write a
query using either the TRADITIONAL method of joining tables or using
the JOIN key word. In some cases, you will be asked to use a specific
approach. Using the incorrect process when the process is specified will
result in points being taken off for that problem. The SELECT statement
is the primary means of extracting data from database tables, and allows
you to determine exactly which data you want to extract by means of
different comparison operators used in the WHERE clause. This
includes the use of specific "wild card" characters which allow you to
search for character or number patterns within the data. You can also
perform mathematical expressions within the SELECT statement to

your output file to verify that it is correct. Things to keep in mind: If you
are not sure of the table names in your user schema, you can use the
following select statement to list them. SELECT * FROM TAB; If you
want to know the name of the columns in a particular table, you can use
the following command to list them. DESC Making a script file
containing a series of describe statements for each table and then
spooling the output will give you a listing of all the tables with column
names. Be sure to review and verify your final output when you are
finished. Do Not assume anything. Write queries for each of the stated
problems in the steps below that will return a result set of data to satisfy
the requirements. When finished, your script file should have a total of
13 queries and your resulting output file should show both the query and

result set for each. Deliverables Submit for grading: Your script file with
the 13 queries in it. Be sure your name, course number, and lab number
are in a comment area at the top of your file. Submitting ONLY your
spooled output will result in a 10-point deduction. An output file created
using SET ECHO ON showing both the SQL code and the results. Both
documents must be zipped into a single file before submitting to the
iLabDropbox for Week 5. L A B S T E P S STEP 1: Using the BOOKS
and PUBLISHER tables, create a query using the traditional join method
that will return a list containing the book title, publisher contact person,
and publisher phone number for all publishers whose publisher name
starts with an ‘R’. STEP 2: Using the DUAL table, create a query that
will return the day of the week, hour, minutes, and seconds of the
current date setting on a computer. The day should be in all upper case.
STEP 3: Using the BOOK_CUSTOMER and BOOK_ORDER tables,
create a query using the NATURAL JOIN method that will return a list
containing the customer first name and last name and the order number
for all orders that have been shipped. Give the customer name column an
alias of "Customer Name" and order the output by the customer number
in the BOOK_ORDER table in ascending order. STEP 4: Using the
BOOK_ORDER table, create a query that will return the order number,
order date, shipping address, city, state, and zip code for all orders going
to Atlanta or Austin. Format the order date to display as Month DD,
YYYY and give the column an alias of "Date Ordered". Be sure the
month begins with a capital letter. STEP 5: Using the BOOK_ORDER
table, create a query using the correct function to return the order
number, the date ordered, the date shipped, and a column representing
the number of months between the two dates for all columns where a
date shipped exists. Format the number returned from the function to
display only two decimals, and give the column an alias of "Months
Between". NOTE: Be sure that all of the numbers in the fourth column

are positive numbers. STEP 6: Using the correct tables in your schema,
create a query using either join operation that will list the title of each
book and author name(s). Give the title column an alias of "Book Title".
Sort the results by title and then by author last name. STEP 7: Using the
BOOKS table, create a query that will return the book title, cost, and
retail price for all books with a title starting with the letter ‘H’. Use the
correct conversion function to format the cost and retail columns to
show dollars and cents with a dollar sign (e.g., a price of $25 would
display $25.00 in the result set). STEP 8: Using the BOOK_ORDER,
ORDER_ITEMS, and BOOKS tables, create a query using an OUTER
JOIN operation that will list the book title, order date, and order number
for all books in the BOOKS table. Order your output in descending order
by ORDER_ITEMS.BOOKID. There are three books that have never
been ordered which should show up at the top of your listing. STEP 9:
Using the correct tables, create a query using the traditional join
operation that will list the customer first and last name, book title, and
order date (formatted as MM/DD/YYYY with an alias of “Order Date”)
for all the customers who have purchased books published by
'PRINTING IS US'. STEP 10: Using the BOOKS and ORDER_ITEMS
table, write a query using the correct Relational Set Operator that will
show all of the Book IDs in the BOOKS table that have not been
ordered. STEP 11: Using the BOOK_CUSTOMER, BOOK_ORDER,
ORDER_ITEMS, and BOOKS tables, create a query using traditional
join conditions based on comparisons between primary and foreign keys
that will list the customer number, first and last name, and book title.
Limit your listing to only those books in the ‘FITNESS’ category. STEP
12: Using the BOOKS, ORDER_ITEMS, and BOOK_ORDER tables,
create a query that will list the title, retail, quantity, and order date for all
books ordered after April 30, 2009. STEP 13: Using the correct tables,
create a query using either join operation you wish that will list the order

id, order date, quantity ordered, and retail price for every book that has
been ordered. Format the date as MM/DD/YYYY with an alias of
“Order Date” and format the retail price column using the correct
function to show dollars and cents with a dollar sign ( $ ) and a column
alias of “Retail”. This is the end of lab #5
---------------------------------------------------------------
Task 4 - Verification of Transaction Processing (30 points)
Develop a query that will identify and mark inactive those customers
that have bills overdue by more than 30 days (this can usually be done
using a sub-query). Remember, you are only marking a customer as
inactive, not actually deleting the customer record from the system.
To submit this task, create a heading called MODIFY STATEMENTS in
your group project SQL script, and name the file
TEAM_X_TASK4.TXT. This should be the same script that contains
your DROP TABLE, CREATE TABLE, and INSERT statements. Once
you have verified that your SQL statement or statements work, create a
spooled output showing the results of your statements.

Any revisions of task 3 based on feedback from your instructor. Task 4
comprised of the complete script file (DROP, CREATE, INSERT,
SELECT, and UPDATE statements) and the output file showing that it
works. Team member responsibilities document outlining contributions
by team member to this deliverable.
---------------------------------------------------------------
Week 6. L A B S T E P S STEP 1: Back to top Using the
BOOK_CUSTOMER table and the NVL function, create a query that
will return a list containing the customer number, first name, last name,
and the characters ‘NOT REFERRED’ if the customer was not referred
by another customer. Give the derived column an alias of REFERRED
BY. Do not list any customers that were referred by another customer.
STEP 2: Back to top Using the BOOKS table and the SUBSTR function,
create a query that will return a list of book ISBN codes and the book
title for all the computer books. Format the ISBN code to display as 9-
999-99999-9 (e.g., 1059831198 would display as 1-059-83119-8) STEP
3: Back to top Using the BOOKS table, create a query using the correct
functions to return the category name, the total retail of all books per
category with a column alias of "Total Retail", and the average retail of
all the books per category with an alias of "Average Retail" for all
categories with a total retail greater than $40.00. Format the total retail

and average retail columns using the correct function to show dollars
and cents with a dollar sign. STEP 4: Back to top Using the correct
tables in your schema, create a query using either join operation you
wish that will list the book title and number of authors for all books that
have been written by more than one author. Give the title column an
alias of "Book Title" and the column showing the number of authors an
alias of "Number of Authors". STEP 5: Back to top Using the
BOOK_AUTHOR and AUTHOR tables for the upper most query, create
a sub query that will return the BOOKID, and the first and last name of
the author(s) who have written the book(s) that have been purchased the
most. To successfully accomplish this, you will need to first find out the
maximum total number of copies (based on quantity) sold of a book
(based on bookid) in the ORDER_ITEMS table. This will be done in the
bottom most query. The return from this query will be used to compare
against the BOOKID in the ORDER_ITEMS table that occurs an equal
number of times in the middle query. The return of this query will then
be used to compare to a BOOKID related to an Author in the tables of
the top most query. (HINT: Be careful, you will need both GROUP BY
and HAVING clauses for your solution.) STEP 6: Back to top Using the
correct tables, create a sub query using either join operation you wish
that will list the customer number, first and last name concatenated
together, and city for all customers who have placed an order for the
most expensive book (based on retail price). Give the combined
customer names column and alias of "Customer Name". STEP 7: Back
to top Using the ORDER_ITEMS table, create a query using the correct
functions to return the item#, the total quantity of items ordered with an
alias of "Total", the average quantity per order with an alias of
"Average" (since averages are often in decimals, only show two decimal
places), the minimum quantity ordered with an alias of "Minimum", and
the maximum quantity ordered with an alias of "Maximum". Your

output results set should have five columns and four rows of data. STEP
8: Back to top Using the BOOKS table, create a query using the
DECODE function that will display the book title, the published date,
and the publisher name (this is where the decode function comes in).
Give the publisher name column an alias of "Publisher Name", and order
the publisher names in descending order. The publisher names used
should be the same as those in the PUBLISHER table. DO NOT join to
the Publisher table for this query. STEP 9: Back to top Using the
PUBLISHER table, create a query that will return a line of output like
the one below for each record in the table. Be sure to use the correct
functions in the SELECT statement, so that your output looks like the
example below. The contact person for Printing Is Us Publishing is
Tommie Seymour. Be sure to use the correct function to display the
publisher name and publisher contact with only the first letter of each
word capitalized. STEP 10: Back to top Using the correct tables, create a
query using the JOIN ON method to display a listing of all customers
who have purchased more than two books. List the customer’s last
name, the customer’s city and state, and the number of books they have
purchased. Give the number purchased column and alias of "Number
Purchased". STEP 11: Back to top Using only the BOOK table for the
upper most statement, create a sub query that will update the retail price
of all books published by PRINTING IS US by five percent (retail *
1.05). Remember, all you have is the publisher "name". Use the sub
query to find the publisher ID. To verify your update, provide a select
statement on the BOOKS table before your update statement, and then a
second select on the BOOKS table after the update. Once you have
verified the results, you can issue a ROLLBACK statement to return the
data to the original state. STEP 12: Back to top Using the
BOOK_CUSTOMER table, write a sub query that will return the names
of those customers who were referred by the same individual who

referred Jorge Perez. Do not display Jorge Perez’s name in the returned
results (Hint: you should only have two customers displayed and the
exclusion for Jorge Perez must be associated with the upper query).
STEP 13: Back to top Using the BOOKS table, create a query using the
correct functions to return the category name, total number books per
category with a column alias of "Category Total", and the total cost of
all the books per category with an alias of "Cost". Format the cost
column using the correct function to show dollars and cents with a dollar
sign. This is the end of Lab #6 Back to top]HTML
---------------------------------------------------------------
Develop the queries to support each of the reports that are required by
Ms. Smith. It is expected that the information returned by the queries is
adequate to be used in the reporting process. Make sure your output
contains enough information! The following is a recommendation and
the MINIMUM amount of data you should have access to:
Customer Table: A minimum of 12 customers (this will allow several
channels to have more than one customer selecting it as a favorite
channel) Billing Table: Records to support the above customers Program
Table: A minimum of 25 programs (your program guide should have

enough programs for various channels to support the program guide
report) Other tables: A sufficient amount of data to support the above
when reports are run
Create a heading of REPORTING STATEMENTS as a comment at the
bottom of your group project database script file. Add the six report
queries to this area. In instances where you are asked to allow for user
input, please specify an appropriate value based upon the data in your
script. For example, Report 1 is a DATE driven report; therefore, you
should use a single date in your WHERE clause to display the
information. Task 5 is the final task for the project and is designed to
demonstrate that you have adequately satisfied the requirements of the
project. The following is what you are to submit for Task 5:
Report 1 – A list of the programs on all channels for a specific day
showing the channel number, supplier, package, program name, rating
code, and show time. This will be similar to a program guide, only not
package specific. This is a date-driven report, therefore it should only
display programs for a single date specified. Report 2 – A sample
program guide showing the channel number, show time, program name,
and rating description. For the purposes of this project, your report
should be package ID specific (based on a given package ID) and you
only need to demonstrate a single package ID. Your report should
include all channels associated with the specified package. Report 3 – A
list of all new customers signed up on a specific day. This should show
enough details about the customer, including favorite channel, address,
and minimal billing details. This report is to be date driven, so you will
need to specify a date in your query. Report 4 – A list of all the
customers made inactive on a specific date. This should show enough
details about the customer to allow contact with the customer, the reason
he or she was made inactive, and the user who made them inactive.

Again, keep in mind that this is a date driven report. Report 5 – A list of
each channel (both channel name and channel number) and a count of
the number of customers who picked that channel as a favorite channel.
Report 6 – A summary of sales for any given day, categorized by
package type (i.e., the total sales written on the specified day for each
package subscribed to by customers, not bills paid). This report should
give details about each package type, the package price, the number of
packages sold, and then the total sales amount for that package. Once
again, remember that this is going to be a date driven report.
---------------------------------------------------------------
L A B O V E R V I E W Scenario/Summary There is a lot more to a
database than just tables and the data in them. A very important
part of database security has to do with using and understanding
Database Views. Being able to enhance the efficiency of the database
tables by using additional indexes is also a very important aspect of
database development. Finally, being able to create and use
Database Sequences to automate some of the sequential processes in
the database can not only save time but improve efficiency. In Lab
7, you will have a chance to work with all three of these areas.
General Lab Information and Considerations This lab will utilize

the same set of tables found in the script file (LeeBooks.SQL) that
were used for Labs 4 through 6. Each query in the script file you
will create, must be numbered (use either –1 or REM 1 comments
for numbering) and in order. The SQL for the following exercises
should be written using notepad and run in SQL*Plus. Read each
problem carefully and follow the directions as stated. A Clean Script
File: A script file is meant to be like a program. The file can be run
every time the code needs to be executed without having to retype
the code again each time. For this reason, it is important that there
are no errors in the code inside the file. You can go back and forth
between notepad and Oracle when creating your script file to check
your queries and verify if they work or not. However, you do not
want to create your final output file until after you have verified
that everything in your script is correct by running it in its entirety
at least once and viewing the output. Once this has been done, you
can create your final output file, with echo on to create the
document, you can turn in with your lab. Remember in using a
Spool Session, you must type "SPOOL OFF" at the SQL>
PROMPT after your Script stops spooling to capture all of your
data! Lab Do's and Don't's Do Not include the LEEBOOKS.SQL as
part of your lab script. Do use Notepad to write your query script
file. Do Not write your queries in Word. Do test each query before
moving on to the next. Do Not include extra queries for a problem
unless the problem explicitly asks for more than one query. Do test
your queries before creating your final output file. Do Not turn in a
scrip file that has queries with errors. Do number each query using
either --1 or REM 1 comment notation. Do Not start your query on
the same line as the comment. Do remember to check your final
output and script file for accuracy. Do Not turn in your lab without
first checking your output file to verify that it is correct. Things to
keep in mind: If you are not sure of the table names in your user
schema, you can use the following select statement to list them.
SELECT * FROM TAB; If you want to know the name of the
columns in a particular table, you can use the following command to
list them. DESC Making a script file containing a series of describe

statements for each table and then spooling the output will give you
a listing of all the tables with column names. Be sure to review and
verify your final output when you are finished. Do Not assume
anything. Write queries for each of the stated problems in the steps
below that will return a result set of data to satisfy the requirements.
When finished, your resulting output file should show both the
query statement and result set for each query. Deliverables The
deliverable for this lab will include: Your script file with the seven
queries and oneexplanation in it. Be sure your name, course
number, and lab number are in a comment area at the top of your
file. An output file created using SET ECHO ON showing both the
SQL code and the results. Be sure that you include your answer to
question #3 as a comment in this file. Both documents are to be
zipped into a single file before submitting to the iLabDropbox for
Week 7. L A B S T E P S STEP 1: Create a simple view named
CUST_VIEW using the book_customer table that will display the
customer number, first and last name, and the state for every
customer currently in the database. Now insert the following data
into the book_customer TABLE using an INSERT statement. (Do
not use the View for this insert.) CUSTOMERID - 1021,
FIRSTNAME – EDWARD, LASTNAME – BLAKE, STATE – TX.
Now query your view and display the new record. STEP 2: Create a
complex view named CUST_ORDER that will list the customer
number, last name, and state from the BOOK_CUSTOMER table,
in addition to the order number and order date from the
BOOK_ORDER table. Insert the following data into this view (use
the view for the insert statement): CUSTOMERID - 1022,
LASTNAME – smith, STATE – KS, ORDERID - 1021, and
ORDERDATE – 10-OCT-2004. STEP 3: In your own words,
explain why the insert statement for the view you created in Step 2
did not work. STEP 4: Create a sequence that can be used to assign
a publisher ID number to a new publisher. Define the sequence to
start with seven, increment by two, and stop at 1000. Name the
sequence PUBNUM_SEQ. STEP 5: Insert two new publishers into
the PUBLISHER table, one named Double Week with a contact

name of Jennifer Close at 800-959-6321, and the second one named
Specific House with a contact name of Freddie Farmore at 866-825-
3200. Use your new sequence to create the PUBID for each record.
Now, query your PUBLISHER table to see your two new records.
STEP 6: Using a single query, query the PUBNUM_SEQ to
determine what both the current sequence number is and the next
sequence number will be. STEP 7: Create a unique index on the
combined columns ORDERID and CUSTOMERID in the
BOOK_ORDER table. Give the index a name of
BOOK_ORDER_IDX. STEP 8: Determine how many objects you
currently own in your schema by querying the USER_OBJECTS
view in the Data Dictionary. Your result set should list the different
object types that you find and include a count by object type.
