CIS 336 Group Project
www.cis336.com
This project is designed to touch all aspects of the fundamental
concepts of database design and logical data modeling covered during
the class. Each student will be responsible for designing, developing,
and demonstrating the functionality of a database created based on a
set of business specifications that you create. At the end of the
session, each student will submit a report that includes the logical and
physical design of the database and demonstrates the database's ability
to deliver meaningful reports. All aspects of the project will be

covered during the week or weeks prior to a deliverable, and each task
deliverable in the project will be supported through the exercises and
labs done in the course.

CIS 336 iLab 1 Normal Forms and Entity Relationship
Diagrams
www.cis336.com
CIS336 Lab 1: Normal Forms and Entity Relationship Diagrams
Introduction
In this exercise, you will analyze a de-normalized data set presented
in the form of a spreadsheet. You will next construct a series of
dependency diagrams, transforming the evolving data model from
First Normal Form (1NF), to Second Normal Form (2NF), and finally
to Third Normal Form (3NF). When the model has reached 3NF, you
will construct the Entity Relationship Diagram (ERD) depicting the
logical design of the database. Your ERD will use Crow’s Foot
notation to denote the relationships between tables.
Sample Exercise, With Solution
Before completing your lab, please review this example problem. The
diagram below is a partial depiction of a business spreadsheet for a
retail store operation. The store sells books. Books have a 13-digit
International Standard Book Number (ISBN), a title, a publisher, and
a unit price. Invoices track sales of books. An Invoice contains one or
many line items, with each line item reflecting the sale of one or more

copies of a specific book. Every publisher has a company name, and a
publisher code.

CIS 336 iLab 2 The Expanded Entity Relationship Diagram
www.cis336.com
CIS336 Lab 2: The Expanded Entity Relationship Diagram
LAB OVERVIEW
Scenario and Summary
This lab introduces the next step in creating a data model, the Entity
Relationship Diagram (ERD). You will be given a business scenario
for a University Medical Center, which is a small community
hospital. 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 that 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. Make sure to use Crow’s Feet notation in
your ERD.
Narrative/Case Study
The University Medical Center is a small, community hospital. A new
hospital administrator has recently been hired by the Board of

CIS 336 iLab 3 Building the Physical
www.cis336.com
CIS-336: Lab 3: Building the Physical
LAB OVERVIEW
The lab for this week addresses taking a logical database design (data
model) and transforming it into a
physical model (tables, constraints, and relationships). As part of the
lab, you will need to download the
zip file titled CIS336Lab3Files from Doc Sharing. This zip file
contains the ERD, Data Dictionary, and test
data for the tables you create as you complete this exercise.
Your job will be to use the ERD Diagram found below as a guide to
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. Please use exactly the data provided, without
addition, deletion, or alteration

Delete Statements (only SQL Command, No output)
www.cis336.com
CIS336: Lab 4: Introduction to Select, Insert, Update, and Delete
Statements
LAB OVERVIEW
Lab 4 will introduce the various aspects of the SQL select statement
and the methods of retrieving data from the database tables. This lab
will also introduce the fundamentals of updating and deleting records.
This lab may be completed using either DeVry’sOmnymbus EDUPE-
APP lab environment, or a local copy of the MySQL database running
on your own computer using the OM database tables. The lab will
utilize a set of tables that are represented by the ERD

(OM_ERD.docx) and are created and populated by the script file
(create_OM_db.sql). Follow the instructions in the file
CreateOMTables.docx to create your database, tables, and data.
A few IMPORTANT things to note if using EDUPE MySQL:

www.cis336.com
CIS336: Lab5: Joining Tables
LAB OVERVIEW
Lab 5 will introduce the concept of multi-table JOINS in order to
work with data in two or more related tables simultaneously. This lab
may be completed using either DeVry’sOmnymbus EDUPE-APP lab
environment, or a local copy of the MySQL database running on your
own computer using the OM database tables. The lab will utilize a set
of tables that are represented by the ERD (OM_ERD.docx) and are
created and populated by the script file (create_OM_db.sql). Follow
the instructions in the file CreateOMTables.docx to create your
database, tables, and data.
**There can be NO SPACES in alias names given to a column. For

are represented by the ERD (OM_ERD.docx) and are created and
populated by the script file (create_OM_db.sql). Follow the
instructions in the file CreateOMTables.docx to create your database,
tables, and data.

Select unit_price as Retail_Price from items;
Select unit_price as RetailPrice from items;
**Any calculated fields MUST be given an alias (and note above NO
SPACES in alias). For example:
select unit_price * 2 from items; –this does NOT work in EDUPE
MySQL
This will work:
select unit_price * 2 as NewPrice from items;
