5.01 Student Activities Notes

• How is database information used, organized, and managed in business?

For what purposes?

Database Uses in Business
I. Database Use and Purpose – A database is a tool used to organize, store,
retrieve, and communicate groups of related information.
A. Examples of databases and database uses in business and society:
1. phone book
2. online library card catalog
3. payroll data including employee names, social security numbers,
pay rates, exemptions, etc.
4. eBay and other online businesses use databases to maintain
inventory and keep track of customers, products, vendors, pay pal
accounts
B. Tables are the building blocks of all databases. They are used to group
and organize the information within a database.
1. A table is an arrangement of columns and rows. It is the
fundamental building block of all databases.
2. An entry is a single piece of data in a database table.
3. A field is a grouping or category of similar information contained in
a table; a unique identifier for a category of information
4. A record is a complete description of all of the fields related to one
item in a table.
II. Data Types, Field Properties, Primary Keys, and Printing
A. Before a database can be built, the user must first define its purpose and
determine how the data will be organized into fields.
1. Fields should be formatted in accordance with the data they contain
so that the database can be searched, used in calculations, and
sorted as needed.
2. A field name should be short and descriptive
3. A data type defines the value of a cell and a field property defines
the format of the data within the cell
B. Data types: used to control how data in a particular field will be searched,
sorted, or used in calculations. The default format is text.


1. Text – used for data that will be sorted in alphabetical order or
listed randomly, but will not be used in mathematical calculations.
2. Memo – a data type used for lengthy entries that allows
combinations of text and numbers
3. Number – used for data that may be calculated, sorted, or filtered.
4. Date/time – data type used to arrange and sort data
chronologically, often used with the input mask field property
5. Currency – data type used to format numbers as decimal values
with a dollar sign. The default format for currency is two decimal
places.
6. Auto Number – used to automatically assign a number to each
record and to assist in preventing duplication of data.
7. Yes/No – a data type in toggle format that allows a user to select a
yes or no value in a database cell. The default setting is No.
8. Lookup Wizard – a data type used to define preset values for
database entries. This feature increases productivity and accuracy
by reducing the amount of data entry required.
C. Field properties – used to control how data is entered in a field
1. Field size – used to control the size of the field, measured in
characters
2. Format – used to control the layout of the field, such as one or two
decimal places
3. Input Mask – a template-like field property that regulates how data
is entered in a cell. For example, if the phone number input mask
is used, the user will be prompted to input data in a specific format,
such as (919) 555-5555.
4. Caption – a field property used for column naming that allows a
more user-friendly and properly formatted field name than the field
name stored in the database design
D. Editing and Printing – Procedures to add and delete records and fields,
edit field names, rearrange fields in a database and print.
III. Database Management – The effectiveness of a database can be measured
by the user’s ability to retrieve useful information.
• An effective database is one that contains timely information and thus
requires continuous maintenance.
o Consider the telephone directory and the amount of information that
must be gathered, edited, and processed to provide customers with
accurate information.


• Many tools are available to assist in the retrieval, processing, and
manipulation of database information.
A. Filters allow for the retrieval of information that meets specific criteria.
1. Filter by Selection – filters for information related to an active cell
2. Filter/Advanced Filter Sort – used to define specific search
criteria
B. Sorts allow for information to be arranged in a specific order such as
alphabetical, chronological, ascending, or descending.
C. Database Relationship – a link between two or more tables in a
database
• The relationship is developed when common fields in the tables are
linked, such as the Customer ID field in a Customer Address table and
the Customer ID field in a Purchases table.
• The relationship enhances the power of the database by allowing
retrieval of data from multiple tables and eliminating the need for data
duplication.
1. Types of Relationships
a. One-to-Many is a type of relationship that occurs when a
record in one table is linked to more than one record in
another table.
b. Many-to-Many relationships are formed by connecting two
or more tables that have a one-to-many relationship. The
connection is made by a Junction Table.
2. Relationship Components
a. Primary Key – used to format each record in a database as
a unique entity. Primary keys allow database tables to
communicate.
i. May be assigned to an existing field that contains
information unique to each record.
ii. May be assigned via an AutoNumber field that
automatically assigns a unique number to each
record.
iii. The linked fields must be of the same data type and
size
b. Foreign key – when tables are linked by the primary key,
the related field in the second table is known as the foreign
key
c. Junction table – a table used to join primary key fields from
multiple tables


d. Join line – a graphical representation of the link between
two or more tables
e. Referential integrity protects related data that is stored in
multiple tables.
Referential integrity would prevent a customer in a
customers table from being deleted if the customer’s ID also
appears in the order table
IV. Raw Data Import - A useful and practical method for obtaining information
from other sources and creating database tables. Eliminates the need for
repetitive data entry and assists in the protection of the data’s integrity.
A. Must be formatted as text
B. Must be separated at field and record breaks with a separator, such as a
comma (delimitated)

Guided Practice: Filtering and Sorting a Database Teacher Demonstration


GUIDED PRACTICE: FILTERING AND SORTING A DATABASE
You will follow along with your teacher on this activity to apply sort and filter
operations to databases you have already created. You will discuss the procedures as
you proceed through the activity in order to confirm an understanding of database logic.

Part I: Retrieve the Survey database from Independent Practice: Create a
Database: Survey and perform the following tasks:

1. Filter by selection for all males. How is this accomplished?

2. Filter/Advanced Filter Sort for all females with income over $25,000

o What fields will be used in the filter?

o What operator is used for each?

3. Filter for all participants with no children

o What filter was used?

4. Filter/Advanced Filter Sort for all males under the age of 50


5. Filter/Advanced Filter Sort for all females with income over $30,000 with children




6. In your own words, describe how filter and sort operations are used to manage
information in a database. Think about the questions below when writing your
answer using the back of this handout or on a separate sheet of paper.
o What purpose does a filter or sort operation serve
o What effect do filter and sort operations have on the user who is trying to
retrieve information?
o When might a filter or sort operation be most beneficial?
o When might a filter or sort operation be least beneficial?

Part II: Retrieve the Computers database from Guided Practice: Create a
Database: Computers. Imagine that the database contains 1,000 records
and that it is an inefficient use of time to search by simply scrolling through the
entries.
Use filter and sort to answer the following questions:

1. In which room will you find the computer with the Serial Number 87093?


2. What is the Serial Number of the computer used by Student #9?

o What two methods can be used to find this information?

3. Sort the Student # field in ascending order. List the room number, manufacturer
and serial number of the next to last entry.

4. Format the Student Number field as text and perform the sort in Number 3 again.
What happens and why?

5. Search for all computers in Rooms 109 or 111. List the serial number(s).

Independent Practice: Filtering and Sorting a Database Student Activity


INDEPENDENT PRACTICE: FILTERING AND SORTING A DATABASE

You will complete this activity independently to apply what you have learned
about sorting and filtering a database. For each item, you must
copy the results of the affected field(s) into a word document. You
should end up with 9 tables in one word document. Label each
table appropriately and provide an explanation of how the sort/filter
was performed for each.

Note: Be careful not to click a yes/no box by accident and change its value

Part I: Open the B&B database and complete the following sort tasks in the HistoricInns
table.
1. Simple sort: Sort by the B&B Name in ascending order. Copy/paste the sorted
B&B field to a word processing document.
2. Simple sort: Sort by the Number of Rooms field in descending order. Copy/paste
the Inn field and Rooms field to a word processing document.
3. Complex sort: Move two appropriate fields adjacent to each other to accomplish
the sort. Primary field: Rooms in ascending order; Secondary Field: Inn in
ascending order.
If using Access, the left-most field will be sorted first, so for this sort, you must
drag the Rooms field in front of the Inn field. Copy/paste the two fields to a word
document.

Part II: Using the same database, complete the following filter by selection tasks

4. Historic Inns which do not allow pets

5. Historic Inns which allow pets

6. Historic Inns which allow children under the age of 10



7. Historic Inns located in town

(continued on the next page)



Part III: Using the same database, complete the following advanced selections

8. Apply an advanced filter that selects records according to the following conditions:
• Historic Inns that have more than 4 rooms available
• Descending order
• Allow both children and pets.
Write a criterion statement using operators

9. Apply an advanced filter that selects records according to the following conditions:
• Historic Inns that have less than 6 rooms available
• Ascending order
• Located in a small town/country place
• Allows children.
