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.
B.
Examples of databases and database uses in business and society:
1.
a 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
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.
a.
Example 1: a database for an airline may contain several
tables
i.
ii.
6411 – Computer Applications I
Table 1 – Airplane Inventory
(a)
Airplane identification numbers
(b)
Dates of service and repair calls
(c)
Seating capacity
Table 2 – Flight Staff
(a)
Pilot names
Summer 2008
Unit B – 5.01 – page 1
(b)
(c)
b.
Example 2: an online store’s database might contain several
tables
i.
ii.
iii.
iv.
Table 1 contains products
Table 2 contains prices
Table 3 contains manufacturer information
Table 4 contains purchase orders
2.
An entry is a single piece of data in a database table. Examples of
cell entries in a music store database may include the price of a
CD, artist’s name, or the number the category of music in which the
CD is classified.
3.
A field, is a grouping or category of similar information contained in
a table
4.
II.
Contact information
License number
a.
Fields are unique identifiers for categories of information
b.
In the Airplane inventory example, Plane ID, Service date,
and Seats Available are examples of possible field names
A record is a complete description of all of the fields related to one
item in a table.
a.
A record is another level of organization in database tables
b.
In the Airplane inventory example, one record would consist
of the Plane ID, Service date, and Seats Available for one
plane
Data Types, Field Properties, Data Entry, and Printing
A.
B.
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 for communicating.
2.
A field name should be short and descriptive
Text-based data types and field properties – used for data that will be
sorted in alphabetical order or listed randomly, but will not be used in
mathematical calculations. For example, in a music store database, the
user may wish to sort the database in alphabetical order by artist, CD title,
song title, or genre.
1.
Yes/No – a data type in toggle format that allows a user to select a
yes or no value in a database cell
6411 – Computer Applications I
Summer 2008
Unit B – 5.01 – page 2
C.
a.
For example, the music store manager may include a field in
the database that requires a yes or no response for in stock
items
b.
The default setting is No
2.
Caption – a field property used for column naming that allows a
more user-friendly and properly formatted field name than that
stored in the database design
3.
Lookup Wizard – a data type used to define preset values for
database entries.
a.
For example, the music store database might include a
lookup wizard which provides a drop down list for the genres
of music.
b.
This feature increases productivity and accuracy by reducing
the amount of data entry required.
4.
Memo – a data type used for lengthy entries that allows
combinations of text and numbers
5.
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.
Number-based data types and field properties – used for data that may
be calculated, sorted, or filtered. For example, a music store database
may be queried for any quantity on hand that is less than ten so that the
store manager can reorder the CDs that the store is running out of.
1.
2.
3.
Decimal places – field property used to format numbers for one or
more decimal points.
a.
For example, in a music store database, the store manager
may wish to filter the database for all CDs that cost 17.99.
b.
Without the decimal format, the prices of the CDs would be
rounded off.
Currency – data type used to format numbers as decimal values
with a dollar sign.
a.
For example, in a music store database, the store manager
may wish for the database to print a receipt to each
customer which includes the total price of the CD plus tax
formatted in currency
b.
The default format for currency is two decimal places
Date – data type used to arrange and sort data chronologically
a.
For example, the music store manager may wish to view the
sales for March only in the database
6411 – Computer Applications I
Summer 2008
Unit B – 5.01 – page 3
b.
4.
5.
6.
D.
III.
Often used with the input mask field property
Time – data type used to arrange and sort data chronologically
a.
For example, the music store manager may want to compare
the sales figures for after 5:00 pm against the figures before
12:00 pm.
b.
Often used with input mask field property
Auto Number – used to automatically assign a number to each
record and to assist in preventing duplication of data.
a.
For example, the music store manager used the auto
number feature when setting up the database and is notified
when a duplicate record is added
b.
Often used with/as a primary key
Primary Key – used to format each record in a database as a
unique entity
a.
For example, the music store manager formatted the auto
number field as the primary key
b.
Primary keys allow database tables to communicate
Editing and Printing – Procedures to add and delete records and fields,
edit field names, rearrange fields in a database and print.
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.

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.
B.
Sorts allow for information to be arranged in a specific order such as
alphabetical, chronological, ascending, or descending.
C.
Database Relationships – 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.
6411 – Computer Applications I
Summer 2008
Unit B – 5.01 – page 4

1.
The relationship enhances the power of the database by allowing
retrieval of data from both sources and eliminating the need for data
duplication among tables.
Three types of relationships:
a.
One-to-One – when only one record is linked to a record in
another table.
b.
One-to-Many – when a record in one table is linked to more
than one record in another table.
c.
Many-to-Many – when multiple records from both (or more)
tables are linked. A Many-to-many relationship is actually
two one-to-many tables that are connected by a junction
table.
2.
Primary key – a field in a database table that is of the same data
type and size as a related field in a linked table
3.
Foreign key – when tables are linked by the primary key, the
related field in the second table is known as the foreign key
4.
Join line – a graphical representation of the link between two or
more tables
5.
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
6.
IV.
Junction table – a table used to join primary key fields from
multiple tables
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)

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?
o What filter was used?
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
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.
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.
Note: Be careful not to click a yes/no box by accident and change its value
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

GUIDED PRACTICE: DATABASE RELATIONSHIPS
Answer the following questions:
1. Describe and provide an example of a one-to-one database relationship between
two tables.

A one-to-one relationship between two tables means that one record in a
linked table can only be connected to one record in another table. For
example, a company may assign one car to each employee and key the
information in two tables. One table is used to keep track of the name,
address, and driver’s license number of the employee. The other table is
used to keep information on the car such as the license plate number,
mileage, make, and model. When an employee is assigned to another car,
only the common field of the two tables needs to be updated.
2. Describe and provide an example of referential integrity.

Referential integrity protects records from being deleted when they have
related fields or records in a linked database. In the example above,
referential integrity would prevent two cars from being assigned to the same
driver or two cars from being assigned the same ID number. It would also
prevent a driver from being deleted from a table if the driver is assigned to a
car.

3. Once the data is entered, set a one-to-many relationship between the PetOwners
table and the PetRoster table. It is one-to-many because the pet owners may
have more than one pet and all pet adoptions are kept on file in the PetRoster
table. Follow the procedures for creating a relationship by joining the OwnerID
field in the PetOwners table with the same field of the PetRoster table.
Notes:
4. The county restricts the number of pets per household to three. Using the
PetOwners table, determine how many additional pets can be adopted by the
following pet owners by expanding the relationship column beside each owner’s
name.
a. Tony Landis, (919) 534-3421
b. Dana Lowery, (919) 857-8568
c. Ted Hinson, (919) 854-8574
d. Phyllis Hall, (919) 851-0787
5. In your own words, explain the difference between one-to-one and one-to-many.
6. How do you know which is the “one” and which is the “many” in this relationship?

a. One-to-one is an established relationship that permits only one record
matches between two tables.
b. One-to-many is an established relationship that permits one record in one
table to match many records in another table
4. In this relationship, each dog can only have one owner, but each owner can have
more than one dog.

GUIDED PRACTICE: MANY-TO-MANY RELATIONSHIPS
Directions: For this activity, you will follow along with your teacher to complete
a many-to-many relationship. In a many-to-many relationship, two tables with a oneto-many relationship are linked by a junction table. The Beach Rentals database
contains three tables. The Properties table contains the names of the properties,
property addresses, and owner information. The Customers table lists the names
and contact information of renters. The Rentals table is the junction table.
Notes:
Which are the primary keys?
Which are the foreign keys?
If referential integrity is enforced, what affect will it have on the data?

Questions for discussion:
How can this type of relational database be used in business?
Why is it important to understand database relationships?
Why is it important to enforce referential integrity in this database?

GUIDED PRACTICE: MANY-TO-MANY RELATIONSHIPS
CustomerID is the primary key in the Customers table and it corresponds with the
foreign key, CustomerName, in the Rentals table. PropertyID is the primary key in
the Properties table and it corresponds to the foreign key, PropertyName in the
Rentals table.
With referential integrity enforced, if an attempt is made to delete a customer from
the Customers table and the customer has a matching record in the Rentals table,
an error message will appear. If this were a true company that managed beach
rentals, think about how upset the customer would be if their rental name was
deleted and they were unable to enjoy their vacation.
Class discussion questions should generate dialogue about how industries and
businesses use relational databases and why knowledge of this concept is important
for understanding how powerful and vital a database can be to a business.
