Appendix A:

Introduction to

Microsoft Access

Part One

Database Processing:Fundamentals, Design, and Implementation


A-2

Example Database DesignThree tables: STUDENT, CLASS and GRADE


A-3

MS Access – Basic Data Types

• Text• Memo• Number

– Byte– Integer– Long Integer– Single– Double– Decimal

• Date/Time• Currency• Yes/No• AutoNumber


A-4

MS Access – Table Keys

• Each table has a key• A key is one or more columns that identify a row:

– StudentNumber in STUDENT– ClassNumber in CLASS

• Keys composed of more than one column are called composite keys:– (StudentNumber, ClassNumber) in GRADE

• See Chapter Three for a complete discussion of keys.• In this Appendix, the following keys are relevant:

– Primary key – The key used to identify rows in a table– Foreign key – The key used to link to another table– Surrogate key – A short, numeric key added to the table as an

ideal identifier when other fields don’t work as well


A-5

Example Database Design


A-6

MS Access - Relationships

• StudentNumber in GRADE creates a relationship to StudentNumber in STUDENT

• ClassNumber in GRADE creates a relationship to ClassNumber in CLASS

• StudentNumber in GRADE and ClassNumber in GRADE are examples of foreign keys


A-7

Creating a Database

UseCreate a new file…

to create a database


A-8

Creating a Table

UseCreate table in Design View

to create a table


A-9

Creating Columns (Fields)

(1) Type in FieldName

(2) SelectData Type

(3) Add a Description

(4) Modify Data Type properties on General Page


A-10

The STUDENT Table Definition


A-11

The CLASS and GRADE Tables


A-12

Adding Data to Tables

• We can add data to a table by:– Using the datasheet view, or– Using a form


A-13

Adding Data to Tables:Using the Datasheet View

Adding Data to Tables:Using a Form

UseCreate form by using wizard

to create a form


A-17


Select fields from Available Fields by using the Select

Field [>] and Select All Fields [>>] buttons


A-18


Type data into each field on the form


A-19

Creating Queries

UseCreate query in Design view

to create a query


A-20

Creating Queries

Add tables to the query

Select fields from table fields by “drag and

drop” – the * symbol means “all fields”

Add criteria to determine which rows

are selected by the query


A-21

Creating Queries

To run the query, use the menu command Query | Run or the button


A-22

Viewing MS Access SQL

To see the SQL version of the query, use the menu command View | SQL or the SQL button on the View drop-down list:

Creating Relationships

To create relationships between tables, use the menu commandTools | Relationships. When the Show Table dialog box appears, select the tables STUDENT, CLASS and GRADE. MS Access places the tables in the Relationships window.

Drag StudentNumber from STUDENT to

StudentNumber in GRADE.Check Enforce Referential

Integrity.


A-26

Creating Relationships:The Competed Relationships

The symbols“1” and “”indicate a

One-to-Many [1:N] relationship


A-27

Creating Multitable Forms

(1) As before, use Create form using wizard: Choose CLASS as the first Table/Query and add all available fields

(2) Select the GRADE Table

(3) Add only the fields StudentNumber and Grade using the [>] button


A-28

Creating Multitable Forms:The Final Form

Fields from CLASS

Fields from GRADE


A-29

Creating a Report

(1) Click Reports in the Objects list.

(2) Use Create report by using wizard.

(3) Select:

CLASS: All fields

GRADE: StudentNumber, Grade

STUDENT: StudentName
