Appendix-2

Chapter Objectives

• Learn how to use Microsoft Access to:– Create tables– Create relationships– Create queries using the query design tool– Create basic forms– Create forms with lookup combo boxes– Create basic reports– Create parameterized reports


Appendix-3

Creating the Database Design

• Before you begin using Microsoft Access, you must know what to create

• This entails creating a data model and the corresponding data schema

• The DBMS will not help you in this process

Appendix-5

Database Schema

• A database schema is a design of database tables, relationships, and constraints

• Schemas are developed by analyzing user requirements such as forms, queries, and reports, and then constructing a data model

Enter the DBMS

• Now that the tables and relationships have been conceptually defined, the DBMS may be used to actually create the database objects


Appendix-12

Creating a Table with Microsoft Access

Double-Click the “Create table in Design view” Option


Appendix-13

Entering Field Characteristics

• Enter the Field Name, Data Type, and Description (optional) for each field

• Click and Drag to include all Fields that are part of the Primary Key

• With all fields making up the Primary Key highlighted, click the Primary Key Button


Appendix-14

Microsoft AccessTable Define View

Primary Key Button


Appendix-15

Close the Table Design View and Save

• To save the table, simply close the design view window and type a name for the table


Appendix-16

Microsoft AccessSaving the Table


Appendix-17

Creating the Remaining Tables

• Follow the above procedure for the remaining tables


Appendix-18

Defining a Composite Primary Key

All fields defining the Primary Key are highlightedbefore clicking the Primary KeyButton


Appendix-19

Informing the DBMS of the Foreign Key Constraints

• The DBMS must be informed about what Primary Key is mapped to what Foreign Key.

• This defines the database’s Referential Integrity


Appendix-20

Microsoft Access: Relationships View

• Within Microsoft Access the referential integrity constraints are defined in the Relationship View Window by:– clicking on the Primary Key, then– dragging it to the Foreign Key, and– dropping it on the Foreign Key


Appendix-21

Relationships View

Click to enter the Relationships View


Appendix-22

Select the Tables to be Included

Add each table to the Relationships View Window by highlighting the table nameand clicking the Add button


Appendix-23

Arrange Tables in Relationships View

Click and Drag to arrange the tables

to avoid crossing relationship lines.


Appendix-24

Creating a Relationship

Field Names

Enforce ReferentialIntegrity = Checked

Define Cascading Rules


Appendix-25

The Resulting Relationship


Appendix-26

Create the Remaining Relationships

• Drag each Primary Key Field and drop on the appropriate Foreign Key field to create the remaining relationships

• Enforce referential integrity for each remaining relationship


Appendix-27

The Final Relationships View Window


Appendix-28

Creating Queries

Click the Queries Tab


Appendix-29

Creating a Query inDesign View

Appendix-34

Forms

A form a graphical display for adding, updating, viewing, and deleting data from one or more tables


Appendix-35

Creating a Form
