Introduction to Database

 What is a database?

 A database is a collection of information related to a particular subject or purpose.

 Why database?

 Keep consistent information altogether  Easy to manage and find useful information  Easy to manage related information 3 June 2003 CPSC 203 by Jie Gao

 DBMS  Database Management System  Database Objects in Access  Table   Query Form  Report  Pages …… 3 June 2003 CPSC 203 by Jie Gao

Plan for the Lab

 First part  Basic operation in Access: create table, alter table, input data, append or insert data, sort records, forms, …  Second part  Advanced operation in Access: queries, reports, …  Assignment requirements 3 June 2003 CPSC 203 by Jie Gao

Creating A Table

 Design table structure  Add fields  Select data type for fields  Set input mask for fields   Set primary key Give the table a name 3 June 2003 CPSC 203 by Jie Gao

Alter A Table

 Change in design view  Everything could be changed  If delete a field, the data in that field will be deleted 3 June 2003 CPSC 203 by Jie Gao

Edit Data

   Input data in datasheet view The format should conform to the mask Move insert point among records using the navigator at the bottom of the datasheet view 3 June 2003 CPSC 203 by Jie Gao

A Little More Work

 Sort  By a field  Ascending or descending 3 June 2003 CPSC 203 by Jie Gao

Forms in Access

 A form in Access is used to provide a friendly interface to the user  The user can input data into a table through a form created on that table  The user can also navigate data by using the form 3 June 2003 CPSC 203 by Jie Gao

Create a Form

  Two methods: Wizard or Design View Form Wizard is easy to use. You can create a form for a table on the fly!

 Design View can provide you more power. You can implement advanced features!

Form Wizard

  Select  Which fields will appear in the form You can select fields from multiple tables  Form type  Background  Name You can click “Finish” when you accept the defaults for the following steps.

Form Design View

 You can  Add controls to the form  Drag fields into the form  Adjust the form layout  Add header or footer  Even do something like programming 3 June 2003 CPSC 203 by Jie Gao
