This document discusses how to design databases and tables by determining the purpose of the database, identifying the necessary tables and fields within those tables, recognizing fields that contain unique values, and establishing relationships between tables. Key aspects include collecting related information into a database, storing attributes of individual records within fields, and following steps to first define the purpose and structure before adding data.

and Tables

2. Objectives:
At the end of this lesson will be able to:

3. Database
 A database is a collection of information related to a
particular subject or purpose.

4. Record
 A record is a collection of information that refers to a
unique individual or object.

5. Field
 A field is a unit of information used to identify the attributes
of an object. It can also be define as the column headings in
a table of information
