Testing a database involves comparing expected results to actual results to ensure accuracy. A database is considered fit for purpose if it meets the client's requirements, while changes are needed if requirements are not met. Testing is important to validate that a database works as intended.

1. TESTING AND EVALUATING A
DATABASE

2. TESTING
• It is good practice to test your database, this is done
by comparing expected results and actual results.
• Expected results – What results you want to achieve.
• Actual results – What results the database gives you.

3. FIT FOR PURPOSE
• If the database meets the client's requirements then it
is fit for purpose.
• If the database does not meet the client’s
requirements, then changes to the database need to
be made.
