Testing a database involves comparing expected results to actual results to ensure the database is fit for purpose. Expected results are what you want to achieve, while actual results are what the database produces. If the database meets the client's requirements, then it is fit for purpose, but if not, changes need to be made to the 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.
