BREAKING IT DOWN…
What information is this result made up of?
Each piece of information is a FIELD.
All information relating to one thing is called a RECORD.

DEFINE THE CONTENT OF A DATABASE
Using the Video Club Fields document There are fields which are needed to join a film
club - They are the orange boxes.
Put the fields into a logical order.
How many would be needed to make a record? Why is membership number needed? Match the data item to the fields – the purple
ones.
Extension:Write your own data items onto the green ovals.

TASK 1B
In your workbook complete the Database search task – on Page 2.
Go through results with students Searching is called querying in databases When you selected additional features – this is an
AND query – the PC has to have all the features. Insight could operate without an electronic – but
it would be very slow and rely on paper and humans.
