A checklist is useful for maintaining a list of items against which information may be stored. It is another way of displaying related data. To illustrate, lets use the following example:
We need to collect a person’s information, including all the credit cards that they have. We already have a list of credit card companies (which we can add to later). So there are three concepts here:
1. A ‘Person’ form
2. Credit Cards from well-known companies.
3. The credit card details (number and expiry date) for each person that is linked to each credit card.
