Therefore, Windows controls are highly involved in expressions. The expressions we have used so far were fairly straightforward and did not need any complex algorithm to accomplish their purpose. Unfortunately, as a database developer, you will face various scenarios, some of them might range from difficult to impossible. There are two main tools you need to build these sorts of expressions.

Data entry consists of typing values in data fields or selecting values from bound controls. Some records happen to have the same value for a particular field, or most records hold a common value for a certain field.
