Data validation is intended to provide certain well-defined guarantees for fitness, accuracy, and consistency for any of various kinds of user input into an application or automated system.

Data validation rules can be defined and designed using any of various methodologies, and be deployed in any of various contexts.

The time field will allow input starting with 'hh:mm' following by an optional 'am' or 'pm'. The code behind the form is as follows: For each field in the form (first the dates, then the time field), a check is made as to whether the input is blank.

When data is entered, Access checks to see whether the input breaks a validation rule – if so, the input is not accepted, and Access displays a message.

Access provides a number of ways to restrict input: You can use these methods of validating data alone or in combination with each other.

To add validation rules to a table, you open the table and use commands on the Fields tab of the ribbon.

In computer science, data validation is the process of ensuring that a program operates on clean, correct and useful data.
