A task that all good programmers should always do is to verify and validate that the data inserted into a form is correct for that field. To do this it`s useful to have Data Entry Validator. It lets you validate the entry data and restrict them to a predetermined type (whether numeric, alphanumeric, date, decimal or even defined by the user themselves).
Data Entry Validator comes equipped with a series of functions that help you validate the text inserted and, this way, know if they are correct. Once correct they are then fit to be inserted into a database. You can even limit the maximum number of characters to be written, and make them all capitals or lower case.
Thus, with the Data Entry Validator restrictions, you are guaranteed to have users of your programs writing the correct data.
