Validation controls are used to validate the user's input. The validation controls can be attached to input controls to check the values that are entered by the user. You can use a validation control to perform tasks, such as checking whether a user has entered any value for the required filed, testing the entered value against a specific value or pattern of characters, and verifying that the entered value lies within a range. For example, you can use validation controls to check whether a user has entered a password, whether the enterer password contains a minimum of four characters and a maximum of twenty characters, and whether the entered password is a combination of letters and numbers.

How to connect to a database and access records is a piece of functionality that most web developers (be it Classic ASP, PHP, PERL, ASP.NET) have to contend with a on a regular basis.
