What is input mask in a database?
An input mask refers to controlling the input that a user is going to provide.For example, if you were going to ask for a person's phone number, and you know the format of the phone number is going to be (xxx) xxx-xxxx, then you would set an input mask forcing the input to be in that format.A zip code, for example, is 5 or 9 characters in the U.S..... either 12345 or 12345-6789.Therefore, you would use an input mask that looked like xxxxx | xxxxx-xxxxThis controls the user's input so that less validation is required later.Input masks are mostly used to validate input that has a strict pattern that never changes. With Access validation rules you can validate more complex patterns.

How critical is validation when it comes to program performance?
Validation should always be considered in a software program. The amount of validation depends on what the program is doing, and how it is doing it. If the validation is a small percentage of the overall program then it doesn't matter much how efficient it is in terms of performance. There are good and bad ways (actually inefficient ways) to do validation. If you instrument a program and find that a significant portion of the time is spent in validation you may want to visit the algorithms used in the validation to see if there is a more effective way to do this. In some cases the performance of validation of data is very important; in other cases it is a side-effect.

What are the validation controls and how many validation controls are there in ASP.NET 4.0?
Validation controls allows you to validate a control against a set of rules. There are 6 different validation controls used in ASP.NET 2.0. RequiredFieldValidator - Checks if the control is not empty when the form is submitted. CompareValidator - Compares the value of one control to another using a comparison operator (equal, less than, greater than etc). RangeValidator - Checks whether a value falls within a given range of number, date or string. RegularExpressionValidator - Confirms that the value of a control matches a pattern defined by a regular expression. Eg: Email validation. CustomValidator - Calls your own custom validation logic to perform validations that cannot be handled by the built in validators. ValidationSummary - Show a summary of errors raised by each control on the page on a specific spot or in a message box.
