In computer science, data validation is the process of ensuring that data have undergone data cleansing to ensure they have data quality, that is, that they are both correct and useful.
Validation is an automatic computer check to ensure that the data entered is sensible and reasonable. It does not check the accuracy of data. For example, a secondary school student is likely to be aged between 11 and 16. The computer can be programmed only to accept numbers between 11 and 16.

Hey friend !!
Here is your answer.
The restrictions applied on the data to be entered in a field is called data validation.
It is a feature of database software that checks whether the data to be entered in a field meet certain criteria or not.
Hope it helps.
