Question

Write any two data validation conditions ?

Answer 1

In computer science, data validation is the process of ensuring that the data has undergone data cleansing to ensure they have data quality so that they are both correct and useful. Validation is an automatic computer check to ensure that the data entered is sensible and reasonable.

 

There are many types of Data validation operations: Data type validation; Range and constraint validation; Code and Cross-reference validation; and structured validation.

 

Simple range and constraint validation may examine user input for consistency with a minimum/ maximum range, or consistency with a test for evaluating a sequence of characters, such as one or more tests against regular expressions.
