Question

Write any two data validation condition

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.
