Discuss the scenarios (or your experiences) when data is not validated.

Solution

Data validation is vital to ensure the data is clean, correct and useful. Suppose if we don\'t validate the data which is received from user or any source may it will concern for the data validation because it may crash all the system. Now every system have data validation facility because they don\'t want any failure or future failure in system. For example in any online form we have fields with FIRST NAME, LAST NAME, MIDDLE NAME. But it is mandatory to fill first name and last name but it is not necessary to fill middle name. means only first name, last name field is validating not middle name.
