Validation:

Validation is done for comparing data with certain rules to find whether the data meets some criteria.

It is a process for checking the data whether it make some meaning or not.

Many programs perform validation at the time of entering the data or on entered data.

Assume that, there is an admission of new student...

Explanation of Solution

Type of validity checks:

Alphabetic/Numeric Check:

Alphabetic check ensures the user enters only alphabetic values to the field. For example, in the field of First Name user should only enter the alphabetic character only.

Numeric checks ensure that user enters only numeric values to the field. For example, in the field of Current Enrollment, user can enter only integer values.

Range check:

Range check ensures that the user enters a value is within a specified range. For example, assume that the lowest per credit hour fee at the school is $75.00 and the highest is $370.75.

A range check ensures whether the credit hour fee field value is between $75.00 and $370.75.

Consistency check:

A consistency check will test the data in one field or two or more fields to ensure that the relationship is logically correct and their data format is correct.

In this check, it will concentrate to maintain the physical and logical consistency of database.

For example, the field date of admission of a student in particular institution cannot be earlier in time than the value in student’s date of birth field...
