There could be lots of problems if there were mistakes in a database that helps carry out a task:
||Data Stored in each Record
||What if there are errors?
||Name of Child
|The wrong class may win the weekly attendance award.
Children may be trapped in a fire and nobody would know if they were marked as absent.
||Name of Product
|Customers may be charged the wrong price for their shopping.
Customers may buy food that is out of date and could make them ill.
It is therefore important that you always check a database to make sure there are no mistakes in it.
