data validation tasks

Posted 25 May 2014 - 12:00 PM

hi,
can someone please tell me the definition of data validations tasks. I am thinking this involves checking if the data being inputted is clean (i.e no duplicates, data types are accurately identified primary & foreign keys are in place e.t.c) my thinking is that to ensure this, you would use constraints that you stated during creation of the database.
also my 2nd question..where does these data validation tasks come in when migrating to a new database or trying to move data between two different systems.

Is This A Good Question/Topic? 0

Doesn't sound right, but:

Data validation is the process of checking incoming data for clean, correct, needed data in a program.

Question 2: switching from system to system the data should not change, but you have business rules in both systems validating data regardless of where it came from.
