Database Analyst Interview Question:

Tell us what are the important steps in data validation process?

Submitted by: Muhammad

Data Validation is performed in 2 different steps-

☛ Data Screening – In this step various algorithms are used to screen the entire data to find any erroneous or questionable values. Such values need to be examined and should be handled.

☛ Data Verification- In this step each suspect value is evaluated on case by case basis and a decision is to be made if the values have to be accepted as valid or if the values have to be rejected as invalid or if they have to be replaced with some redundant values.
