'''Data verification''' is a process in which different types of data are checked for accuracy and [[data consistency|inconsistencies]] after [[data migration]] is done.<ref>http://www.datacap.com/products/features/verify/</ref>
It helps to determine whether data was accurately translated when data is [[data transfer|transferred]] from one source to another, is complete, and supports processes in the new system. During verification, there may be a need for a parallel run of both systems to identify areas of disparity and forestall erroneous [[data loss]].
A type of Data Verification is [[double entry]] and [[proofreading]] data. Proofreading data involves someone checking the data entered against the original document. This is also time consuming and costly.
