'''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> In some domains it is referred to Source Data Verification (SDV), such as in clinical trials.<ref name="pmid25327707">{{cite journal| author=Andersen JR, Byrjalsen I, Bihlet A, Kalakou F, Hoeck HC, Hansen G | display-authors=etal| title=Impact of source data verification on data quality in clinical trials: an empirical post hoc analysis of three phase 3 randomized clinical trials. | journal=Br J Clin Pharmacol | year= 2015 | volume= 79 | issue= 4 | pages= 660-8 | pmid=25327707 | doi=10.1111/bcp.12531 | pmc=4386950 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25327707 }} </ref>

ItData verification 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]].

AMethods type offor data verification isinclude [[double data entry]] and [[proofreading]] data. Proofreading data involves someone checking the data entered against the original document. This is also time consuming and costly.
