Data Verification and Extraction

Data verification is done to ensure that there are no inconsistencies, to check quality, authenticity and that the data is accurate. When data is passed from one source to another, verification is performed to ensure that it was correctly translated. To eliminate data loss areas of variance are identified and corrected. Data verification is especially useful for the retail industry where large amount of data are collected and its authenticity and accuracy has to be ascertained to enable corporations to make informed corporate decisions.
