Data Quality Assurance

Data Quality Assurance

Data Quality Assurance is a planned and systematic set of processes aiming to provide the desired confidence that the information embodied in a given data set conforms to established requirements. Data quality considerations are typically grouped as follows:

• Data Quality Assessment. Data quality assessment is a highly contextual process (dependent on the intended uses of the data) that establishes metrics of data quality along a number of different dimensions (Data Quality Standards)
• Data Validation that is primarily focused on validating the integrity of data
• Data Cleansing, the process of correcting and possibly transforming data in order to produce a set that is suitable for use
