Data Quality: The Accuracy
Dimension is about assessing the quality of corporate data and improving its accuracy
using the data profiling method. Corporate data is increasingly important as companies
continue to find new ways to use it. Likewise, improving the accuracy of data in
information systems is fast becoming a major goal as companies realize how much it affects
their bottom line. Data profiling is a new technology that supports and enhances the
accuracy of databases throughout major IT shops. Jack Olson explains data profiling and
shows how it fits into the larger picture of data quality.
