Data Stewardship is the process of monitoring, maintaining, and enriching the value of the organization's data assets.  A data steward is a person empowered to implement the data stewardship process.  One or more data stewards are selected to determine the quality of selected data sets.  Data sets determined to be deficient in data quality are data cleansed to improve their quality.  When data sets are deficient in information content, they may be data enriched or integrated with other data sets to improve their informational value.

Many organizations are finding that poor data quality is costing them money in the form of lost business opportunity, poor customer service, as well as for many other reasons.  In some case, a data stewardship business function is implemented.  The data stewardship business function is now gaining popularity among large organizations that have a lot of data sets spread across many databases.   Tandem Primary Keys  ^tm are there to support the data steward in most every aspect of their job function.
