Frequent Questions

How does Data Element Registry Services support Data Quality?

The DERS supports data quality by documenting, in a standard form, data about the data.  Metadata is important because if data cannot be discovered or understood, it may not be used.  If data is not understandable, the meaning is not conveyed, the data may be improperly used.  If the usage constraints are not followed, it may be improperly used by the wrong persons.
