Definition:

The strength of the relationship of data in one field to the data of another field. It is measured by internal consistency (numeric agreement between fields or the logical relationships between fields), temporal consistency (stability of data fields across time), and linkability (connections of one data file to another using a unique subject-specific identifier).
