Equivalence - A characteristic of information quality that measures the degree to which data stored in multiple places is conceptually equal. Equivalence indicates the data has equal values or is in essence the same. For example, a value of "F" for Gender Code for J. J. Jones in database A and a value of "1" for Sex Code for J. J. Jones in database B mean the same thing : J. J. Jones is female. The measure equivalence is the percent of fields in records within one data collection that are semantically equivalent to their corresponding fields within another data collection or database. Also called semantic equivalence.
