Consistency

Definition:

(In the context of Data Management) a measurement of compliance with required formats, values or definitions.

Commentary:

Consistency provides assurance that data values, formats and definitions in one data population agree with those in another population. Consistency is one of the seven data quality dimensions.

Examples:
– Not logical given parameters or rules (rationalization of coding schemes)
– Invalid data formats in some records in a feed
– Telephone numbers with commas vs. hyphens
– U.S. vs. European date formats
