Conformed Dimension

Conformed Dimension Definition

Underlying Concepts

Non Standard Terminology for Dimension


Completeness measures the degree of population of data values in a data set.

Record Population, Attribute Population, Truncation, Existence

Fill Rate, Coverage, Usability, Scope


Accuracy measures the degree to which data factually represents its associated real-world object, event, concept or alternatively matches the agreed upon source(s).

Agree with Real-world, Match to Agreed Source



Consistency measures whether or not data is equivalent across systems or location of storage.

Equivalence of Redundant or Distributed Data, Format Consistency, Logical Consistency, Temporal Consistency

Integrity, Concurrence, Coherence


Validity measures whether a value conforms to a preset standard.

Values in Specified Range, Values Conform to Business Rule, Domain of Predefined Values, Values Conform to Data Type, Values Conform to Format

Accuracy, Integrity, Reasonableness, Compliance


Timeliness is a measure of time between when data is expected versus made available.

Time Expectation for Availability, Manual Float

Currency, Lag Time, Latency, Information Float


Currency measures how quickly data reflects the real-world concept that it represents.

Current with World it Models



Integrity measures the structural or relational quality of data sets.

Referential Integrity, Uniqueness, Cardinality

Validity, Duplication


Accessibility measures how easy it is to acquire data when needed, how long it is retained, how access is controlled, and whether facts exist as data.

Ease of Obtaining Data, Access Control, Retention

Availability, Security


Precision measures the number of decimal places and rounding of a data value or level of aggregation.

Precision of Data Value, Granularity

Coverage, Detail


Lineage measures whether factual documentation exists about where data came from, how it was transformed, where it went and end-to-end graphical illustration.

Source Documentation, Segment Documentation, Target Documentation, End-to-End Graphical Documentation



Representation measures ease of understanding data, consistency of presentation, appropriate media choice, and availability of documentation (metadata).

Easy to Read & Interpret, Presentation Language, Media Appropriate, Metadata Availability
