Data Dictionary


Definition: A data dictionary is a centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format.

What This Means: To the educator, the data dictionary is the authoritative course for definitions, codes, and interpretations for all data elements and derived statistics for an education agency. At this level, the term metadata dictionary is appropriate. For the IT professional, the data dictionary is more technical, describing the tables, fields, and codes around which a database is designed and constructed.
