data dictionary
Database element catalog
A data dictionary is a centralized repository describing the structure, relationships, and meaning of data elements in a database or system.
It documents field names, data types, allowable values, and definitions—metadata that helps users understand and work with the data consistently: Check the data dictionary before adding new fields.
