Explanation

A data dictionary (or metadata repository) is a centralized repository that stores comprehensive descriptions of data elements including names, data types, lengths, constraints, and relationships. Unlike data tables (which store actual data), data records (rows), or data fields (individual cells), the data dictionary stores metadata about the database structure itself.
