A data dictionary in a database is a central repository of metadata about the data within the database. It stores information about tables (names, columns, data types, constraints), views, indexes, users and permissions, and constraints. Benefits include improved data quality, enhanced data understanding, simplified database development and maintenance, and improved data security. The data dictionary is a critical component of any database system, providing essential information about the structure, content, and relationships of the data within the database.
