Answer / Tara Chand Azad
Metadata is data that describes other data. It provides information about the structure, attributes, and relationships of the data in a database or data warehouse, without actually containing the data itself. The System Catalog (also known as Data Dictionary) is a database that stores metadata within the database management system (DBMS). It contains tables that describe all objects in the database schema, such as tables, columns, indices, users, and permissions.
