What is the primary use of data dictionaries in database design?

The primary use of data dictionaries in database design is to outline table structures and field properties. A data dictionary serves as a centralized repository that describes the elements within a database. It includes detailed information about table schemas, such as the names of tables, the names and data types of fields, constraints, relationships between tables, and descriptions of the data stored.

This comprehensive documentation is invaluable for developers and database administrators, as it facilitates better understanding and management of the database. By having a clear outline of table structures and field properties, teams can ensure consistency, maintain data integrity, and streamline the process of querying and reporting from the database.

Other options, while relevant to software or user interface development, do not pertain specifically to the organization and specification of data within the context of database design.
