Data Dictionary

A data dictionary is a centralized repository that defines the structure, relationships, and attributes of data elements used in a system. It includes names, types, sizes, allowable values, and descriptions of each data element. Used in databases and software development, it ensures consistency, clarity, and data integrity. It serves as a reference for developers, analysts, and stakeholders, improving communication and system documentation.
