What is the primary purpose of the Data Dictionary?

The primary purpose of the Data Dictionary is to show the data elements that belong to entities and typelists. It serves as a central repository that defines all the data elements used within an application, detailing the attributes, types, and relationships of various data entities and typelists. This is crucial for maintaining data integrity, ensuring that developers and users have a clear and consistent understanding of how data is structured and utilized within the system.

The Data Dictionary also aids in system design and development by providing essential metadata, which governs the database schema. This allows for better data management practices and helps in resolving any ambiguities about the data being used in applications. It acts as a reference for developers, analysts, and other stakeholders to facilitate seamless communication and collaboration surrounding data-related tasks.
