Data catalog vs data dictionary
Data catalogs and data dictionaries are the tools used to manage and document data assets, but they serve different purposes.
Data catalogs provide a comprehensive overview of an organization’s data assets, including metadata such as data definitions, ownership, classification, and access controls.
Data dictionaries, on the other hand, focus on defining the structure and content of specific data elements, such as data types, formats, and constraints.
While data dictionaries are often included within data catalogs, data catalogs offer a broader scope of information about an organization’s data landscape.
