What is a data catalog?
A data catalog is a record of an organization’s existing data. It is a library where an organizations’ data is indexed, organized and stored. Most data catalogs contain data sources, data usage information, and data lineage that describes the origin of the data and how it changed to its final form. With a data catalog, organizations can centralize information so that they can identify what data they have, distinguish data based on its quality and source.
