Data Catalog: A Data Catalog is an integrated platform for data curation, matching data supply and demand. It offers users functions to register data; to retrieve and use data; and to assess and analyze data. A Data Catalog therefore should provide a data inventory (for data supply) and features for data discovery (for data demand) as key components. Additional features should support data governance, data assessment, and data analytics, alongside with appropriate features for catalog administration and data collaboration.
