Azure Data Catalog is a fully managed service (for enterprises) whose users can discover the data sources they need and understand the data sources they find.

With Azure Data Catalog, any user (for example, business analyst, data scientist, or developer) can discover, understand, and consume data sources.

With Azure Data Catalog, you can register all your data sources and can contribute metadata and annotations to these entries. You can also define the relationships between the different data sources and control the access via a fine-grained legal system.
