DBMS_DCAT package provides functions and procedures to
help Autonomous Database users leverage the data
discovery and centralized metadata management system of OCI Data Catalog.
Data Catalog harvests metadata from a data lake's object storage assets. The harvesting process
creates logical entities, which can be thought of as tables with columns and associated
DBMS_DCAT procedures and functions connect Autonomous Database to Data Catalog and then synchronize the assets with the database, creating protected schemas and
external tables. You can then query object store using those external tables, easily
joining external data with data stored in Autonomous Database. This dramatically simplifies the management process;
there is a single, centrally managed metadata store that is shared across multiple OCI
services (including Autonomous Databases). There are also Autonomous Database dictionary views that
allow you to inspect the contents of Data Catalog using SQL, and show you how these Data Catalog entities map to your Autonomous Database
schemas and tables.
