Use the Catalog page to get information about the entities in and available to your Oracle Autonomous Database. You can see the data in an entity, the sources of that data, the objects that are derived from the entity, and the impact on derived objects from changes in the sources.

The Catalog page lists and displays details about:

• Database objects such as Analytic Views, cloud storage links, and tables that are created by Database Actions applications such as Data Analysis and Data Load.

• Database data dictionary objects such as tables, columns, database links, analytic views, packages, and procedures that have been created by the database tools or a database application such as SQL Developer.

When you first open the Browse catalog page, it contains the Search catalog field, the Show User Preferences button, a list of recently viewed objects, and several suggested searches. You can enter a search string, click on one of the recent objects to see its details, or click on Show search suggestions icon to view suggestions on the right side of the page.

As soon as you select Catalog menu from Data Studio menu bar, the page is displayed as below.

The Catalog page contains:

1. Search catalog field

   You can search for the entities in the search field. For more details see Browse and Search Catalogs.

2. Schema

   You can search for all the entities available in the other catalog schemas listed here.

3. Faceted Filters panel

   Select one or more filter values to limit the entities shown on the page. Only those entities that match the filter values are shown. That is, the items returned by a search are filtered by these filter settings. The filters also change depending on the quick filters you select. See Filter Entities.
