Which statement is FALSE about the Catalog tool?
- A. Impact shows the entities that depend on the source.
- B. You can limit the display of entities to only those with certain names, schemas, types, or applications by entering values in the Search field.
- C. You can delete an entity from the Autonomous Database via the Catalog tool.
- D. You can view the data definition of an entity.
Answer: C
Explanation:
The Catalog tool is a built-in feature of Autonomous Database that provides an easily searchable inventory of all the objects in, or accessible from, the database, such as schemas, tables, views, columns, analytic views, files on cloud object storage, and more1. However, the Catalog tool does not allow you to delete any entity from the database. You can only view the details, lineage, and impact of an entity using the Catalog tool2. To delete an entity from the database, you need to use other tools such as SQL Developer Web or APEX3. Reference:
