Oracle tables and views focus on the foundational concepts of storing and presenting data in Oracle databases.

This includes creating, managing, and modifying tables (the primary data storage structures) and views (virtual tables derived from queries).

This quiz is designed for those wanting to learn how to structure and retrieve data effectively and use views for improved query performance and security.

Good luck!
