The "Autonomous Database" offers self-service tools like "Oracle Machine Learning" (B), enabling
users to build ML models directly in the database, and "Low-Code App Dev, APEX" (C), allowing rapid
application development via Oracle APEX. "Business Objects" (A) is a third-party BI tool, not native to
ADB, and "Encryption only in Object Storage" (D) is a feature, not a tool, and inaccurate (encryption is
broader). Oracle’s documentation highlights OML and APEX as key self-service capabilities.
