In Oracle World User is authentication, Schema is authorization

In Oracle security model, the statement is false. User authentication is WHO you are (verifying identity via passwords, certificates, OS auth), while Schema authorization is WHAT you can do (privileges, roles, permissions to access objects). The original statement reverses these - it claims User is authentication (correct) but Schema is authorization (incorrect - schemas are containers for database objects, not authorization mechanisms). Authorization is managed through grants, roles, and privileges, not schemas themselves.
