1. A privilege is used for imposing restrictions on operations on certain objects.
2. Every user can grant privileges to other users for objects owned by him. Privileges on view tables may only be granted to other users when the user is the owner of the tables on which the view table is based, or when the user has the right to grant the privileges for the base tables to other users. Generally, a user is the owner of an object when he has created it.
3. Users with DBA or RESOURCE status can perform all operations on database objects that they own. The set of possible operations may be restricted for view tables, because not all view tables are updatable. If the user is the owner of a view table but not of all tables on which the view table is based, the set of operations allowed on this view table depends on the set of privileges granted to the user for the tables on which the view table is based. Moreover, users with DBA or RESOURCE status can perform operations on all objects for which they have received the corresponding privileges.
4. STANDARD users can only perform operations on objects if they have received the privileges to do so.
