Understanding of permissions and roles of oracle review notes

The permission system of the oracle database includes system permission and object permission.

Database system privilege allows users to execute specific command sets. For example, the create table permission allows users to create tables, and the grant any privilege permission allows users to grant any system permissions.

Database object privilege allows you to perform certain operations on each object. For example, the delete permission allows you to delete rows in a table or view. The select permission allows you to query information from a table, view, sequence, or snapshot through the select permission.

Each oracle user has a name and password, and has tables, views, and Other Resources created by it. An oracle role is a set of permissions (privilege) (or the access type required by each user based on their status and conditions ). You can grant or assign the specified permissions to the role and then assign the role to the corresponding user. One user can also directly authorize other users.
