Database
Access Permissions
Provide different access rights for different users to prevent the database from being damaged by external or inadvertent users, and set the policy to allow legitimate users to operate.
Backup/Restore
Allow users to easily "back up" or transfer data in the database, in case the system is damaged, and "restore" the data back to reduce losses.
Data Access
Includes retrieval, insertion, modification, and deletion to help users access data quickly.
