Backup and Restore
Any DBA worth their knowledge should know the DBMS’ (Database Management System’s) built-in methods to back-up and restore data, such as using Oracle Restoration Administrator, but in addition to these built-in resources, it also seems sensible to comprehend Third party promotions are available. Business back-up alternatives are used in many bigger IT stores. Be acquainted with products such as NetBackup or NetApp SnapManager.

As a DBA you should help them understand when it is better to carry out handling on the DBMS rather than in rule. Taking amounts of information across your system to carry out a sum is most likely more slowly than composing a query with a total function.
Storage Systems
In most databases the main bottle neck is hard drive access. Understanding where your database is saved and how the DBMS accesses the physical information is significant. Is your database on local hard drive or a SAN (Storage Area Network)? If your company has a storage space group, get to know them, and know what resources they use to monitor.
Knowledge of SQL
