WHAT IS ORACLE DBA?
An Oracle database is a collection of data dealt with as a unit. The motive of a database is to store and retrieve related information. A database server is key to fixing the issues of data management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can simultaneously access the same data. All this is done while delivering high performance. A database server also prevents unauthorized access and presents efficient solutions for failure recovery.
Oracle Database is the first database designed for organization grid computing, the most flexible and cost-effective way to control data and applications. Enterprise grid computing creates large pools of industry-standard, modular storage, and servers. With this architecture, each new device can be rapidly provisioned from the pool of components. There is no need for top workloads because capacity can be easily added or reallocated from the resource pools as needed. The database has logical structures and physical structures. Because the physical and logical structures are separate, the physical storage of data can be managed besides affecting the access to logical storage structures.
Each database requires at least one database administrator (DBA). An Oracle Database device can be large and can have many users. Therefore, database administration is sometimes not a one-person job, however a job for a group of DBAs who share responsibility. A database administrator’s responsibilities can consist of the following tasks:
- Installing and upgrading the Oracle Database server and application tools
- Allocating device storage and planning future storage requirements for the database system
- Creating main database storage structures (tablespaces) after application developers have designed an application
- Creating essential objects (tables, views, indexes) once application developers have designed an application
- Modifying the database structure, as necessary, from data given by application developers
- Enrolling users and maintaining device security
- Ensuring compliance with Oracle license agreements
- Controlling and monitoring user access to the database
- Monitoring and optimizing the overall performance of the database
