A database server is having a key to solve the problems of information management. In general a server manages a large amount of data in a multiuser environment so that many users can concurrently access the same data at a time or separately.

A database server also prevents unauthorized access to the database and provides efficient solutions for failure recovery so next time we can recover that problem.

Oracle Database is the first database which is designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications of oracle. Using this architecture, each new system can be rapidly provised from the pool of components.

The database has both the strucutres as logical structures and physical structures. Because the physical and logical structures are separate with each other, the physical storage of data can be manage without affecting the access to logical storage structures.
