An Oracle database is a group of data which is considered as a single unit. The function of a database is to store and recover correlated information. A database server plays an important role in solving the problems of information management. Generally, a server consistently handles a huge amount of data in a multiuser environment so that many users can parallels use the same data. A database server also avoids unofficial access and offers proficient solutions for failure recovery.
Oracle Database is the first database developed for enterprise grid computing, the most supple and cheap way to handle information and applications. Enterprise grid computing generates large pools of industry-standard, modular storage and servers. With this architecture, each fresh system can be quickly provisioned from the pool of components. There is no hanging of the system due to heavy workloads, because capacity can be easily added or reallocated from the resource pools as needed.
Database administration is the function of handling and maintaining database management systems (DBMS) software.
