Prevention of unauthorized access and efficient solutions for failure recovery are also provided by a database server.
For enterprise grid computing Oracle Database is the first database designed to manage information and applications in the most flexible and cost effective way. Huge pools of industry-standard, modular storage and servers are created by enterprise grid computing. Each and every new system can be quickly provisioned from the pool of components with the help of this architecture. When required capacity can be easily added or reallocated from the resource pools so there is no need for peak workloads.
The database consists of two structures: logical and physical. The logical structures including table spaces, segments, and extents, dictate how the physical space of a database is used. The physical structure is determined by the operating system files that constitute the database. The physical storage of data can be controlled without affecting the access to logical storage structures due to the reason that the physical and logical structures are separate (Michele, 2005).
