To address simultaneously the problems of monolithic systems and fragmented resources, grid computing achieves a balance between the benefits of holistic resource management and flexible independent resource control. The grid style of computing treats collections of similar IT resources holistically as a single pool, while exploiting the distinct nature of individual resources within the pool. Grid computing also enables the use of smaller individual hardware components, thus reducing the cost of each individual component and providing more flexibility to devote resources in accordance with changing needs. Rather than dedicating a stack of software and hardware to a specific task, all resources are pooled and allocated on demand, thus eliminating under utilized capacity and redundant capabilities. Lower costs derive from increasing the utilization of resources and dramatically reducing management and maintenance costs. Higher quality of service results from having no single point of failure, a robust security infrastructure, and centralized, policy-driven management. The grid style of computing aims to solve some common problems with enterprise IT: the problem of application silos that lead to under utilized, dedicated hardware resources, the problem of monolithic, unwieldy systems that are expensive to maintain and difficult to change, and the problem of fragmented and disintegrated information that cannot be fully exploited by the enterprise as a whole.īenefits of Grid Computing Compared to other models of computing, IT systems designed and implemented in the grid style deliver higher quality of service, lower cost, and greater flexibility. With grid computing, groups of independent, modular hardware and software components can be connected and rejoined on demand to meet the changing needs of businesses. Grid computing is a new IT architecture that produces more resilient and lower cost enterprise information systems. Overview of Schemas and Common Schema Objects

The section contains the following topics: Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures. The database has logical structures and physical structures. There is no need for peak workloads, because capacity can be easily added or reallocated from the resource pools as needed. With this architecture, each new system can be rapidly provisioned from the pool of components. Enterprise grid computing creates large pools of industry-standard, modular storage and servers. Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications.

A database server also prevents unauthorized access and provides efficient solutions for failure recovery. All this is accomplished while delivering high performance. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data.

A database server is the key to solving the problems of information management. The purpose of a database is to store and retrieve related information. An Oracle database is a collection of data treated as a unit.
