Grid architecture is the mostly employed computing architecture in enterprises and organizations. Due to its resiliency and low cost, grid architecture is the perfect solution for database and information management systems. In this article we will look at the Oracle Gird Architecture. But before we proceed with Oracle Grid Architecture, we first should recognize what a grid architecture itself is. What is Grid Computing? In fact, computers are arranged in enterprises in the form of �models�. There are several models employed in the field any each organization uses the model which suits it fit. IT systems are designed to fit these models and each company or enterprise can have minor modifications in the computing model to make it more reliable, efficient and useful. In grid computing, all the computer resources are considered as a single pool. At the same many different type of computer systems are capable of being installed or enter into this single pool. This grid computing handles and addresses each and every fragmented computer system in the pool. The problems of each fragmented computer are addressed simultaneously without any delay of time. A grid manages all the systems of a pool very effectively and all of these systems can be classified in any one of the following three categories: 1) Infrastructure: Infrastructure refers to everything that makes up the data storage and computing system in an organization. It includes all the hardware and software stuff of the pool. 2) Application: Application means the software or logic and its flow. Application is the one which controls the data, its fields and everything related to it. Application virtually moves data from one place to other enters data into a data storage system and retrieves it when required. 3) Information: Information is the thing for which the infrastructure and applications are developed. Information is the underlying thing which is controlled by every other thing. What are the benefits of Grid Computing? Grid computing is considered as the best and most reliable method to manage information of any scale. Large organizations as well as small enterprises employ grid computing architecture in their IT environment. The grid computing environment is also the cheapest and utilitarian. Lower cost of the grid computing system makes it very efficient and cheaper. Hence the repair and maintenance cost of a grid computing architecture IT system is much more cheaper than other architecture systems. Oracle grid computing architecture works best for all sorts of enterprises. An enterprise can save a lot on dedicated pieces of hardware and software which are otherwise needed to be employed in the system. Oracle gird computing databases provide more flexibility, greater access, individual access to each system in a pool, reduced costs, and all the other resources which are necessary for varying needs and demands of enterprises and individuals. The systems available by Oracle databases for grid computing architecture include: 1) Oracle Database 10g 2) Oracle Application Server 10g 3) Oracle Enterprise Manager 10g 4) Oracle Collaboration Suite 10g.
