Research And Application Of Grid Service In Distributed E-Commerce

As a new type of commercial model, e-commerce develops rapidly all over the world. However, seen from the whole e-commerce's field some small enterprises' e-commerce business remains stagnant for a long time for lack of capital;some large fully reinforced ones have negative aspects like capital redundancy, consequently, resources waste. Based on this, we assume that if we can combine all kinds of resources such as calculation, storage, telecommunications and software in the Internet, we can connect them on the united platform, provide standard procedures, a group of instant use, perfect function and secure e-commercial services, which makes full use of the resources, makes the enterprises or departments share information and business procedures with each other, and as a result, IT systems in e-commerce fields can be combined efficiently.The emergence of grid technology provides our assumption with theory and technology base. The essence of grid is an integrated calculation or resource environment. Its aim is to put all the physics and logical resources into an invented environment with super calculation ability, to share information fully and handle some problem in coordination. The exploitation OGSA is the most important organization of grid system. Based on the grid application, it defines a common, standard and open architecture. Taking services as a center, OGSA emphasizes the combination of practical position's transparency plus multicontract, and based on the web service standard, and providing the realization of grid's commercial application with convenient information, sharing procedure and operational system.Firstly, this thesis analyzes the problems in the traditional e-commerce and proposes the ideas for design e-commerce system based on the grid service. Secondly study on the grid technology and it's relative architecture and development platform. Based on the above advanced properties, this thesispresents a distributed e-commerce model that based on grid service innovatively, and then research on its technology and principle. Applying this model, this thesis defines the design aim of e-commerce on the basis of the grid service, system arrangement, system structure and concrete procedure. Finally, to testify the study's scientificalness and practicalness, the thesis exploits and realizes proto-system.The distributional electronic commerce application model based on grid service proposed by this thesis has realized dynamic effective integration to the distributed isomerism data resources, and provides a realistic reference solution for establishing a electronic commerce operation environment that has the conformity, the opening, the independent characteristic.
