Research Of A Workflow Cooperative Model Based On Grid Services

Web services is a good package, loosely coupled, highly integrated features such as capacity, to solve workflow management application modules scattered and application software integration platform being not uniform. But Web services is unable to properly resolve the service how to create, manage, and other issues. Grid services not only inherits the advantages of Web services, but also to achieve a wider sharing of resources and management, How to solve the service creation, management, and other issues. Grid services will be applied to the technical work flow collaborative work, not only to resolve work flow application modules dispersed, Application software platform is not unified, but also can make full use of grid resource sharing and grid service easy Packaging loosely coupled, increased network efficiency in the use of resources, but they can be compatible to the existing historical system, enhance the flexibility of the application and code reuse rate, to protect the investment users have.The paper systematically studies the Open Grid Architecture (OGSA). Open Grid Services Infrastructure (OGSI) and the grid service technology; Analysis of the Grid Service Construction work flow system for the coordination of the process definition, the implementation of such technologies; Analysis of the Grid services and the characteristics of grid services in the sharing of resources, shielding heterogeneous entities, and other strong points.The paper focuses on the design of Grid services based on collaborative workflow application model demonstrated that the application of business logic model, implementation services, and other services to achieve the level of technical support and analysis of the grid services in the description, registration, call key technology, and gives the workflow engine operating mechanism of the general method. The work flow application model can not only solve application modules scattered, not unified application platform and other matters, also make full use of grid resource sharing and grid service easy Packaging loosely coupled nature.A logistics management system to order goods online business needs, Based on the grid service workflow model of synergy realization. For the business grid service is the realization of a detailed design of the grid service description, registration, calling the process definition and implementation of key technologies, such as a pilot, The results showed grid service business processes work together to take full advantage when the grid sharing of resources, Applications can also solve the conflict of heterogeneous entities.
