Research Web Services Composition Based On Business Process Model

Web Services Composition has become one of the most important resources recently, it also makes the Service Oriented Architecture (SOA) become mainstream paradigm of the research and development program in distributed network. Facing various Web Services, how to compose them correctly and efficiently and make it run in different software and hardware platform is an important research field.Web Services Composition idea is how to coordinate and organize Sub-Web Service according to a certain procedure, in order to construct a new web service or an application system of technology For web services assemble process, some researchers describe it as a process of choosing and organizing from existing web services to meet the specific requirement; others researchers describe it from the business process, considering that the process of Web Services Composition is a process of designing business procedure according to business requirement, and selecting and constructing the procedure of information. The former pay attention to the needs of input and output whether it is satisfied while not predetermined business processes, which is to be used to resolve the problem of services composition for the data; the latter modeling business process and according to it to search Web Services, this mode is suitable for EC and applications for enterprise.Based on the detailed analysis and reference to the existing technology of Web Services Composition and the relationship between them, then researched the theory of Web Services Composition, the article propose a model of Web service technology based on the business process. Considering the current domestic software development, we can design a model of Web Services Composition based on the business process, and describe each module's function and designing; then propose a dynamic Web Service method with semantic constraints, which automatically generate Web Services Composition scheme to satisfy the needs. In the end, the article observes and analyzes an example of batch purchasing agricultural products in this system which makes it easier and improved compose efficiency.
