Research On Contract Management System Base On XML/SOAP

With the fast development of software technology and Internet, the traditional two-tier Client/Server structure cannot meet the requirement of distributing, expansibility and heterogeneity in enterprise computing. In three-tier or multi-tier system framework, with the business logic separated from the Client layer, the expansibility and transplantation of the system is increased. This framework is more and more popular now in enterprise systems applications.XML-based Web Services can encapsulate information, action, the representation of data and business process uniformly. With this technology, the enterprises can pack their e-business as components and then integrate these components dynamically according to the business process.Simple Object Access Protocol is the simple protocol of information exchange in dispersive or distributive circumstances, and it is XML-based protocol.According to the software engineering standard, in Contract MI system, system analysis, design and realization processing are described, and the system structure, MVC design pattern, DataBase and interface design of XML-based Contract MI system are given, the method of MI sub-system deployed on the J2EE server BEA Weblogic is given as well. XML-RPC, XML Messaging transfer model and other key technologies are discussed, and the application of SOAP technology in Contract MI sub-system is also researched.
