Application And Research Of The EAI Based Of BPR And Virtual Component Technology

Nowadays Enterprise Application Integration (EAI) is one of the most important problems in the development of enterprise informationization. Many large IT enterprises have put forward the solutions to related business enterprises, and EAI is now becoming the hot spot. This thesis treats the application of current enterprise in the condition of the electronic commerce as the research object, and firstly analyzes the necessity of the EAI and expatiates the advantage of Business Process Reengineering(BPR) and the combination of BPR and EAI. Then analyzes the structure of EAI system and virtual component. This paper also expatiates the realized module of integration in data layer, business layer and presentation layer, and probes into the questions of data exchange, component encapsulation, the integration with the old application system.The research in this thesis is leaded by BPR, and this thesis brings up the new idea about EAI, "setting up complete enterprise business flow oriented integration system with the foundation of enterprise business flow, with the core of the virtual component technique ", by means of the knowledge of management science, computer software technique and the experience of practical development. At the same time, the paper puts forwards a new strategy of manufacturing industry business enterprise informationization: pulling enterprise information flow, logistics, capital flow and value flow by business flow, realizing business oriented efficient application integration, providing the foundation of the development of electronic commerce for enterprises.This paper also analyzes and designed the system of Enterprise Information Portal (EIP), which is a typical manufacturing industry EAI platform, and meanwhile analyzes the business process and application system in detail and realizes the data layer integration and business layer integration by means of J2EE and CORBA.
