The Design And Implementation Of The Data Exchange System

Enterprise application integration (EAI) is a heterogeneous systems to solve business communication and emerging problems. This paper introduces the basic concepts of EAI at first and then analysis the extraction of data exchange which is an important part of EAI.The data exchange system between heterogeneous systems in the settlement enterprise makes an important role in communication. In this paper we use XML, JAVA technology, focused on JAVA EE platform, to design the data exchange system model, and to implemente one of the underlying communication module. This paper first analyzes the entire system model, introduce a system model of design, explained mainly by the system model data format conversion module, communication module bottom two modules. Used in the design of each document to transfer as a message passing thought, and used to encapsulate a unified message format document data to be exchanged to form a unified message format, The underlying communication module is to handle a unified message format to masks the actual complexity.After analyzing the overall design of the system after the data format conversion modules, the underlying communication module separately from modules of the two modules, module design, logic implementation, key techniques described in detail. In the data format conversion module, The paper introduces the advantages of using XML format, XML format used to convert the format of the ideas for the middle of the document format conversion, so we can form a multi-path of the document format conversion, improved efficiency and help extend the system later.Finally the paper introduces the design and Implementation of the entire system with an important instance of the underlying communication module using the JAVA EE platform, The paper presents the code design and implementation of the system which show the feasibility of the whole system. They have a good reference to similar projects...
