Research, Information Flow Based Messaging Middleware

With the development of information technology, the function of information ismore and more importance. "Information Flow" is that information flows between thesystems. It has much to do with every node. So information flow is the nerve center ofthe information system.Supply Chain makes up of different enterprises. Information must flows betweendifferent enterprises or departments. Because every enterprise has its own informationsystem structure, so these different structures may bring obstacle for information flow.Therefore, how to improve the efficiency of information flow is the pivotal question.Middleware is a kind of basic software. It locates between operation System andapplication software. Middleware can screen the difference of operation and networkagreement. So it can resolve the question which about information flows betweendifferent structures systems.This paper analyzed the models of information flow, combine with the idea ofmiddleware, brought forward a new information flow model which base onMessage-oriented Middleware. The new model used WebSphere MQ as its basicsoftware. Therefore, information flows more effective. Different enterprises anddepartments can share information. In this paper, the new model was used in amedicine information management system. At the end of this paper, the authorintroduced the method which about how to carry out the MQI.
