Research On Enterprise Application Integration Constructure And Engine Based On Web Service

With the increase of IT Systems and the extension of application fields,enterprise application integration has become the complicated question which enterprise must deal with while the enterprises focus on resolving the problem of oriented-operation process.Usually some solutions that are based on middleware ,API or customized codes can resolve the information isolated islands in the enterprise,But they also bring lots of difficulties in process of design development and use,what's more, they cann't provide a uniform platform to make all information systems integrated together without any gap.The paper aims at providing the enterprise application constructure named WG-EAI which is based on web service and support all kinds of integration flexibly and dynamically.Then WG-EAI engine which are based on computation grid is introduced to strengthen execution efficiency and robustness.In the end,WG-EAI transaction model will be studied to deal with loose-couple and long WG-EAI transaction.Firstly the paper show the recent development of EAI,study the four kinds of popular solution constructure and analyse the advantage and disadvantage of each constructure.Then the WG-EAI constructure based on Web Service is provided to build a middle layer which has nothing with any platform and language,so it can make the enterprise applications integrated together without gap and develop ,publish,discover and bind all kinds of applications dynamically and quickly by loose-couple and low-cost way.Application integration system need to deal with lots of information,so WG-EAI engine constructure and dynamic scheduling algorithm is provided to solve the network block and keep balance.In the end ,in order to deal with WG-EAI transaction, WG-EAI transaction model is provided and tranditional tow-stage lock protocol is extended,so system consistency state can be keep by rollback operation and compensation transactin.Lastly information integration system based on WG-EAI constructure is introduced and performance of WG-EAI grid engine is tested and analysed.At last, paper gives some deep research fields on WG-EAI in the future.
