Design Study Of The Distributed Framework Based On Long Transaction

The framework of the long-lived transaction process always is the topic which the software engineers research.Its concept is the computer technology which ensures the data consistency in entire application by system container.In recent years transaction process middleware has made a big progresses which is able to work nomally in complex network entironment.CICS from ibm company and Tuxedo from bea company are among them.So software engineers in mainland start to research how to add the transaction process middleware or the transaction process technology from their own to the application framework.But the things in the world change more quickly than all that they has thought.The framework embeded long-lived transaction process middleware has expose their disadvantages because of the multifomity and the complexity of the transaction process.There is two main problems:one is that it has not been good independed in platform ,other one is that it is slow in transaction process. This paper will bring forward a new framework model,which support long-lived transaction process in the model.Because there is a good independ-platform computer language,Java computer language,the system framework chooses the computer language to implements its components and containers.In order to improve the performance of system framework this paper bring forward a new model base on the mature transaction process model in passed years.The implements technology is the main develop technology base on components drived by system container. This paper discusses how to realize the pattern and the framework design of the long-lived transaction process techinc from the direction of system.The result of the discussion is the design based on distributed object system of long-lived transaction procession (including system and programme arrangement instructure) , and realization of the pattern.The paper draws into the concept of work item set to speed the current exection of the activity in transaction process.It improves the possibility to make the transaction process run successfully but not just like nomal framwork which put emphasis on on the execute order in transaction process.
