Research And Realization On Web Transaction Mechanism Of Supporting The Business Process

At present,the transaction processing mechanisms are usually across multiple platforms.Their architectures of loose coupling lead to various exceptions when they are executed.Such as breakpoint exceptions,resource loosed or other problems,which can affect the quality of service.So it is necessary to adopt effective compensation measures to ensure the smooth implementation of the transaction process.In recent years,there are lots of study on the mechanism about handling exceptions.Most of the traditional web services handle the exceptions through forward recovery(restart service or find alternative)and backward recovery(rollback).But this compensation style,which is after the event,will waste resources and time.In order to resolve this problem,we put forward a web transaction processing mechanism which supports the business process.Before the execution of the transaction flow,this mechanism can not only recommend a fit transaction composite to us in dynamic environment,but also can ensure the success of the entire transaction process through making predictions and thanks to that,we can avoid the waste of resources.In this paper,there are many innovations.Firstly,we propose a new transaction processing,and make the detailed description of the architecture and function.Secondly,it is considered that the non-function restriction and the user's influence will change the result.Thirdly,the algorithm of the candidate nodes' QoS is simplified through the Skyline algorithm.And for the objective of showing the feasibility of our transaction processing mechanism,we provide an experimental system based on the example booking travel tickets online,and completed the contrast test according to the different parameters,which can prove the mechanism is scientific.
