Research On Long Lived Transaction In Mobile Transactional Workflow

Workflow technology is in a wide range of applications in today’s enterprise levelinformation system. With the popularity of the application, the long transactionproblem of workflow has become an urgent problem for the workflow systemdevelopers. At the same time, with the development of mobile internet technology,various wireless terminal equipment come into being, the mobile office has become atrend, while the workflow system in the mobile environment has also developed to bea hot spot, this article will focus on the analysis and research in the long transactionof the workflow and transaction workflow in a mobile environment.An important prerequisite for the workflow system reliably performing is a goodtransaction processing capabilities, so the research of long transaction workflow willhave a very important application value and theoretical significance. But with thedevelopment of wireless Internet technology and mobile terminal equipment, theapplication of the workflow technology in the mobile environment will be asubstantial increase, so the research of the transactional workflow in mobileenvironments will also be of great significance. The related algorithms andtechniques of current long transaction and mobile transaction workflow areintroduced, including the overview of transaction processing, workflow technology,the transactional workflow technology and mobile transaction workflow.This article describes the scholar’s research status and related technologies inaspect of long transaction and mobile transaction workflow both at home and abroad,analysis the model of this aspect, including the Sagas transaction model, Flexibletransaction model and Kangaroo transaction model. Through the analysis of thesetransaction models, the characteristics, advantages and disadvantages of these currentcommon workflow transaction models and mobile transaction models have to be clear,then in connection with the characteristics of human intervention needed in theprocessing of the workflow transaction proposes a long transaction workflow modelbased on semantic control—the LTW-SC model, and conducts valuable explorationon the problem of long transaction workflow in mobile environments, proposes aviable LTW-SC hybrid transaction model based on the Kangaroo transaction, a bettersolution to the long transaction workflow problem in the mobile transactionworkflow.In this paper, using the C++SIM simulator and the theoretical analysis model based on probabilistic to simulate and analysis the LTW-SC model and the LTW-SChybrid model based on Kangaroo transaction, and compare with the Sagas transactionmodel and Flexibility transaction model, and the analysis of the results show that theLTW-SC model has a more ideal withdrawal rate and execution time in the longtransaction workflow. Then the LTW-SC model is also applied to a practicalcountersigned workflow system, and successfully verified the feasibility of the modelin the practical application.
