基于迁移策略的动态工作流的研究与设计
Research and design of dynamic workflow engine based on migration strategy
摘要
Abstract
In order to make the workflow system to support the dynamic variable of procedure definition in operation pro-cess,the classification of workflow which may occur the dynamic modification in the process is discussed. The advantages and disadvantages of dynamic modification strategies,including restart,continuous execution and migration are analyzed. The imple-mentation of migration strategy is researched emphatically. A design method of dynamic workflow based on migration strategy is proposed. The information of process definition in the data table is loaded,and the appropriate workflow objects and their methods according to the reflection mechanism are dynamically created in this method. An executing algorithm of migration strate-gy is also designed. According to the migration rules which are written by XML,the workflow system accomplishes the conver-sion from the old workflow to the new workflow to improve the dynamic property of the workflow system.关键词
