摘要: 回退是工作流管理系统的一个重要功能,传统的回退方法大多是单步的、逐级的、禁止跨and合并或跨and分支的,不能很好地满足企业业务流程的多变性及复杂性。基于此,通过改进回退规则和回退算法,运用改进后的规则和算法对shark引擎进行二次开发,实现一个支持流程多步回退的应用模型。实验证明,改进后的引擎较好地解决了工作流流程的多步回退问题,保证回退时数据的一致性和流程死锁的规避。

Abstract: Rollback is one of the important functions of the workflow management system. The traditional methods of workflow rollback are single-step, stage by stage, prohibit cross-and-join and cross-and-split, which cannot meet the requirements of the changeability and complexity of the enterprise business processes. Based on the improvement of rollback rules and rollback algorithm, an application model is realized with re-development to the shark. Experiments show that the regenerated engine solves the problems of multi-step, ensures the data consistency and avoids the deadlock during the rollback.

Key words: workflow, multi-step rollback, shark engine, data consistency, deadlock
