工作流数据的一致性保护框架

目前的工作流系统普遍缺乏保证工作流事务特性的措施，这是影响工作流系统进一步普及与实用化的一个重要原因。本文提出了一种以工作流数据为核心的数据一致性保护框架，包括对工作流控制数据的失败处理模式，对工作流相关数据的多版本管理机制和对工作流应用数据的加锁协议等，从而全面保证各类工作流数据的一致性，使工作流程系统具备较为实用的事务处理能力。

A Consistency Protecting Framework for Workflow Data

Currently, many Workflow Management Systems (WfMS) lack the capability of preserving the transactional characteristics of the workflow. It is an important reason for the workflow pervasion and practicability. In this paper, a comprehensive data consistency protecting framework oriented to the three kinds of workflow data is introduced. It includes the failure operation patterns for workflow control data, the multi-version management mechanism for workflow relevant data and the lock protocol for workflow application data. Under this framework, the WfMS will be provided with the powerful and available transaction capability and can keep the consistency of the workflow data.
