工作流管理系统目前被用于实现先进的分布式应用系统，例如支持和控制现实世界的业务流程，如办公室程序。随着这些应用系统的日益复杂，需要在工作流管理系统中加入灵活的事务概念。利用这种高级事务特性的业务流程通常被称为“业务事务”。我们建议通过基于补偿的业务流程实例内控制流的部分向后恢复来支持业务事务。对于工作流管理系统IBM FlowMark，我们详细展示了如何扩展其元模型以支持联合补偿的范围。
Workflow management systems are used today to realize advanced, distributed application systems, e.g. to support and control real world business processes like office procedures. With the increase of sophistication of these application systems a flexible transaction concept is required to be added to the workflow management system. Business processes exploiting such advanced transaction features are often referred to as “business transactions„. We propose to support business transactions by compensation based partial backward recovery of the control flow within an instance of a business process. Work units of a business process which are defined to be potentially subject to such kind of recovery are introduced as “spheres of joint compensation„ For the workflow management system IBM FlowMark we show in detail how its metcunodel can be extended to support spheres of joint compensation.
