Abstract: This paper describes the design of a model to provide support for distributed workflow transactions and proposes a flexible transaction model.The definition of the flexible transaction model is given. And the serializability correctness criterion that ensures the correctness of flexible transactions is specified. This model has the ability to manage the arbitrary distribution for business processes over multiple workflow management systems.
