In order to handle the exceptions in traditional workflow system, this paper presents a new workflow exception handling model based on ECA rules, which can effectively solve the workflow execution exception problems. The concrete design is to present a new solving model for the workflow exceptions by connecting ECA rules with transaction conception in database field, which analyses and utilizes the advanced transaction characteristics of workflow and is represented by nested transactions. This workflow exception handling model strengthens the connection with ECA rules and can effectively solve the workflow execution exceptions. The nested transaction workflow exception handling strategy and method based on ECA rules, compared to the traditional workflow exception handling frame, can better improve the effect of workflow exception handling.
