Abstract: Due to the exceptions existing in the workflow systems,in this paper,a transaction based workflow exception handling model;the mechanisms for monitoring analyzing and handling of exceptions;and the additional methods for triggering and backward recovery;are presented.The exceptional event base according to ECA rules have been established.The monitoring,analyzing and handling of exceptions are realized,a monitoring algorithm is also given.Based on these,the methods and algorithms of static and dynamic modification for the workflow to solve the data consistency and correctness after exception handling are discussed.

Key words: workflow, exception handling, transaction, data consistency
