Abstract: |
A compensation model is generated based on compensation and confirmation,and integrated into the original process model. The resultant model could support multilayer transaction management and bear the capability of fault tolerant and flow forward By this way,the efficiency of workflow transaction can be greatly improved. |
Key words: workflow multi-layer transaction backward recovery compensation confirmation |
