Research in the Workflow Engine Based on Micro Kernel
With the analysis of existing workflow engine based on monolithic kernel, a workflow engine which is based on micro kernel is designed. Service implementation and activity scheduling are separated by the engine, and then the micro kernel layer is independent and stable. All this decreased cost of engine reconstruction and difficulty of maintenance; the engine is constructed by component-based development techniques and finite state machine, which reduce the coupling between system components and increase the flexibility of workflow engine.
