The Design And Implementation Of Flexible Sales System Based On BPaaS

Business Process as a Service (BPaaS) is becoming a new challenge for cloud service platform recently, which mainly studies in the encapsulation of process model, and the dynamic running of the business process. However, There is a kind of information system which needs attention to the internal changes in process nodes during running, and the sales system is one of them.There are strong relations between process nodes of a sales system, that the system needs information from the pro-nodes when most nodes are running. Due to the process configurability, the order of the process nodes is not sure, which means the relations between the tables of the database is not sure for the relations are always determined by the order of nodes. It’s vital to make sure of the order of nodes before take the information.Based on the Development and Maintenance of sales system, this thesis did the design and implementation of a process configurable sales system based on BPaaS. The research is Mainly about:(1) Analysis of the node dynamic operation and the process constraints of the configurable sales system based on the character of BPaaS and the prototype development mode.(2) Putting forward process configuration and process node sequence determination methods based on Petri net and the accessibility verification method.(3) Implementing process dynamic operation and process constraints check based on process configuration and process node sequence determination methods.(4) Encapsulating common process nodes, realizing the process configurable flexible sales system in combination of process dynamic operation and process constraints check, and verifying the correctness and the effectiveness of it.
