Design And Implementation Of Automatically Generated Data Manipulation Methods In Business Process Generation Tool

With the widely use of workflow system in office automation field in recent years, how to easily operate business date during the execution of workflow nodes has become a hotspot in this field. As the lack of connection mechanism between workflow nodes and database in traditional solutions, the research status is not ideal either in flexibility or scalability. On the other hand, driven by business data model, some studies use the Artifact model describing business data, but there are still problems where the workflow nodes can not correlate with the database data on demand and thus can not manipulate data flexibly.The data manipulation method is an important part for workflow nodes to operate database. This thesis attempts to use the binding model of workflow nodes to generate data manipulation methods and data interaction pages automatically, and provide visualized editing tool for data interaction pages. The main research points are shown as follows:proposing a new method of constructing binding model between workflow nodes and database data based on Artifact model; proposing an automatic code generation technology based on Artifact model, mapping model and binding model, so as to automatically generate the data operation method and data interaction page which satisfy the business logic. Among them, design module of the operating conditions join the binding model, compared to traditional binding relationship, the accuracy of the data set has been significantly improved. At the same time, the automatic generation program handles different binding model structures separately, and obtains the data operation method which matches the business logic. The difference between the binding model is masked to the upper caller, so that the automatic generation system has good robustness.Finally, this thesis takes the object management system of the Internet of Things as an example to verify the research results. The experimental results show that the binding model construction scheme proposed in this thesis can generate the conditional data operation method and data interactive pages automatically, and the automatic generation system has good universality.
