Research And Implementation Of Data Entity Modeling In Business Process Generation Tool

With the development of computer technology and programming methods, business process management system came into being. As a scientific and standardized procedure management method, business process management system is widely and deeply used in industry. A few procedures, which perform particular tasks individually, form a complete system in a certain logical order. However, traditional business process management system ignores the association of different tasks at data level,when only emphasizing the independence of tasks. When business needs change frequently, traditional development approach of business process management system requires programmer to modify the code in detail,the work is very hard.This paper aims to propose a method based on data entity modeling for business process management system development, which focuses on business data so that it can adapt well to the changes of business demands caused by data changes. It includes designing the entity modeling method based on the relationship between businesses, and analyzing it to generate POJO class; designing corresponding mapping rules for different kinds of nodes in the model to link fields in database; mapping model with database based on mapping rules and parsing it to generate configuration file; atomically generating methods operating data based on the data entity model and the mapping rules. Moreover, method proposed in this paper can make the modification and reuse of model more flexible, and can fully meet the complex and volatile business demands.In the end, this paper designs and implements a tool for generating business data operations based on data entity modeling, and verifies the feasibility of the tool based on product produce and sale process.Compared with traditional development method of business process management system development method, the tool is validated to significantly improve development efficiency.
