Application Research Of Rule Engine In The New Rural Areas Cooperative Medical System

With the development of the computer technology and stricter requirement of software, the scale of software is becoming larger and larger, it is urgent to separate the business rule from business logic layer in order to improve flexibility and convenience for maintaining of software. It's of high significance to study software application based on Rule Engine.Firstly, this thesis introduces technology and popular products of Rule Engine, and then focuses on JBoss Rules, pointing out advantages and characteristics of Rule Engine, as well as some shortcomings on making, maintaining and user-friendly operating of business rule.After that a model of business rule parser based on JBoss Rules is proposed to solve the existing problems in practical application of Rule Engine products. This parser model utilizes Object Oriented characteristic of JBoss Rules, which treats rule file of JBoss Rules as interdependent set of relations among objects, and bridges the gap between the parser model and rule file with relational database.At last, we design and realize the Application in the New Rural Areas Cooperative Medical System, introduce the architecture of the system and application of rule Engine in the system and particularly analyze the design and realization of applying for reimbursement of medical invoices, parser model and fact model.
