【摘要】 随着计算机技术的发展和用户对软件功能要求的提高,软件规模呈现出越来越大的趋势,迫切需要把应用系统中的业务规则逻辑从应用逻辑中分离出来,以提高软件系统的灵活性和易维护性。因此对基于规则引擎的软件系统的开发进行研究具有实际的意义。本文首先对规则引擎技术和当前主流的规则引擎产品进行了简单的介绍,其中重点介绍了JBoss Rules规则引擎。并分析了规则引擎的特点和优势,特别指出了现有规则引擎在业务规则的逻辑制定、维护和用户友好等方面存在的不足。然后作者提出了一种基于JBoss Rules的业务规则逻辑解析模型,以解决现有的规则引擎产品在具体应用中的不足。该解析模型利用了JBoss Rules规则引擎技术具有面向对象这一特性,把规则文件抽象为相互依赖的对象关系集,并利用关系数据库作为解析模型和规则文件的桥梁。本文最后设计并实现了新型农村合作医疗系统,介绍了系统的体系架构,描述了规则引擎在新农合系统中的应用实现,详细介绍了系统中医疗发票报销规则、解析模型、事实模型等的设计和实现。更多还原

【Abstract】 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.更多还原
