摘要
在诸如企业资源计划（ERP）大型复杂管理信息软件系统的开发过程中，目前越来越多地采用面向对象的开发方法和构件化的实现技术。由于这类系统目前是基于关系型数据库来实现的，所以要求在面向对象模型（OOM）和实体关系模型（ERM）之间具有规范且稳定的映射方法，以便于构件的构造。以提高构件的适应性和重用度为目标，提出了实现OOM向ERM映射的原则、方法，并且给出了在ERP系统设计中OOM向ERM映射的技术方案。该方法和技术方案已经在一个针对不同类型企业的商品化ERP系统的开发中得以有效的应用。
In the developing process of the large complicated management information software such as Enterprise Resource Planning(ERP),more and more oriented object develop methods technology of component are adopted. As this kind of system is based on the relation model database to realize at present. It is necessary to develop canonical and steady mapping methods between the Oriented Object Model(OOM) and the Entity Relation Model(ERM) in order to construct the components. This paper takes it as a goal of improvement the adaptability and reuse degree,presents the principle and method of implementing from OOM to ERM,and presents the technical schemes of mapping OOM to ERM in ERP system designs. These methods and technical schemes have already been used in a commercial ERP system development for the different kinds of enterprises.
