摘　　要：探索实用的大、中型分布式数据库应用系统的开发技术。提出了面向对象的分析和设计方法、面向对象数据模型的建模机制以及面向对象模型图的描述，同时对面向对象数据模型到关系数据模型的映射规则进行了研究，提出了多种映射方案。该方法有助于设计安全稳定、可扩充和可维护的系统结构。This paper explores a practical technique for developing large and mediumsized distributed database application systems,proposes a method of analyzing and designing objectoriented MIS,and describes the mechanism of building objectoriented data models and the diagram of objectoriented models.A study has also been made of the objectoriented data models and the mapping rules of RDMs(Relation Data Model),and several mapping designs have been proposed.This method helps design safe,stable,expandable and maintainable system structures.
