面向对象数据模型构筑
Constitution of Data Model of Oriented object
【摘要】 介绍了POSC软件集成平台中Epicentre逻辑数据模型关系实现的基本原理,Epicentre逻辑数据模型在其关系实现过程中需要考虑的主要因素,以及POSC组织制定的对Epicentre逻辑数据模型进行扩充和裁剪的规则;分析和总结了在实现应用数据模型构筑时必须考虑的一些附加性因素;综合以上规则和因素,论述了基于面向对象逻辑数据模型的应用数据模型构筑的实现过程,以及实现过程中的设计依据.
【Abstract】 The relational implementation principle of Epicentre logical data model in POSC software integrate platform is discussed in brief. Some primary factors are given, which must be considered during the relational implementation of Epicentre logical data model. In the meanwhile, some ragulations on extension and subsetting Epicentre logical data model designed by POSC are described. Some other factors that must be considered during the constitution of application data model are pointed out, analysed and summed up through experiments. All of these are the basis of the constitution tool design of data model of oriented object. According to these, the steps used to constitute application data model on the basis of Epicentre logical data model are established.
【Key words】 POSC; Epicentre model; oriented object data model; data mapping;
