> 中文摘要: 给出了一个石油管理领域应用的面向对象公共数据模型PDMM(petroleum data model for management),论述了元模型的建立与表达、类结构组织和实体定义、属性及约束规则等模型构筑技术.强调了通过引入“活动”、“特性”等超类使模型具有强大描述能力的特色,给出了模型的EXPRESS语言描述方法.
Abstract:In this paper, an object-oriented common data model PDMM (petroleum data model for management) is presented, which is constructed for petroleum resource management domain. PDMM is characterizedly its strong capacities of describing data with its definition of superclasses “activity” and “property”. The constructing techniques in PDMM include meta-model construction and its expressions, class organization, entity definition, as well as attributes and constraints. The representation of the model in EXPRESS language is also discussed.
