摘要

摘要: 以当前第三代地理数据库模型和PRB数据模型为基础, 通过PRB数据流“栈”与不同阶段数据模型的关系说明PRB数据流“栈”是不同阶段数据模型继承和传递的基础; 阐明了最终解释成果空间数据库的数据模型是在不同阶段结构化与非结构化数据模型关系上通过抽象与综合来实现“继承”的; 用对象类和要素类的互操作来实现空间与非空间的属性继承传递.同时, 基于地质图一体化的描述、组织和存储的数据建模原则, 得出了基于PRB数据模型为基础的PRB地质图空间数据库由17个基本要素类、6个对象类、8个综合要素数据集构成.并对实体名称、要素与对象编码、空间数据类型、实体间的关系、主关键字名称、子关键字名称、注释要素类编码、实体属性内容说明进行了定义和说明

Abstract: Based on the third generation geography database model and the point-routing-boundary (PRB) data model, this paper explains that the PRB data stream stack is the inherited and transferred foundation of data models in different digital mapping stages. This is done by using the relationship between the PRB data stream stack and different-stage data model. It shows that the date model of the database, which includes the final-interpretable results, can inherit from the integration of the different-stage structure and non-structure data model, and clarifies that the inherited and transferred technique of spatial and no spatial attributes have been implemented by using inter-operation between object class and feature class. At the same time, in terms of the data molding principle of the integrative describing geological map, organizing data and storing data, it is concluded that the PRB data model of the PRB geological map spatial database is composed of seventeen basic feature classes, six object classes and eight synthetic feature classes. This paper also defines and discusses some elements of the PRB data model, including entity names, feature and object class coding, spatial data types, entity relationships, primary and subordinate key names, coding of feature classes notation, and entity attributes.
