基于对象—关系—属性数据模型的空间半结构化数据存储管理研究

Storing and Maintaining Semi-structured Spatial Database Based on Object-Relationship-Attribute Model

对象—关系—属性数据模型相对传统的结构化数据模型,用更丰富的数据语义区别了对象类属性和关系类型属性两个概念,使其适用于半结构化数据的存储与管理。从分析空间数据的半结构化特征入手,以空间数据的嵌套关系为管理对象,实现了在关系型数据库中对空间半结构化数据的存储与管理。

This paper proposed to use object-relational database management systems to store and manage semi-structured Spatial data. ORA-SS（Object-Relationship-Attribute model for Semi-Structured data） was used as the data model. It not only reflected the nested structure of semi-structured data, but also distinguished between object classes and relationship types, and between attributes of object classes and attributes of relationship types.
