Abstract

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.
