The Research Methods and Techniques of Spatial Analysis Databases

通过大量文献研究 ,分析了空间分析数据库的研究平台、研究方法和技术 ,以及各种研究平台的优缺点 .重点讨论了基于 Realms的空间数据类型、ROSE代数、基于可扩充 DBMS的空间分析数据库的研究方法和技术 ,以及同类系统的不足和需研究解决的问题 ,并指出 Realm s可以有效地表示二维的空间数据及支持空间拓扑操作算法 .文中还分析研究了基于主存数据库技术和 ROSE代数的空间存储管理子系统 ,并指出把它与可扩充数据库管理系统或具有 ADT机制的 DBMS进行集成 ,是研究空间分析

This paper analyses the research platforms, methods and techniques of spatial analysis databases, as well as the advantages and disadvantages of various research platforms. And it discusses emphatically the spatial data types based on the Realms, ROSE algebra, and the research methods and techniques of spatial analysis databases based on extensible DBMS as well as the disadvantages and problems of the systems based on the principles. The Realms can be used to represent spatial data of two dimensions and to implement the spatial topological algorithms efficiently. First, the spatial subsystem based on the techniques of main memory databases and the ROSE algebra is designed and implemented. Then it is integrated into extensible DBMSs, or DBMSs with the ADT mechanism. And it is an efficient approach to develop spatial analysis database management systems.
