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.
