%X Techniques needed in the management of distributed spatial databases are discussed, abilities of distributed management in the commercial software Oracle and ESRI products are described, and a practical methodology to build distributed spatial applications is suggested. In a distributed spatial database, there is usually a main server and many data servers, and all of them are linked by networks such as internet. In order to guarantee the normal data flow and analysis among clients, main server and data servers, issues of net communication, metadata management, data consistency, data serving, spatial data search engine, seamless data integration, quick updating, data transfer, data queuing and security protection should be solved. Oracle and ESRI series products can act as frames in distributed spatial database management applications, and the performance will be much better if some key components can be developed from bottom.
