| Abstract: | Integrated storing and accessing geographical features related information is one of the most important technologies for GIS application developments. It has been a consensus of opinion in the GIS society that storing and managing mass spatial data with current business relational database management systems under the support of extended relational models is an efficient and effective technology for developing mass data and network oriented spatial database management systems. In this paper, the authors analyzed and discussed some typical spatial database management platforms including ArcSDE, Oracle Spatial, Informix Spatial DataBlade, DB2 Spatial Extender and MySQL Spatial Extensions from the view of storing models, process management schema, spatial querying and indexing, and data cache approaches. It is argued that current business spatial data engines or extension technologies still deserve much more research and improvements, especially for topology representation within relational database management systems and application schema, adaptive spatial indexing and optimization methods, and user defined complex object representation, sharing and inter-operability. |
