摘要
解决用户应用系统与空间数据库间的数据传输成为空间数据库能否得以充分利用的关键问题。在众多解决方案中,空间数据库引擎备受关注。本文对几种常见的空间数据引擎ArcSDE、OracleSpatial、SpatialWare、DB2SpatialExtender和ImformixSpatialDataBlade以及SuperMapSDX+,从存储模型、进程管理、空间查询与索引、数据缓存技术以及二次开发等方面进行了分析。
Data transmission between the Spatial Database and user＇s application systems becomes the primary problem. Whether Spatial Database can be used sufficiently depends on how much this problem can be coped with. In many solutions, Spatial Database Engine （SDE） attracts much more attention. In this paper, the authors analyzed and discussed some typical spatial database management platforms including ArcSDE, Oracle Spatial, SpatialWare, DB2 Spatial Extender, lmformix Spatial DataBlade and SuperMapSDX ＋ from the view of storing models,process management schema,spatial querying and indexing,and data cache approaches.
