地理特征相关信息的一体化存储与访问是Gls软件平台研发的关键技术。在扩展关系数据模型的支持下，利用成熟的商用扩展关系型数据库管理系统存储和管理海量空间数据，是发展大型GIS平台空间数据库管理系统行之有效的技术方法。本文对几种典型的空间数据库管理平台ArcSDE、oracle Spatial、Informix Spatial DataBladeDB2 Spatial Extender和MySQL Spatial Extensions从存储模型、进程管理方案、空间查询和索引以及数据缓存技术等方面进行了分析。 |

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 ori-ented 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 represen-tation within relational database management systems and application schema, adaptive spatial indexing and op-timization methods, and user defined complex object representation, sharing and inter-operability. |
