建立高效运行海量空间数据库的策略与方法

The Maneuver and Method of Establishing Efficiently Running Magnanimity Spatial-database

以建设江苏省基础地理信息数据库的实践为基础 ,反复比较不同参数、方法对数据库运行性能的影响 ,探讨了提高海量空间数据库检索和显示效率的技术方法和相关参数选取原则 。

This paper which is based on the practice of establishing Jiangsu foundational Geographical information database, compares different influence which caused by parameters and methods impact on the database, discusses the technical methods which can improve the indexing of the magnanimity spatial-database and the displaying efficiency,ensure the rules by which we can choose mutual parameters, then concludes some maneuvers and methods which can optimize the spatial-database.
