摘要
针对MapX组件在管理地理信息时空间数据与属性数据相分离、数据管理及查询效率不高的问题,通过引入OracleSpatial空间数据管理技术,实现了属性数据和空间数据的一体化存储与管理。利用空间操作符进行空间邻近分析,提高了系统的稳定性和数据的查询速率,并针对空间数据转换时造成的信息丢失问题提出解决方法。该技术方案在航油公司EAM(enterprise asset management)系统中得到应用,并取得较好效果。
When geographic information is managed by MapX component, spatial data and attribute data are separated and the efficiency of data query is not high. Based on the technology of Oracle spatial, the integration storage and management are implemented. At the same time, by use of space operators to the proximity analysis, the efficiency of spatial data query is improved, and an effective solution is proposed for preventing information lost in the process of spatial data conversion. Finally, the program is applied to the EAM （enterprise asset management） system of the aviation oil company and obtained good performance.
