ArcSDE Service在数据库与GIS平台数据交互中的应用

ArcSDE Service's application of data interaction between database and GIS platform

ArcSDEservice是空间数据引擎ArcSDE3层架构的中间层,担负着在客户端与服务器数据交互的重要任务。介绍了ArcSDEservice的相关概念,分析了ArcSDEservice的两个重要进程giomgr进程和gsrvr进程的工作过程,阐述了ArcSDEservice的工作原理。通过ArcSDEservice,实现了存储于Oracle数据库的浙江省海岸带遥感数据与ArcGIS平台的交互,认为ArcSDEservice的应用较好地解决了GIS应用与空间数据库集成中数据提供与访问模式方面的制约瓶颈问题,是一种比较可行的方案。

As the middle layer of three-tiered structure of spatial data engine-ArcSDE, ArcSDE service is responsible for data interaction between client and server. Properties of ArcSDE service were introduced. The working procedure of giomgr and gsrvr processes were analyzed and the working principle of ArcSDE service was expounded. Utilizing ArcSDE service, interaction between GIS data in Oracle and ArcGIS platform was realized. The application of ArcSDE service resolved bottleneck of data provided and data access model between GIS application and DBMS.
