摘要
针对网络环境和异构数据对WebGIS的体系及功能提出的新要求,分析了J2EE架构和ArcGIS开发平台的特点,采用J2EE多层分布式应用模式和ArcGIS平台构建了一个测绘成果管理系统,该系统具有很好的可维护性和可扩展性,可方便地实现组件的复用、组装.详细介绍了系统的数据库设计、总体架构设计以及功能模块设计;在系统实现部分介绍了利用EJB组件技术实现测绘成果空间信息发布和非空间信息维护的实现过程.
The environmental changes in network and the existence of heterogeneous data bring new requirements for the architecture and functions of WebGIS,with a sum up of the background of J2EE and ArcGIS,the J2EE multi-tier distributed application model and ArcGIS platform were adopted to build an information management system of the survey and mapping production,which is very maintainable and extendable and can conveniently realize reuse and assembly of software components.Then the system＇s database design,overall architecture and function modules were discussed;and implementation method of the spatial information publishing and non-spatial information maintenance using EJB component technology was introduced in detail.
