工程勘察信息系统中多S集成应用研究

Study on Multi-S Integration Application in Engineering Exploration Information System

大型工程勘察信息系统的开发需要运用多项现代化高新技术系统，其中包括数据 库系统（DBS）、地理信息系统（GIS）、计算机辅助设计系统（CADS）、遥感信息处理系 统 （RS）和全球卫星定位系统（GPS）以及专家系统（ES）等。提高系统的应用价值关键是 进 行多S集成。在实践的基础上该文指出系统集成包括数据集成和操作集成两个方面的内容 ， 提出并对比了中间文件模式、基于COM的模式以及系统平台模式等几类集成模式。举例说 明 了开发者在点源信息系统理论指导下可以根据不同情况选择系统集成的层次和模式。

Development of large scale engineering exploration information syste m needs support of many modern hi-tech systems, such as database system, geogra p hic information system, computer-aided design system, remote sensing system, g lo be positioning system and expert system. Implementation of multi-S integratio n i s key to improve the importance of the information system. Based on the prac tice , it is indicated in this paper that system integration includs data integr ation and operation integration, and it also puts forward and compares middle f ile mo del, COM-based mode and system platform mode, etc. With examples it has been ex plained that developer could select different system integration level a nd diffe rent integration mode according to different case under the instruction of theor y of point-source information system.
