【摘要】 在介绍网络系统集成方法的基础上 ,重点讨论了多数据库系统与网络集成系统各自的结构特点。理论分析与住宅小区集成系统的建设及运行实践证实 ,采用“自上而下”的设计方法 ,建设满足全局需求的相对稳定的全局数据库系统 (GDBS) ,并通过接口管理器所控制的子系统与GDBS之间的接口为GDBS提供数据而组建的网络集成系统 ,对中小型网络集成系统的建设 ,技术、经济和系统性能等方面都具有较好的可行性更多还原

【Abstract】 Based on the introduction of network system integration technique, we discuss the structure features of multi database system and integrated network system. Through theoretical analysis and system implementation, we find the following design approach is feasible in technology,suprior in system performance, and economic in funds for middle small network integratoin system:constituting a steady global database system with "Top to Down" procedure; providing data to the globaldatabase system with the interface controller between it’s subsystems and the global database system.更多还原
