本文将结合三峡散装水泥粉煤灰地秤称重子系统(以下简称三峡地秤称重系统)中工地地秤检测系统数据库与调度中心数据库的分布式异构数据库集成实施方案,探讨一种基于Powerbuilder的多层分布式应用系统的实现,并从实践中总结出分布式系统开发所要注意的问题。一、系统设计背景举
This article will combine the Three Gorges Bulk Cement Fly Ash Weighing Subsystem (hereinafter referred to as the Three Gorges scale weighing system) in the construction site scale detection system database and dispatching center database distributed heterogeneous database integration implementation plan to explore a based on Powerbuilder Multi-layer distributed application system, and summarizes the problems to be paid attention to in distributed system development from practice. First, the system design background cited
