基于Delphi的多层结构安全稳固技术的实现

The Achievement of Safety and Firmness in Multi - tier Architecture based on Delphi

传统的二层客户/服务器结构在大规模MIS应用中表现出许多局限性,为此多层结构应用体系应运而生,多层结构已成为目前分布式系统的主要应用结构。其安全稳固问题一直受业界关注。阐述了3种基于Delpbi的多层结构安全稳固技术(容错技术、负载平衡技术、暂存数据技术)的原理,并给出了程序实现代码。

Two - tier architecture has many defects in application of large MIS, so Multi - tier architecture comes into being. Multi - tier architecture is one main structure of distributed system at present. Many people always pay attention to its issue of safety and firmness. This paper introduces three safety and firmness principles of Multi - tier architecture based on delphi and presents its program code.
