程序健壮性设计

The Procedure Haleness Design

程序健壮性是任一款软件追求的主要目标之一。当需求功能达到后,美观是一个方面,可靠、健壮是更重要的另一方面。而设计者与编程人员可能往往因为任务紧迫而忽略后者。这样给维护带来一系列的麻烦。一旦软件交付使用,维护费用可能成倍增长。所以在编程一开始就设计出一套自己的应急部分是十分必要的。以Delphi开发环境为例,演示了陷阱处理机制及几种辅助工具在程序健壮性设计中的使用方法。

The procedure haleness is one of the main targets of any style software. When the need function attain after, the beauty interface is one side,credibility and the haleness is more important on the other hand. But the designer and the programmer may usually neglect the latter because the project is urgent. It brings a series of trouble to the software maintenance. Once the software consigns a usage, support expenses would become a fast growth. It is very necessary to design a set of meet an emergency part only at beginning. The article takes the Delphi development environment as an example, playing to tra Pprocessing mechanism and to operate method of several assistance tools in the procedure haleness design.
