设计模式在报名系统中的研究与应用

设计模式理论提出软件系统的质量可以客观地衡量,它更好地展现了面向对象的设计原则,是更为优秀的面向对象设计方法.设计模式能避免传统的面向对象设计方法中存在的不足,如高耦合、低内聚、适应需求变化能力差等问题.本文首先介绍了设计模式的概念、要素和使用的必要性,然后通过一个培训报名系统实例,主要给出了其中命令模式的分析与应用,同时指出不同的设计模式可适用于不同的场合.

The Application of Design Pattern to Reception System

The theory of design patterns put that the quality of the software can be objectively measured. It shows the principles of object - oriented design better and it is a more excellent way of object - oriented design. Design patterns can avoid the inadequacy of the traditional object - oriented design methods, such as high coupling, low cohesion, poor ability to adapt to needs changing. The article introduced the concepts and elements of design patterns, and the necessity to use. Then through a training reception system as an example, which gives the analysis and application of the code model mainly, while noting the different design patterns applied to different occasions.
