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.
