设计模式在架构设计中的运用

软件架构经常不能适应变化，程序员也经常觉得架构没什么用。分析引起软件架构变化的形式，可以归结为组件间交互接口和编码实现的变化；共分为4种：1）相似接口，相同功能；2）不同接口，相似功能；3）增替“实现”；4）精简接口。根据不同的变化情景，运用合适的设计模式就能提高架构的适应性；同时，对程序员也更具指导意义。

Design Patterns in Architecture Design

Software architecture often can not adapt to the changes, and programmers often think that the software architecture is useless. Analysis the form of software architecture＇s evolution, can be attributed to the interactive interface between components and realize the changes in coding; divided into four kinds： 1） Similar interface, the same function; 2） Different interface, similar functions; 3） Add or replace the codes; and 4） Streamline interfaces. According to different situations, the use of appropriate design patterns can improve the adaptability of the architecture; at the same time, programmers receive more guidance.
