因为她开始于她的草稿代码，因此我们需要返回她的设计到我们的模型中。
Because she had started from scratch with her code, we needed to back her design into our model.
在此步骤中，我们主要尝试应用分析和设计模式，使模型形式更加良好，从而增加重用潜力。
In this step, we mainly try to apply both analysis and design patterns to make the model better formed that would increase its potential for reuse.
为了更好地理解这两个模型之间的差异，我们来看看每个模型如何影响应用程序的设计和实现。
In order to better understand the differences in the two models, let's look at how each model impacts an application design and implementation.
