## 第2章 用隱喻來更充分的理解軟件開發 　 ### 中文要點： - 隱喻是啟示而不是算法.因此它們往往有一點隨意(sloopy). - 隱喻把軟件開發過程與其他你熟悉的活動聯系在一起,幫助你更好的理解. - 有些隱喻比其他一些隱喻更貼切. - 通過把軟件的構建過程比作是房屋的建設過程,我們可以發現,仔細的準備是必要的,而大型項目和小型項目之間也是有差別的。 - 通過把軟件開發中的實踐比作是智慧工具箱中的工具，我們又發現，每位程序員都有許多工具，但并不存在任何一個能適用于所有工作的工具，因地制宜的選擇正確工具是成為能有效編程的程序員的關鍵。不同的隱喻彼此并不排斥，應當使用對你最有益處的某種隱喻組合。 ### English Key Points： - Metaphors are heuristics, not algorithms. As such, they tend to be a little sloppy. - Metaphors help you understand the software-development process by relating it to other activities you already know about. - Some metaphors are better than others. - Treating software construction as similar to building construction suggests that careful preparation is needed and illuminates the difference between large and small projects. E Thinking of software-development practices as tools in an intellectual toolbox suggests further that every programmer has many tools and that no single tool is right for every job. Choosing the right tool for each problem is one key to being an effective programmer.
