Head First Object-Oriented Analysis and Design
這一本深入淺出物件導向分析設計（中文版）是最近在看的書，真的非常深入淺出，我一個下午就看了快400頁，當然像當故事這樣看很快，有時候才會對內容注意一下：
因為最近在準備SCJP所以對Attribute（屬性）跟Operation（操作）就比較注意，看了這個連連看得答案就覺有問題，我倒是認為Attribute應該是連Equivalent to a member variable in a class（等同於類別裡的成員變數），Operation是連This is the UML term that usually represents a method in one of your classes.（這是UML的術語，通常代表類別裡的方法）。
各位覺得如何？

此書已絕版，無法購買，只能從圖書館借閱，有找到【深入淺出物件導向分析與設計】第一章、偉大軟體由此開始的分享，也是用C#語言實作，或許改天可以問他看看，如果朋友有深入淺出物件導向分析與設計pdf的話，可以分享一下，謝謝！
這裡轉錄一下他紀錄的心得：
情境
客戶：Rick 的亂彈吉他店
需求：建立吉他庫存管理應用程式，並提供搜尋功能，為客戶配對心目中的理想吉他。
廠商：「低階編程」軟體公司
顧客：Erin (來到 Rick 的店尋找心目中理想的吉他)
版次：v0.1

現在要找到中文版的深入淺出物件導向分析與設計pdf好像不好找，如果有朋友有的話，請留言給我，謝謝！
目前各位還是可以先到圖書館去借閱
