modeling的方式有很多種啦。傳統的data flow diagram就是focus在CRUD這個層面。再配合data modelig,就可以搞定所有跟db有關的analysis & design。對於一個db centric的系統來說,這兩個東東是開發這類型系統免不了的。

至於Use Case的話,這個東西好像拿來開發non-db centric的program比較適合。如果你的系統有很複雜的user - computer interaction的話,用use case就粉適合。

有些人希望用object的方式把db的東西包起來,想說要節省開發的時間,這個世界就有了一種叫做entity bean的東東,可是又有人嫌entity bean的performance太差,我想update一個小小的欄位,哇勒懶惰的programmer就整陀東西從db讀過來,再寫回去。勤快的programmer就想要直接下sql command,就有另外一個叫做DAO的東西。(偶是聽來的,現在也忘得差不多了,詳情偶就不了啦。錯了完全不負責。Smile在這個論壇,不會java還可以話唬爛的,我應該算是箇中翹楚。)

A...至於你要的,是use case的標準model? 還是design的標準model呢?還是你要的是怎麼樣去implement這個東東呢?因為j2ee, struts好像都跟analysis, design該怎麼做無關啊。Smile你文章的第二段跟第三段接不在一塊兒呀。Big Smile
