1.項(xiàng)目需求分析

javaWeb增強(qiáng)：

過濾器、監(jiān)聽器、國際化、文件上傳與下載、JavaMail郵件開發(fā)

回顧項(xiàng)目開發(fā)設(shè)計(jì)模式之mvc模式：

M model 模型層【entity/dao/service】

V view 視圖層【jsp/html…】

C control 控制器【servlet】

優(yōu)缺點(diǎn)：

每一層各司其職！更容易更換具體的實(shí)現(xiàn)，而對(duì)其他層代碼影響較??！

目標(biāo)：

1. 掌握mvc開發(fā)模式

2. 需求分析

《需求分析說明書.doc》

3. 設(shè)計(jì)數(shù)據(jù)庫

每一組用同一個(gè)數(shù)據(jù)庫。

4. 編碼

組長：分配任務(wù)，每個(gè)人要做什么 (項(xiàng)目計(jì)劃)

項(xiàng)目開發(fā)生命周期

軟件項(xiàng)目開發(fā)模式：

螺旋開發(fā)模式

適合于項(xiàng)目前期部分需求不確定的情況，對(duì)于每一個(gè)模塊一個(gè)個(gè)開發(fā)：分析、設(shè)計(jì)、編碼、測試、上線；

好處：降低軟件風(fēng)險(xiǎn)！ (做出的產(chǎn)品要盡量滿足客戶需求！)

瀑布模式:

先進(jìn)行所有模塊的需求分析，當(dāng)分析結(jié)束后，才進(jìn)入項(xiàng)目下一個(gè)階段，即設(shè)計(jì)、編碼、測試、上線；

好處：更容易進(jìn)行項(xiàng)目把控，即項(xiàng)目質(zhì)量控制！

需求分析：

軟件工程師：了解需求的途徑？

1. 需求文檔

2. 項(xiàng)目經(jīng)理

3. 項(xiàng)目的系統(tǒng)原型 (美工設(shè)計(jì)師)

4. 客戶

“餐館王”系統(tǒng)功能：

1. 餐桌模塊

2. 菜類別模塊(菜系)

3. 菜信息 (菜品)

4. 訂單

詳細(xì)分析：

1. 后臺(tái)錄入的餐桌，要在前臺(tái)首頁顯示；且只顯示未預(yù)定

2. 后臺(tái)錄入的菜類別，在前臺(tái)主頁顯示

3. 后臺(tái)錄入的菜信息，在前臺(tái)主頁顯示

4. 前臺(tái)生成訂單后，在后臺(tái)顯示訂單詳細(xì)

2.數(shù)據(jù)庫設(shè)計(jì)

-- 創(chuàng)建數(shù)據(jù)庫
