Oracle課程設(shè)計(jì) 實(shí)驗(yàn)題目：倉庫管理系統(tǒng) 專 業(yè)： 計(jì)算機(jī)應(yīng)用與技術(shù) 班 級： 1440302 學(xué) 號：20110030226 姓 名： 胡強(qiáng) 指導(dǎo)教師： 王 芳一、系統(tǒng)描述倉庫管理系統(tǒng)的功能：1） 、產(chǎn)品入倉管理：在貨物送到倉庫時，對貨物信息進(jìn)行了解并將相關(guān)信息輸入到數(shù)據(jù)庫中，同時更新數(shù)據(jù)庫。2）、產(chǎn)品出倉管理：在貨物運(yùn)出倉庫時，進(jìn)行貨物信息統(tǒng)計(jì)并將數(shù)據(jù)保存到數(shù)據(jù)庫中，同時更新數(shù)據(jù)庫。3） 倉庫貨物信息提醒：當(dāng)貨物少于某一規(guī)定的值時，或者貨物保質(zhì)期將至?xí)r將發(fā)出提醒。4） 、借出管理：憑借條借出，然后能夠還庫。5）、查詢修改：管理員可以進(jìn)行一系列查詢：查詢貨物類別及貨物的信息、數(shù)量和貨物流動的規(guī)則（對貨物出倉進(jìn)倉的要求）；并可以對以上查詢進(jìn)行修改；可以查詢某一天貨物流動的信息，以及出倉及入倉的詳細(xì)信息。6）、初始化庫存設(shè)置：設(shè)置庫存的初始化值，庫存的上下警戒限制。7）、盤庫情況：反映沒有、年的庫存情況；二、系統(tǒng)需求分析利用用例圖、類圖、E-R圖對系統(tǒng)進(jìn)行需求分析。倉庫管理系統(tǒng)可以實(shí)現(xiàn)對倉庫貨物信息、出倉貨物管理、進(jìn)倉貨物管理、貨物數(shù)量管理以及貨物出入倉限制規(guī)則，以下為其用例圖、類圖及E-R圖。倉庫管理系統(tǒng)用例圖類圖表1：產(chǎn)品信息表PRO字段名數(shù)據(jù)類型長度約束說明PROIDNUMBER11主碼產(chǎn)品編號PRONAMEVARCHAR220NOT
