PAGEPAGE2宿舍管理系統(tǒng)緒論1.1引言該系統(tǒng)是由管理員通過(guò)系統(tǒng)管理學(xué)生信息，能根據(jù)學(xué)生學(xué)號(hào)、院系、寢室號(hào)等來(lái)查詢學(xué)生的其他相關(guān)信息，新生入住能錄入新生的住宿信息，能查詢房間的信息如入住人數(shù)、人員、費(fèi)用等。學(xué)生遇畢業(yè)退學(xué)等原因能刪除其住宿信息，同時(shí)，備忘一些信息，記錄非寢室住宿人員的出入登記，并能進(jìn)行查詢相關(guān)登記記錄。系統(tǒng)采用java語(yǔ)言編寫，利用功能強(qiáng)大的myeclipse作為開發(fā)工具，用數(shù)據(jù)文件存儲(chǔ)數(shù)據(jù)。1.2系統(tǒng)模塊用戶登錄模塊學(xué)生信息查詢模塊學(xué)生信息添加模塊房間查詢信息模塊1.3設(shè)計(jì)思想根據(jù)初步對(duì)宿舍相關(guān)信息的了解的進(jìn)行設(shè)計(jì)1.4系統(tǒng)框架采用.netframework3開發(fā)類庫(kù)中windowsForm窗體應(yīng)用程序，作為系統(tǒng)框架，在myeclipse開發(fā)環(huán)境中，利用各個(gè)控件，進(jìn)行相關(guān)模塊的設(shè)計(jì)，在系統(tǒng)中進(jìn)行對(duì)數(shù)據(jù)的一些基本操作。2.0設(shè)計(jì)步驟2.1．簡(jiǎn)要描述題目要求，對(duì)問題的描述應(yīng)避開算法及所涉及的數(shù)據(jù)類型，只是對(duì)所需完成的任務(wù)做出明確的陳述，例如輸入數(shù)據(jù)的類型、值的范圍以及輸入的形式，輸出數(shù)據(jù)的類型、值的范圍以及輸出的形式。2．2選定數(shù)據(jù)結(jié)構(gòu)，寫出算法，根據(jù)自頂向下發(fā)展算法的方法，首先描述算法的基本思想，然后進(jìn)行算法細(xì)化，再對(duì)所設(shè)計(jì)的算法的時(shí)間復(fù)雜性和空間復(fù)雜性進(jìn)行簡(jiǎn)單分析。2．3準(zhǔn)備好上機(jī)所需的程序，選定一種程序設(shè)計(jì)語(yǔ)言（如C語(yǔ)言），手工編好上機(jī)程序，并進(jìn)行反復(fù)檢查，使程序中的邏輯錯(cuò)誤和語(yǔ)法錯(cuò)誤減少到最低程度。對(duì)程序中有疑問的地方，應(yīng)做出標(biāo)記，以便在上機(jī)時(shí)給予注意。2．4上機(jī)輸入和調(diào)試程序，在調(diào)試程序過(guò)程中除了系統(tǒng)的問題以外，一般應(yīng)自己獨(dú)立解決。在程序調(diào)試通過(guò)后，打印輸出程序清單和運(yùn)行結(jié)果。2．5上機(jī)結(jié)束后，總結(jié)和整理實(shí)驗(yàn)報(bào)告。2.6系統(tǒng)設(shè)計(jì)2.6.1學(xué)學(xué)生管理查找添加修改2.6.2StudentMessage.txt.4系統(tǒng)E-R圖為學(xué)生——寢室學(xué)生學(xué)生學(xué)號(hào)姓名寢室號(hào)學(xué)生——寢室——訪人第三章總體設(shè)計(jì)3.1需求規(guī)定輸入輸出要求界面風(fēng)格：要求整體界面美觀，有清晰的層次感，布局簡(jiǎn)潔、合理。時(shí)間要求時(shí)間需求:在軟件方面，響應(yīng)時(shí)間，更新處理時(shí)間都比較快且迅速，系統(tǒng)響應(yīng)時(shí)間不能超過(guò)10秒。靈活性要求靈活性:當(dāng)用戶需求，如操作方式，運(yùn)行環(huán)境，結(jié)果精度，數(shù)據(jù)結(jié)構(gòu)等其他軟件接口等發(fā)生變化時(shí)，設(shè)計(jì)的軟件能做出適當(dāng)調(diào)整，靈活性非常大3.2基本設(shè)計(jì)概念神處理流程3.3系統(tǒng)出錯(cuò)處理出錯(cuò)情況系統(tǒng)輸出信息含義處理方法用戶名密碼為空“用戶名或密碼為空，請(qǐng)重新輸入”用戶名或密碼為輸入輸入，不能為空用戶名密碼錯(cuò)誤“用戶名或密碼錯(cuò)誤”輸入的登錄數(shù)據(jù)與數(shù)據(jù)庫(kù)不匹配重置后重新輸入查詢出錯(cuò)“請(qǐng)確認(rèn)輸入信息無(wú)誤”未能找到有關(guān)信息或查詢的關(guān)鍵字輸入錯(cuò)誤清空后重新輸入添加出錯(cuò)“數(shù)據(jù)有沖突”添加數(shù)據(jù)時(shí)違反了數(shù)據(jù)庫(kù)中的主鍵，添加了重復(fù)的數(shù)據(jù)3.4系統(tǒng)主要模塊的界面設(shè)計(jì)界面主要含有兩個(gè)部分，登錄界面和主頁(yè)面，登錄界面用于用戶登錄到主頁(yè)面去，登錄到主頁(yè)面后，進(jìn)行各項(xiàng)操作3.4.1mb1.setLayout(null);
