JAVA-連接sqlserver-學(xué)生成績(jī)管理系統(tǒng)-DOC(共21頁(yè))

1、學(xué)生成績(jī)管理系統(tǒng)課程設(shè)計(jì)實(shí)驗(yàn)報(bào)告題 目 學(xué)生成績(jī)管理系統(tǒng) 學(xué) 院 數(shù)學(xué)與信息工程學(xué)院 專 業(yè) 計(jì)算機(jī)科學(xué)與技術(shù) 班 級(jí) 同組成員 編寫日期 一、 課程設(shè)計(jì)目的 做這個(gè)小的學(xué)生成績(jī)管理系統(tǒng)來(lái)加深對(duì)JAVA所學(xué)知識(shí)的鞏固，以及學(xué)習(xí)JAVA與數(shù)據(jù)庫(kù)的連接和JAVA的GUI圖形界面。二、 需求分析此系統(tǒng)實(shí)現(xiàn)如下系統(tǒng)功能：（1）使得學(xué)生的成績(jī)管理工作更加清晰、條理化、自動(dòng)化。（2）通過(guò)用戶名和密碼登錄系統(tǒng)，查詢學(xué)生基本資料，學(xué)生所學(xué)課程成績(jī)，等功能。 容易地完成學(xué)生信息的查詢操作。(3) 設(shè)計(jì)人機(jī)友好界面，功能安排合理，操作使用方便，并且進(jìn)一步考慮系統(tǒng)在安全性，完整性，并發(fā)控制，備份和恢復(fù)等方面的功能要

4、多內(nèi)容，在此基礎(chǔ)上，對(duì)JAVA的基礎(chǔ)知識(shí)得到了更好的鞏固。在制作的過(guò)程中我也學(xué)到很多思想：首先，要學(xué)會(huì)統(tǒng)籌全局，合理規(guī)劃，例如在制作整個(gè)框架的時(shí)候提前就要做全面考慮，要把整個(gè)結(jié)構(gòu)圖畫出來(lái)，并且要對(duì)數(shù)據(jù)庫(kù)表里的東西做全面規(guī)劃。同時(shí)在編寫程序的時(shí)候也要想好先實(shí)現(xiàn)什么功能，再實(shí)現(xiàn)什么功能，這樣做出來(lái)的東西才有條理性，更容易實(shí)現(xiàn)和理解。其次，要細(xì)心仔細(xì)。Java程序雖然容易理解，但在寫的過(guò)程中一不留心就會(huì)出現(xiàn)錯(cuò)誤。當(dāng)然出錯(cuò)是在所難免的，與性質(zhì)有關(guān)的錯(cuò)誤可以經(jīng)過(guò)思考討論后進(jìn)行改正，但如果粗心大意，出現(xiàn)輸入上的錯(cuò)誤就很難發(fā)現(xiàn)和修改，會(huì)耽誤很多時(shí)間。我認(rèn)為最大的收獲是提高了自己的動(dòng)手能力。在平時(shí)的上機(jī)中大多

5、數(shù)是根據(jù)書上的思想和布局來(lái)寫程序的。這次的課程設(shè)計(jì)要自己思考自己寫，考慮的東西比平時(shí)上機(jī)考慮的要多的多。在整個(gè)設(shè)計(jì)過(guò)程中寫代碼不是最難的，最難的是構(gòu)思和布局。這次課程設(shè)計(jì)也是一次很好的實(shí)踐活動(dòng)，讓我們體會(huì)到了java的神奇作用。附錄：源代碼1、用戶登錄界面import java.awt.*;import javax.swing.*;import java.awt.event.*;import java.sql.*;public class Systems extends JFrame implements ActionListenerstatic Systems ss;JPanel panel
