1、《圖書管理系統(tǒng)》系統(tǒng)設(shè)計報告 一、 引言 1． 摘要：中學(xué)圖書館管理系統(tǒng) 目的：方便圖書館對書籍借閱的管理 主要功能： —學(xué)生基本信息查詢 —書籍借閱管理 —書籍管理 2． 背景：第十小組承擔(dān)開發(fā)任務(wù) 3． 工作條件與限制：windows操作平臺，Visual Basic6.0和SQL Sserver2000等軟件為開發(fā)工具，利用上課時間和課外時間做成。由于現(xiàn)在圖書管理系統(tǒng)已經(jīng)比叫完善，所以我們暫時沒有能做出比以前有先進技術(shù)的管理系統(tǒng)。 4． 參考和引用資料：《數(shù)據(jù)庫系統(tǒng)概論》，VB應(yīng)用 5． 專門術(shù)語定義： 二、系統(tǒng)總體技術(shù)方案 1． 計算機

2、系統(tǒng)配置：windows平臺，VB/SqlServer2000，WINNT SERVER操作系統(tǒng), SQL server2000關(guān)系數(shù)據(jù)庫管理系統(tǒng) ，VB操作軟件，局域網(wǎng)。 2． 模塊設(shè)計：主要分為三個模塊：即學(xué)生基本信息模塊，書籍借閱模塊，書籍管理模塊 代碼設(shè)計：讀者信息查詢 Public connStr As ADODB.Connection Private Sub Command1_Click() End Sub Private Sub cmdAdd_Click() If Trim(List1.Text) <> "" Then List2.AddI
