      四、 認識Access2003的數據庫對象

      1.  表
      是Access 2003存儲數據的地方,是數據庫的核心和基礎
        
      2.查詢
       可以按照不同的方式查看、分析和更改數據

      3.窗體
           數據庫和用戶之間的主要接口

      4.報表
            把數據庫中的數據打印輸出的特有形式

      5.頁
           頁也稱為數據訪問頁
      6.宏
        由一系列操作組成,能自動執行一些任務
      7.模塊
        用VBA語言編寫的程序段

      五、 上機操作

      1、使用數據庫模板向導新建數據庫

      操作提示:
      (1)首先啟動Access,然后依次單擊:新建文件/本機上的模板→數據庫/聯系人管理→確定→數據庫文件保存位置:你的文件夾名,文件取名:“聯系管理.mdb”→ 創建 → …(按照向導提示,一步一步進行…,直到完成“聯系管理”空數據庫的創建并保存在你的文件夾中)。
      (2) 建立聯系人表:
      1)打開剛才創建的“聯系管理.mdb”(會打開“主切換面板”);
      2)利用“主切換面板”上的“輸入/查看聯系人”命令,輸入聯系人的數據記錄,建立聯系人表。字段、內容如下:
       
      姓氏 名字 昵稱 地址 城市 省份 郵政編碼 地區 國家 公司名稱 頭銜 工作電話 工作分機
      張三 老三 上下九路 12號 廣州 廣東 510020   中國 公司A 科長 87878828 263
      李四 老四 北京路32號 廣州 廣東 510260   中國 公司B 班長 23247838 456
      王五 老五 黃花路 128 號 廣州 廣東 510246   中國 公司C 副經理 28384858 246
      黃六 阿六 中山路 34 號 天津 河北 510002   中國 公司D 副董事長 88775462 001
      3)瀏覽此數據庫對象(表、查詢、窗體、報表等)。退出“主切換面板”。
       

      2、創建學生管理數據庫

      (1)在你的文件夾下創建一個新的空數據庫,取名為“學生管理.mdb”。
      (2)在“學生管理.mdb”中通過輸入數據創建“學生成績”表,其字段名稱依次為:學號、成績、開課序號、學分,按下方表格中的數據排列輸入數據,完成后數據表視圖如圖1所示。完成后保存并關閉數據表視圖。
       
      20020201 89 1-10 2
      20020201 98 2-10 2
      20020202 61 2-10 2
      20020202 97 1-10 2
       
       
       
       
       

      圖1
       
      (3)在“學生管理.mdb”中用數據表設計器按如下字段信息創建“社會關系”表:該表有字段名稱、類型和屬性,無記錄。
      字段名稱 數據類型 字段大小(bytes)
      學號 文本 16
      家長姓名 文本 8
      家庭住址 文本 10
      聯系電話 文本 20
       
       

      3、在“學生管理”數據庫中進行如下操作:

      (1)查詢李林同學的基本信息(顯示“學生檔案表”中李林同學的記錄)查詢結果如所示。
      2
      (2)創建瀏覽課程信息窗體(窗體可以滾動顯示“課程名”表中的所有記錄),窗體樣式如圖3 所示。

      3
      (3)創建課程信息報表。報表樣式如圖4所示。
