1、數據庫程序設計大作業班級：2012級軟件外包服務一班學號：201215140117姓名： 。時間：2013-6-19 1功能描述1.1 功能簡介用swing做出圖形化界面形式，實現數據庫的增刪改查把員工表跟部門表連接起來，實現數據的增加，刪除，修改，查找。1.2 實現步驟（1）安裝好虛擬機，并在其下確認oracle已安裝成功（可以在dos下輸入相關命令來檢查是否安裝成功）。（2）在網絡中心修改pc機上的VMware Network Adapter的IP、子網頁碼（默認）、網關。（3）修改虛擬機的IP、網掩碼（默認）、網關，確保PC機上的網關和虛擬機的IP一致。（在控制面板>網絡和共享中心

2、>本地連接3>屬性中，修改IP、網掩碼）（4）在PC機的dos命令控制臺ping虛擬機的IP，確保正常，能ping通（即將虛擬機內外ping通）。（5）配置好虛擬機下的oracle的數據庫和監聽。（6）在eclipse中編寫相關代碼，并用jtable實現圖形化界面，用以實現與數據庫的連接和操作數據庫等功能。（7）在eclipse中導入數據庫的驅動。（8）運行eclipse，查看運行結果。2. 核心代碼2.11. 數據庫連接package .dbc;import java.sql.Connection;import java.sql.DriverManager
