??? Oracle的空間數(shù)據(jù)庫(kù)的操作驅(qū)動(dòng)更新了，新的驅(qū)動(dòng)適用于Oracle8.0或以上，新驅(qū)動(dòng)在對(duì)數(shù)據(jù)庫(kù)的操作上面和原有的驅(qū)動(dòng)差別比較大，不過(guò)有一點(diǎn)：使用變得簡(jiǎn)單了
??? 建立空間數(shù)據(jù)庫(kù)和建立空間索引的步驟就略過(guò)了，那些網(wǎng)上有很多例子，而且實(shí)現(xiàn)方式上面也沒(méi)有變化，下面列出添加一條空間數(shù)據(jù)庫(kù)記錄的代碼：
import java.sql.*;
import oracle.sql.*;
import oracle.spatial.geometry.JGeometry;
