9.access由于access并不是作为一项服务运行，所以url的方法对他不适用。access可以通过odbc，也可以通过服务器映射路径的形式找到.mdb文件,参见http://rmijdbc.objectweb.org/Access/access.html

JDBC API的使用方法
(1)登记并加载JDBC驱动程序；
两种方法：
Class.forName(String drivername);
DriverManager.registerDriver(Driver driver)

(2)建立与SQL数据库的连接；
DriverManager的getConnection()方法：
Connection getConnection(String url):url表示数据库地址字符串；
Connection getConnection(String url,String user,String pwd)
Connection getConnection(String url,Properties info)
(3)传送一个SQL查询；
Connection的createStatement()方法：
Statement createStatement();
Statement可以执行SQL语句，得到SQL查询结果。

(4)获得结果集。
Statement的执行SQL语句方法：
ResultSet executeQuery(String sql):执行select语句
int executeUpdate(String sql)：执行更新语句，如insert,delete,update.

(5)检索查询结果。
ResultSet的方法：
boolean next():没有行时返回false;
String getString(String columnName)：返回列名对应的值。
