My first Database in Oracle 9

Often I puzzled with creating own database in oracle. Mysql was pretty easier, but how big step it is in oracle!
Also, here is code for asccessing newly created db: (using jdbc)

---------
Properties props = new Properties();
props.put("user", "scott");
props.put("password", "tiger");
props.put("internal_logon", "sysdba");
Connection conn = DriverManager.getConnection (url, props);
