title: Oracle 11g Database Creation
body: <p>I am a newbie in Oracle databases and compared with my experiences with SQL Server and MySQL, Oracle is not as easy. Question is, when I tried to create a database using DB Configuration Assistant, when I look at the database using SQL Developer, there are already tables on it. Why does it have something like system tables on it if its a custom database. How can I instead put my own tables on that database.</p>
