title: How to create a new database after initally installing oracle database 11g Express Edition?
body: <p>I have installed Oracle Database 11g Express Edition on my pc (windows 7)
  and I have installed Oracle SQL Developer as well. </p>
  
  <p>I want to create a simple database to start with, maybe with one table or two and then use Oracle SQL Developer to insert data and query it.</p>
  
  <p>When I open Oracle SQL Developer, it asks me to create a new connection, therefore it assumes that a database has already been created. </p>
  
  <p>So my question is, how do I create an initial database in Oracle 11g?</p>
