title: Taking backup of Database in Oracle 10g Express edition
body: <p>I have tried a lot but have always failed to get the backup of the database in Oracle 10g Express Edition. We are 3 people working on a project and what I want is that once we update database in any of the Laptops, we can take its backup and hence copy the changes to other peoples laptops too. Is there a way to do this? 
  Thanks in Advance!</p>
