Use of commit and rollback in oracle?
In Oracle, you can insert rows, update rows or delete rows from tables, but the changes are only current to your session. That means that if you insert a row in a table, no other users will be able to see it until you enter a COMMIT command. If you should enter or delete information by mistake, you have the chance to undo your changes by using the ROLLBACK command. The ROLLBACK will undo changes to data since the last COMMIT was executed.
