GSSaru,
Dare I suggest you consult the documentation? Both the Parallel Job Developer Guide and the Online Help Files contain good descriptions of the differences between the three stages.
If you're really stuck start with the Parallel Job Developer's Guide section "Join versus Lookup".
HTH,
J.

Section 3-3, middle of the page of the DataStage Enterprise Edition Parallel Job Developer's Guide. Read it for yourself.
