How is a Teradata SQL query parsed and executed?

Hi guys,
I'm a student at Teradata. I found some diffeence when running SQL in TD and Oracle.
Can anyone help to explain the parsing and executing principle of TD SQL?
It'll be great if there is a comparision.
 
Thanks  alot!

It is very long.
I suggest you go through the link http://www.info.teradata.com/edownload.cfm?itemid=131540016 .
As for oracle, you can check with their website as I am a bit outdated with the versions. But it is an oracle engine.
which can be as good as these links:
