ActivRecord APIs for DB transactions

Hi guys

Can i get some reference for studying all ActivRecord API related to DB transactions.

Hopefully this would help : http://api.rubyonrails.org/classes/ActiveRecord/Base.html

Another good link:

It is also good to know that the "save" and "destroy" methods already
use transactions to ensure before and after callbacks.
