Help understanding db Transactions in Orchard

Topics: Customizing Orchard
Mar 8, 2013 at 5:21 PM
Can anyone please point me to a good tutorial / documentation / starting point to understand how to make transactions for custom Records with commit & rollback under Orchard 1.6 (with NHibernate & SQL Server). I have tried google-ing or implementing bits and pieces of code found scattered across the web but without any success.

Thanks in advance
