Even if you work with an ORM instead of writing raw SQL you should know when single row processing is OK and when bulk load / data set processing is a must.

My last employer lost 5M+ euros (not reveue but profit) every month because of excessive use of PL/SQL single row processing.

How could they lose that much $ due to single row processing? Having to buy that much more processing power?
