    +1 for rounding out some of the points not called out elsewhere. I hadn't even considered the security angle. One minor nit-pick: in a couple of places, you referred to database, where you really meant DBMS. One of the factors contributing to the mess the industry is in, wrt knowledge management, is a terrible lack of precision in the use and interpretation of terms (e.g., conflating "table" and "relation", or worse, conflating "relation" and "foreign key").

    +1 I especially agree with "database independence is generally a waste of time". It's a nice ideal, but never works in practice. The security angle is an interesting one, but I think any application that needs to do CRUD can't protect the DB from itself - and that would be the vast majority of applications.

  • @Marcelo: updated with better precision on terminology. You're right. Commented Jan 11, 2011 at 14:52

    Security: I wouldn't advocate the use of ORM anywhere where SQL security was used. Commented Jun 28, 2011 at 9:27

    Agree with points 2 & 4 though. Overall I would say that one could say similar things about many coding tools - Generics, jQuery, multithreading, SOA via WCF etc etc. All very useful tools/techniques in the right hands. However, I have seen them all abused producing difficult to maintain/unecessarily complex code through a lack of understanding in how to use them. ORM's don't make you a good coder - you probably need to be a better coder (or have one on site) to use them - it definitely raises the intelligence requirement on new hires, but on the right project, it's a boon.
