O/RMs Dissected: My first article for Software Developer's Journal

My first article for Software Developer’s Journal came out on the SDJ Extra issue. You can download it from http://en.sdjournal.org/new-sdj-extra-0212-4/. I talk about what an O/RM is and why it is useful. Here’s the introduction:

Object/Relational Mapping, or O/RM, is a hot topic. Talk is everywhere, it seems that new O/RM libraries pop up every month – everyone is writing their own, and Microsoft itself is putting a considerable amount of its weight behind its own solution. So, what exactly is an O/RM for, and why should you care?

Looking forward to hearing your comments!
