Most of the time we tend to think in terms of an RDBMS way, and this is in no way a negative thing. However, it is important to try and switch your frame of mind when working with Ohm (and Redis) because it will greatly save you time, and possibly lead to a great design.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
