Hi everyone,
I was looking for some help about database design for online games and I have found Planeshift, an open source MMORPG.
Maybe I’m too young and everybody here know Planeshift but if you don’t and need docs about RPG or MMORPG just look into Planeshift’s source code. I’m not sure SQL is still the right choice with all the fuss around noSQL solutions that are more object oriented etc but still it is interesting to look at their work.
here is a video presenting their DB:
