If you're into the "Interactive entertainment industry" be sure to check out Rajesh Nair's new blog
Virtual Worlds, MMOGs, Serious data - Informix Technology for Persistent Worlds.
I am somewhat ignorant when it comes to virtual worlds and massive multi-player online gaming (unless you count Webkinz, where I play a mean game of Quizzy's Word Challenge), but it is clear there is vast potential for data management in this segment.
I am hoping Rajesh will teach me more about this area when I next bump into him at a conference. In the mean time his blog is a good start, especially the white paper it links to
Informix Dynamic Server - Fun and Games: The Data Server for Interactive Entertainment. Another link that caught my eye was a press release from February:
Icarus Studios switches from mySQL to Informix - that highlights some of the strengths and potential Informix has in this market.
