The Unofficial Diablo 3 Database was a site that we built as part of the portfolio for MMOS Inc. It was a custom PHP site developed on top of the Codeigniter platform – the backend database used MySQL with query caching.

The engine was built with two goals in mind:

1. To return results as fast as possible
2. To perform very well in the Search Engine Results Pages (SERPs)

The site became incredibly popular and several of the developers (myself included) were invited to Blizzcon as press to cover Diablo 3 related material. Since then, Zam Network LLC has purchased D3DB.com and added it to their network of game related sites.
