There is an unhealthy attachment to relational data stores today. It’s a tool, not an architecture or solution. We shouldn’t start with them and often should exclude them from our operational implementations. Reporting and analysis systems benefit tremendously from relational data stores. But we learned years ago that separate operational and reporting systems provided optimal performance.

I suggest those of you still unfamiliar with nosql operational data storage patterns trust companies like Trek10 and Accenture (where i saw great success).
