The other day I decided to start doing some analytics style queries purely in Linq against my existing normalized structure. Normally these types of queries are best suited on a Star Schema, but I think for what I wanted it was simple enough to do in the transactional tables, plus most sites don’t have a true “data warehouse” anyways.

First lets go over what I was looking to do.

For a given date range, get the total number of logins per day. Use only Linq in my EF model ( no stored procedures). Most processing should happen in the DB I know what you are thinking, that is super simple. I agree it is, but there are some hidden complexities that I think are worth sharing.
