I’m building some very simple site usage reporting into a project I’m working on. I’ve got a db table logging page hits with the following columns:
ID
Date
Time
StoreID
Referrer
URI
IP
UserAgent
Platform
What’s the best method to grab daily unique visitors based on this page hit data? I’ve done this before, but like I said my brain doesn’t want to process thought through all of the hurting. 
Thanks in advance.
