Keeping statistics....

[eluser]codelearn[/eluser]
I have a fun/interesting problem for anyone willing to tackle it. I'm not looking for code or anything, just an idea of a spec for this functionality.

My website has a bunch of restaurants/business' which list their info. We also have created a backend for these places so that they can edit all of the info. Now, they are asking me to create some sort of bar graph of how many people access their specific listing each month.

The exact problem is how to collect the hits (CRON job, on page load?), how to store them (a field for each month? but then what about next year? we would like an archive) and then finally how to display them in a graph (least important).

This task isn't horribly daunting, but If anyone has done something similar I would greatly appreciate your input that would save me a great deal of time.

Thanks all.
