Anyone who wants to is welcome to download and use the Access database that I created for analyzing website usage logs. It's the same database I use to generate some useful reports that I couldn't get from Webalizer. It's available at:
http://25yearsofprogramming.com/msaccess/webstats.htm.
It is GNU GPL open source. You can even make improvements to it and publish your improved version on your own site, if you wish.
I'm open to ideas for other queries or reports it should have, as long as they don't duplicate reports that you can get easily from Analog or Webalizer.
