Architecture

Hello,

There is a particular web site that I'm researching that has their links set up in the following format:

http://www.website.com/index.cfm?event=academics.Curriculum

the "academics.Curriculum" part is what puzzles me.  Can someone shed some light on what type of architecture this company may be using?  I'm interested because I will be interviewing with them and want to understand how they set up their site.  I've seen another web site using similar notation.

Thank You!

Mike
