Hi Shaun

Have a look at this:
http://www.foss4g2006.org/contributionDisplay.py?contribId=69&sessionId=52&confId=1

This is one solution that makes use of a three tier architecture
1. Mapbuilder (Client)
2. GeoServer/Mapserver (Application Server)
3. PostGIS (Spatial/Non-spatial data)

This does date back to early 2006 and I'm sure someone can suggest a
more up-to-date technical solution.

HTH.
Cheers
Shoaib
