My group here at Crane has been told that all our apps will have to be web enabled by 10/01/2003. Well we met to discuss several issues concerning this transition and I pointed out that if we are to do a complete rewrite of our apps to get them to the web, then lets get it right this time and ensure that all of our apps be 3 tier. Well by opening my big mouth I have been tasked to educate others on what is 3 tier and what are the benefits and the costs of converting our applications to a 3 tier path. So what I am asking for is some sources that I can send members of the group to that would explain/educate 3 tier to them (as most did not know what it was). Also could those with 3 tier experience respond to this post with the pros and cons of going the 3 tier route. I would like to know if it truly was the right path or did some find that 2 tier was the best they could do. Also management has not defined what would constitute the tools in any tier yet. So some ideas on what anyone is using to develop/maintain the tiers.

TIA
