Case Studies

I almost never get to see case studies with this kind of technical depth. There are areas I'd like to see expanded upon: (challenges; successes; rationale)
In general, I'm just pleased to see this kind of information. I'd be interested in seeing a few more of these.

Very good case study, nice depth. I heard from a good source that they used Jini on this project too does anyone know anything about this?

We love this kind of content too, which is why we want to do as many of these as we can. If you are working on a project and your manager might be willing to publish some of it's interesting solutions, please contact us and I'll personally work with you to make it happen.

Check your geography,,,,

Floyd,
The article was interesting, but I found the graphic to be a bit odd. The stethscope is superimposed over the province of Nova Scotia, Canada getting a pulse from the town of Truro. I'm surprised that the Brazilians aren't protesting.

Hmm, well it was a weird shape but are you sure it was a Canadian province? :) Just to be on the safe side, I changed the logo to something more neutral, thanks for pointing that out. :) Brasilians have been upset at Canadians ever since we said they have Mad Cow disease so I wouldn't want to ruffle any feathers. ;)
packaged application suppliers

This is a very good article. In terms of getting more of these have you considered talking to some of the packaged application suppliers that build enterprise applications using Java/.NET or Ruby? For instance
Mercury (TestDirector is J2EE based - www.mercury.com/us/products/quality-center/test...)
Retial-J (www.retail-j.com/)
Metapack ((www.metapack.com/home/)
Reflexis (www.reflexisinc.com/REFLEXIS/)
Some Java conditions can be in the code itself...

From a purely object prespective, where every object is responsible for its well being some conditions like these
"<java:condition>clinic.getCode() != null</java:condition>"
should be a part of the object itself.
IMO, we need to differentiate between logic and rules ( as in contraints ). Otherwise, we would end up having the entire code writen in XML instead of the chosen language.

Does anyone know of more sources regarding the Brazilian Health Care System from a project management standpoint? I'm interested in learning about the team, schedule, and costs.
Thanks,

Does anyone know of some information regarding the running performance of this HealthCare system? Such as max concurrent user amount , response time, performance bottleneck, etc...
Thanks,
