Re: [GUSDEV] Initial installation

[Steve F. <sfi...@pc...>]

Chris-

The application framework is used primarily to load data into GUS.  
There is a separate Web Development Kit that is used to rapidly develop 
a website that offers users queries against the data.

The application framework runs out of a directory called $GUS_HOME.  It 
just needs to be accessible to whomever will be using it.  It can run on 
any machine that has access to the database server.  We typically 
reserve entire machines for our db servers for performance reasons.   
The application framework, on the other hand, is very light weight to 
install.  You can either install a single $GUS_HOME in a shared file 
system, or, you can install separate copies in individual home directories.

i hope that helps a little,
steve
