Dear Roottalk,

Congratulations on the phenominal software.

My application involves business data. The data is on a single 
server/terminals configuration at many locations. The data is sales of 
various products over periods of time or pricing range and varies at each 
location.

I would be using only a small fraction of the data analysis available in 
Root to create histograms in 2- and 3-D, function evaluation and graphics 
and visualization, possible curve fitting. I would want to get first and 
second derivatives of the functions for display and evaluation on the 
terminals. Root macros or executables would presumably be used at each 
location.

Root is big but its' tools and characteristics of C++ based, open-source and 
display sound ideal for our application. Are there examples of Root being 
used for these kinds of applications? Would Root be a good fit here even 
though we'd be using only a small part of it? I see you have tutorials and a 
User's Guide. Where do you suggest I start in putting this together?

Please help me simplify or gain an overview of some basic ways I might 
proceed in doing some of the things I've described and begin to learn some 
of Root's tools. Thank you.

Sincerely,

Joel Gerstman
