[NTG-context] LuaTeX/ConTeXt connect to SQL Server

I apologize, I'm not completely understanding you.  So the reason I have:
 local presets = {
     server = "XXX\XXX",
     Database = "Customer",
     Integrated Security = "True",
     }
Is it would need to look something like this - or an equivalent.  There
Server would need to be the location of the DB Server, then the DB name,
and then some way to tell it to utilize windows authentication (this model
is based lightly on the C# connection model).

Is there not a prebuilt library to access SQL built into the LuaTeX/ConTeXT
libraries?  It seems that there should be a method in which I could include
a set of database queries in an external document that can link to the tex
document.  The closest I am to being familiar with any of this is Nlatexdb
(based off of latexdb and rlatexdb) http://www.ctan.org/pkg/nlatexdb .
I am rather new to ConTeXT and Lua so I am struggling with wrapping my head
around all of this as it is.
Perhaps if you could show me an example document that links to a DB might
be beneficial... I was hoping you would have shown this at the end of your
PDF.

Thanks!
