General question on handling very large datasets in Mathematica

Greetings,

I am about to begin some research work with a very large dataset -- 
several million records (though each record is relatively simple). I 
plan to use Mathematica to estimate a number of statistical models using 
various subsets of this data. I was wondering if other MathGroup have 
any experiences they could share using Mathematica to handle large datasets. My 
particular concern is Import-Export and general reading of large data 
sets in Mathematica. I can have this data in a variety of formats, from pure 
ASCII to any number of RDBS formats.


I apologize for the vagueness of this posting.

Regards,

Mark
