Usually the 3rd party software you are using will employ a highly specialized data structure (either in memory or on disk) dedicated to the analysis it is doing, and so that software will dictate how the data is stored. If you are lucky it will fetch the data itself from the database, given either a statement handle or a SQL string (or a set of accessor methods, although I'm not sure how lucky that would be). If you are unlucky you may need to create a "flat" file to serve as the go-between.

If you want to contact me via email with more details I may (or may not) be able to give better advice.
