You are almost certainly referring to the IDL database format designed
by Don Lindler more than 20 years ago, mainly for astronomy. This is
a simple, flat database format but I still find it useful for small
( < 3 million entries) databases, when one does not need to often add
new columns or perform exotic searches. The main advantage is that
the database entries map easily into IDL vectors and arrays, so it is
easy to plot or process the data. The procedures and a README file
located at http://idlastro.gsfc.nasa.gov/ftp/pro/database/ and a
LaTEX file database.tex located at
http://idlastro.gsfc.nasa.gov/ftp/text. The LaTex file gives a
description of how to create the .dbd file, which is an ASCII file
made with an ordinary editor, which describes the data type and other
information about the database columns. It would probably be
useful to examine one of the .dbd files for some of the astronomy
databases stored at http://idlastro.gsfc.nasa.gov/ftp/zdbase.

For a completely different approach, you might look at Marc Buie's IDL
interface to a MYSQL database at
