For a database, the most sensible portable format would be CSV. That
way it can be imported, exported, edited, and manipulated with any
database or spreadsheet tool you users might have or want (even a text
editor). Unless you have complicated hierarchal relationships that
can't be easily expressed in tabular format, XML is overkill (and
relatively poorly supported overkill, at that).

I don't know of any Ada support for creating CSV's, but the format is
trivial to generate with standard Text_IO calls, and OpenToken
(http://www.telepath.com/~dennison/Ted/OpenToken/OpenToken.html ) has
support for parsing it.
