Subject RE: reverse engineering a postgresql database: no relationships detected?
Date Mon, 01 May 2006 13:13:52 GMT
Not that this helps, but all proper OS X (Cocoa-based) applications
store their preferences in the defaults database, so yes, that is a
tried and proven idea.  It just seems like HSQLDB (or something) is
getting a bit confused from time-to-time.  I like the XML idea Andrus
mentioned, since it is human readable and editable.  And XML is very
enterprisey.  :-)

Not that I'm against trying new things, but do you know of any other
application storing it's preferences in a database? It seems like a
major overkill to me...but then, I don't know much about the specifics
of the modeler code so take my comments with a grain of salt.
