Hi, Thomas,
Though I've never done this and have never used Ingres, I don't see
why you can't create entities in an EOModel that reference the tables
and fetch them like any other Enterprise Objects (EOs).
An easy test would be to create the entities in EOModeler, than use
the data browser in EOModeler to see if it has access.
Perhaps an Ingres knowledgeable WO user can jump in here.
You mention that the system catalogs are readable, which, I presume,
means that they're not writable by just any database user. If that's
true you might mark the entities "Read Only" in the Advanced Entity
Inspector for safety.
Good luck,
Jerry

I am just beginning to work with WebObjects/EnterpriseObjects, and
as an Ingres DBA, am rather interested in accessing the system
catalogues (iitables, iirelations, etc.) via Enterprise Objects. I
was a little surprised that I was able to have EO connect and pick
up the user tables with no extra effort.
But can I somehow have EO recognise the system tables for reading.
(In Ingres, system catalogues are readable by any database user,
and are read using standard SQL statements.)
Ideas would be appreciated. Known solutions would be fantastic!
Cheers,
