Hmm, a quick google search seems to indicate that the various SQL draft standards have been picked up by the dbperl package, and distributed to CPAN mirror sites as the directory refinfo inside the module "dbperl". The home directory seems to be one that may be close (in netspace) to Sweden: http://src.doc.ic.ac.uk/packages/dbperl/refinfo/ Hmm, there's an interesting Manifesto in there, authored by Darwen and Date (no copyright date on it, though): Seems they doesn't care for SQL very much as an implementation of the Relational Model. Ahh, web search engines are getting good (or is that bad?) enough to revive a favorite game of mine from childhood: "Things I learned on the way to looking up other things": A google search on a bare 'SQL3' turns up this link: http://www.objs.com/x3h7/fmindex.htm It's a couple years old, but has some white papers giving interpretations of the object models from different systems, including SQL3. The Manifesto I mentioned above also talks about OO (there, cheekly defined as an abreviation of Other Orthogonal, so the paper talks about RM Prescriptions and Proscriptions, and OO Prescriptions and Proscriptions) Specifically, how the Relational and Object Models might (not) interact. There's also a "state of the standards" page, though it's last modified date is 1997, and it talks about "upcoming votes" in '97. Still, an interesting take on the standards setting processes: http://www.jcc.com/SQLPages/jccs_sql.htm Ross -- Ross J.
