Hello! In a german spoken python ng is a thread running about DMBMS and Object-Databases. I was asked - becouse of http://www.postgresql.org/docs/8.1/interactive/preface.html#INTRO-WHATIS - how a "object-relational database management system (ORDBMS)" ist defined in the view of PosgreSQL, and what are the PostgeSQL features wihch make it a ORDBMS, not just a DBMS. Is there something other then inherance? I also found no realy good definition of ORDBMS, the only realy good I found was some pages in "Kemper / Eickler, Database Systems, german edition, 2004". Lg, AXEL.
