A "constantly evolving schema" is a limitation of an RDBMS to be fair. What seems to be missed by people who have problems with this is that a constantly evolving schema is a sign of design problems too. The schema is supposed to represent the *meaning* of your data - if the schema is evolving your analysis was incorrect at the start. How would you feel about a library with "constantly evolving categories" for filing its books? Anyway Charles, I agree with Josh's comments and just thought I'd point you at the following site that has plenty of discussion on relational vs object - oriented database systems. http://www.dbdebunk.com/ -- Richard Huxton ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
