This is true. I would just like to point out that just because you build someting in a RDBMS it doesn't mean it's a relational database. More often than not this is the case. Many of the coorporate databases I see are set up on super RDBMS's with lots of tables, 50-100 columns per table, millions of records . . . and not one single relational tie between them. Makes me wonder sometimes. Received on Wed Sep 17 1997 - 00:00:00 CEST
