RDB grew up before objects did and as I mentioned, had enough of a head start that they were able to solve these questions earlier on. OODBMS grew up in a crowed space using a technology that was not well known or well understood at that time. Today given equal opportunities, things might be different. That said, we can't roll back the clock. However, RDB technology is facing some technical hurdles that will force it to either adapt or wither.

In my years of working with OODBMS I've never seen this. OODBMS technology as it has been implemented faces the same technical challenges as RDB + a couple more. Getting good performance out of a database was always easier with RDB. The biggest advantage was in early on speed of development. OODBMS got you up and running with about 40% less effort.
