ORDBMSs try to incorporate OO features into RDBMS. As a matter of principle
this is not possible without loosing advantages of the clear and straight
underlying relational algebra. So, in almost all cases those systems ending up
collecting disadvantages of the different worlds instead of the advantages.
There is no such clear and straight underlying theory for OODBMS. You can do
what you want as long as OO paradigms are supported ;) This is a fundamental
difference between OO and R. To reduce confusion we were thinking about calling
ozone an Object Server or something instead of a 'database'.
And no, ozone does not store anything in tables.
