Not if you program in SQL from within the RDBMS.

Well, that may certainly be true, but does not relate to the applicability, or in this instance, the ineffectiveness of the current RM to address this (object) data.

Either way, application servers are (usually) a step backwards. My focus is building suites of application system components as SQL stored procedures within the (R)DBMS to the extent that there exists zero components external to the (R)DBMS.

The modern (R)DBMS environment is capable of "internalising" the entire applications environment.
