Only having to learn one language. No 'impedance mismatch'. Only having to define all your UDT, operators, functions once. Not having to manually keep the code written in the 'programming language' inline with the 'interface language' when the schema changes. Having relational capabilities in the 'programming language' - e.g. relational operations on local variables. Need I go on?
