Read Codd and & Date's rules. Can't remember which, but one of them
says "the database user is not permitted to know how the database
stores the data". In other words, empirical testing is FORBIDDEN.
Seeing as empirical testing is *the* "sine qua non" of science,
relational databases are, BY DEFINITION, totally unscientific.
So, if you want a benchmark, relational database theory explicitly
says "No way, Jose!" !!!
How does not being able to know how the data is stored prohibit
empirical testing? As long as you can provide inputs to a system and
retrieve outputs you can perform empirical tests.
