I'm not so sure. It seems that the shoehorning that is done to get data into the tables cause some problems. Possibly. But I shudder to think of what it would be like if there was no powerful standard tool like SQL for essential add-hoc queries and fixes. That is what you'd get with custom file storage. Also the "shoehorning", if done right (normal forms and all that) prevents duplicating information, and all attendant problems.
