It's not so much that it can't be done in a flat-file DB, but that the flat-file implementations take longer to implement, more effort to maintain, require more computing horsepower and run slower.
You want another datatpoint? Look at Tekelec in SoCal. Their Oracle migration, done by "the experts" is massively over budget and is maybe, if they're lucky, up to 80% of the functionality of the original implementation.
