You also might want to take a look at my other post that goes into a
bit more detail on the motivation for the use of B-trees, by
comparing them to lists and balanced trees (such as red-black trees).

So then, is the argument that relational databases store empty

This is actually not true. flat tables are the abstraction presented
to the user (or programmer) with relational databases, but the
underlying storage model is, more likely than not, based on B-trees,
just as it is in MUMPS. This can be confusing, because the basic
abstraction presented to the user in MUMPS is multi-branching trees,
but that abstraction is not the same as the underlying storage model.
