Here you seem to be using the DB as *only* a dumb filing system. It can also be the "logic" part of your sentence. Just because YOU use it only as a dumb filing system does not mean that is the only way to use it.

If you are in a domain that cannot take advantage of the features of RDBMS, such as in intensive unstructured graph traversal, then such may be the case. But, that is not a universal statement since many domains are not like that. (Or maybe you never figured out how to structure it better.)

And, anything is probably separatable with enough levels of indirection (interfaces on top of interfaces). But managing levels of indirection can be expensive in itself. Indirection is not free. It is always possible, but not always "good".
