It could be, especially if you are about to write a bunch of
functions to access those structures. But equally if the
structures accurately reflect the problem and acess does
not require any complex processing then I'm happy to use
the structures.

In a case like this I'd still tend to move to a database rather
than an OOP solution, although I might use classes to hold
the returned data.

I'm still not clear why the OP wants to hold the data in
memory.
