Relational databases are general-purpose software, but that doesn't
mean that they are the right tool for everything. And storing large

I don't know what exactly they are, but I suspect that they are just
files (segments?) in Oracle's "file system" (tablespaces/datafiles).
So pretty much what we recommend.
