AdaptableStorage (Ape, now, right?) maybe: it can do anything. 
DirectoryStorage is a file-system based storage, with nothing and 
nothing else to do with relational databases. Unless you consider the 
filesystem to be an RDB, in which case you're wrong. (The filesystem is 
a database, and usually a pretty good one, but it is not relational.)

There are various specialized RDB-based storages: BerkleyDB, Oracle, 
maybe others. These map the ZODB into a relational database. I don't 
know that I'd prefer these over FileStorage or DirectoryStorage.
