Hop into the wayback machine and fire up any flavor of PICK. The database where schema is applied on use, not on storage. No length limits on fields and very fast on old hardware (really fast on new). Storing bits of xml and code are no problem. And for those users who simply must have SQL, many versions will support that too (UniData and UniVerse are two examples). It's not cool, not new, but it does work.
