Leaving aside metasearch and broadcast search (terms invented more recently)
it is a shame if "federated" has really lost its distinction
from"distributed". Historically, a federated database is one that
integrates multiple (autonomous) databases so it is in effect a virtual
distributed database, though a single database. I don't think that's a
hard concept and I don't think it is a trivial distinction.
