“The way Teiid is supposed to work is it focuses on
data virtualization allowing real data access without having to
move data (yes I know on *nix systems we’ve long had symbolic links
which is a similar concept at a lower level).“The way Teiid achieves its data virtualization is by way of
Java Database Connectivity (JDBC) and Web Services interfaces. The
new open source project is part of Red Hat’s JBoss division and
comes out of technology acquired by Red Hat from its acquisition of
MetaMatrix in 2007.”
