My view is that Cassandra is fundamentally different from SQL databases. There
may be artefact's which are superficially similar between the two systems, but
I guess I'm thinking of a move to Cassandra like my move from dBase to Delphi;
in other words there were concepts which modified how you write applications.

Now, you can do something similar to a SQL database, but I don't think you would
be leveraging the features of Cassandra. That said, I think there will be a new
generation of abstraction tools that will make modeling easier.

A perhaps more practical answer: there is no one to one mapping between SQL
and Cassandra.
