Rules that apply:
2 - guaranteed access
3 - treatment of nulls (though different than an rdbms due to the inherent
sparse nature of rows)
4 - online catalog (not really true until Cassandra 1.2 and CQL 3
5 - comprehensive data sub language (only if you remove the word relational)
6 - view updating
7 - high level insert update delete (again, only if you remove the
relational requirement)
11 - distribution independence (very fundamental to Cassandra)

While Cassandra does nominally adhere to about seven of these rules, keep
in mind that rules are designed with a relational model at their core, so
many are totally impossible or just irrelevant to Cassandra.
