Re: for a school project
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. -Tupshin On Nov 27, 2012 7:02 AM, wrote: > Hello, > > I have a question about codd's rules and cassandra cuz im doing a school > project sith my colleagues.
