Welcome to CodeRanch!
Firstly, please check
HowToAskQuestionsOnJavaRanch. I'm not getting what your exact question is. Is it about Cassandra being better than relational database? Or other way round? Or is it about why asymptotic notation is used for database?
Also, please
CarefullyChooseOneForum. I really doubt whether Cassandra has anything to do with
EJB certification.
