Differnce among the various DB?

Question

what is the difference between mongodb, cassandra and also other DB?

Answer 1

Right now, it seems like both MongoDB and Cassandra would be likely options. My situation:

Lots of reads in every query, less regular writes

Not worried about "massive" scalability

More concerned about simple setup, maintenance and code

Minimize hardware/server cost
