When NoSQL makes better sense than MySQL
TInniam V Ganesh:
However when there is a need to scale the application to be capable of handling millions of transactions the NoSQL model works better. There are several examples of such databases – the more reputed are Google’s BigTable, HBase, Amazon’s Dynamo, CouchDB & MongoDB.
BigTable is available only to Google’s employees, Amazon’s Dynamo only to Amazon employees, CouchDB is not scalable per se, MongoDB scaling architecture is young and complicated. How about this list: Cassandra, HBase, Hypertable, Riak, Project Voldemort, Amazon SimpleDB, Hibari(?), MongoDB?
