Noooooo...SQL ...!!

There are many SQL databases so far.But i personally feel the 15 years history of SQL coming to an end as everyone is moving to an era of BigData . As experts say SQL databases are not a best fit for Big Data No Sql databases came into picture as a best fit for this which provides more flexibility in storing data. I just want to compare few popular NoSql databases that are available at this point of time.Few well known NoSql databases are MongoDb Cassandra Hbase CouchDb Neo4j NoSql databases differ each other more than the way Sql databases differ from each other.I think its one's responsibility to choose the appropriate NoSql database for their application based on their use case.Lets do a quick comparison of these databases.

Retrievals are usually accomplished using SQL, a declarative query language. Relational database systems are generally efficient unless the data contains many relationships requiring joins of large tables. Recently there has been much interest in data stores that do not use SQL exclusively, the so called NoSQL movement. Examples are Google’s BigTable and Facebook’s Cassandra . Lets have a look at NoSQL  vs  MySQL (common relational database system).   When to go for  NOSQL ?? In recent years, software developers have been investigating storage alternatives to relational databases. NoSQL is a blanket term for some of those new systems. Cassandra,BigTable, CouchDB, Project Voldemort, and Dynamo are all...
