Benefits of NoSQL DBs

Some benefits compare to RDBMS (MySQL, Postgres, Oracle …) I come up
with after few months using MongoDB and Neo4J.* No model caching thanks to high performance
* No join thanks to embedded docs or graph DB
* Data-to-object matching is dead simple thanks to no-join and document-oriented
* No SQL injection attack
* No DB migration thanks to schemaless
* Scale horizontally
* Social computation made easy with graph DB
* No DB roll-up thanks to high volume and cap-collection

Q: How do I do data query & tabulation without SQL?
A: I do data query via MongoDB indexing & JSON query syntax and do
data tabulation via Map-Reduce.
