One other intriguing benefit of NoSQL that I started to unwitting benefit from recently is the ability to push data scheme concerns entirely to the application layer. In this scenario, the applications use a NoSQL database predominantly as a storage service, lightly structured by a few indexed key fields. The object structured data document within the payload becomes transparent to the database. The applications then assume the role of enforcing and understanding the data scheme.

This approach allows the application architect to encode the data structures and meaning directly in the code that creates and consumes the data. So data structure changes required for functional updates can be implemented, tested, and deployed in the application code base with no updates to the database layer at all. (Of course, a conversion of existing NoSQL data documents may be required in situations.)

In this NoSQL approach, the removed translation of object data scheme to a relational structure and, and then back to an object structure again is a very welcome relief as well. --use-the-index-luke.com

Moving in Circles: SQL for NoSQL



We've been there, done that.  

In Coming Full Circle: Why SQL now powers the NoSQL Craze Ryan Betts, CTO at VoltDB, argues that NoSQL products should adopt SQL for queries. I don't know about you, but to me it looks like a contradiction. Let me make it clear that my intention here is neither to defend SQL, nor to criticize it--I sure have done enough of that during the years--but rather strictly debunk the notion that its use with NoSQL systems is a good idea.

After attending NoSQL conference I am really hoping that companies think through this 'big data' implementation! No one there was interested in Data model ... and said so ... forget the data model ... even 'standards' were looked at 'its 'too early' for this new technology ... and no one could tell us anything about 'meta-data'...!!!!! --LinkedIn.com
