NoSql vs Relational database

Hello Gurus

I am a SQL-Server developer + Development DBA (Production DBA is managed by our hosting partner)

While i was surfing the web, I came across NoSQL article (Link below). Is this something relational database guys has to be concerned about? I am concerned on what future holds for SQL-Developers and SQL-server DBAs

Any thoughts gurus?

Concerned? No, unless you intend to know SQL for a particular vendor and learn nothing else for the rest of your life.

"NoSQL" isn't intended as a pejorative against SQL or relational databases. It's short for "Not Only SQL." It says that not all persistent data problems are relational.

Analysis of terabyte or petabyte sized data sets might not belong in a single relational instance. New tools will be needed.

Change is good.
