Not knowing MS SQL inside out was becoming an issue w.r.t. my career. I knew I had to ramp up on some data storage technology. NoSQL seemed to be the perfect choice :) Also at SDD 2014 I attended a lot of sessions on MongoDB, and I finally got started.
To make my knowledge on MongoDB more formal, I decided to take up MongoDB university's online courses:
M101P: MongoDB for Developers
M102: MongoDB for DBAs
M202: MongoDB Advanced Deployment and Operations
M102: MongoDB for DBAs
M202: MongoDB Advanced Deployment and Operations
These are free courses, but they also offer paid certification, I will be attempting the following certification after completing M101P
