Online Education- MongoDB and Oracle R Enterprise

I really liked the course developed by 10 gen for MongoDB (there are two tracks for Developers and DBAs at

The interface is very nice and is a step upwards from Coursera’s ( pioneering work (and even!/exercises/0 )– each video has a small question, the videos are not cluttered, and the voice and transcription quality is impeccable. Lastly a certification for people who clear 65% acts as an academic incentive, they get a certificate.

yes it is free.


Oracle recently launched a series of nicely made R tutorials at,P24_PREV_PAGE:6528,1but I wish Oracle R had some certifications too!

If only more techie companies like SAS Institute (expensive SAS training), IBM (cluttered website), Revolution Analytics (expensive partners in Certification), Google (unpolished Python lectures)

put an effort with polished e-learning interfaces than be dependent on external partners…..or internal gurus…interfaces matter especially in education.

\Well Anyways!!

Happy Mongo DBing/ Oracle R!
