Either way, if you are interested in gaining the skills necessary to query big data with modern distributed SQL engines, this Specialization is for you.Most courses that teach SQL focus on traditional relational databases, but today, more and more of the data that's being generated is too big to be stored there, and it's growing too quickl

Good course to understand the need of SQL in data analysis/big data using good examples and real life data and problem sets.

Another informative course. I feel i learned a lot. I especially like the opportunity to do the honors sections to be more prepared for a Cloudera Certification if I decide to take the test. thank you!

Easy to understand and very well organized all the subjects.

It is a very nice and detailed course and it is completely appropriate for a new starter. The beauty about the course is that it teaches not only the syntax, but also all necessary hints and consideration points. All in all, time well-spent..
