If you are an "absolute" novice with no knowledge about RDBMS and Big Data systems and all help from YouTube videos and other online resources have been of little to no help then you must take this course. It teaches you the very fundamentals of database design and builds your knowledge from ground up. It takes you from "What is DBMS" to a much higher level in a very short span. And Glynn is perhaps the best teacher you've ever met in your life! Give this course a try and you'll be happy and better off for having done so. Good luck and "THANK YOU GLYNN!".

The course is an excellent overview of database technologies and introduction into big data. Useful also for those who already worked with a few SQL engines. MIllion thanks to the creators! :)

Amazing course, full of useful information, the quiz are good way to test your knowledge and the instructor is an expert in this field and has very good presentation skills.

Big data is the one of the most emerging technologies in the world and this cloudera course will definitely help us to understand the hive and impala with practical.

This course was great, I have two years of experience with SQL since I am using SQL in my role of software developer. I've have taken this course in order to initiate myself to big data a field in which I am interested. This course was great experience, it has allowed me to really undestand SQL, RDMBS concepts, learn fundamental concepts of big data and be aware of big data tools used for analyzing huge datasets such Apache HIve and Apache Impala.

Awesome foundation to build on skills of query and analysis of big data and to use big data technologies like Hive and Impala

I Really enjoyed the course and the instructor is perfect

informative background info of Big Data that's good to know about. not too simple or too challenging.

I learned so much. I intended to continual review the entire material in this course. Thanks All.

Good course to understand the foundations of big data using good examples and real life problems.

Best course for learning the basic concept about big data and SQL.

Excellent class, earned a lot from the lecturer. Thank you.

Excellent fundamentals for data engineering

Great course, I'm amazed

great course

Muy bueno

It was a productive experience overall and a good introduction to the world of big data. A good way to understand the difference between some SLQ engines and how to organize huge amount of data. I'm looking forward to begin the second one.

This was a brilliantly taught course. Prof. Glynn Durham made it very easy to understand 'what SQL is all about' by his simple but effective teaching style. I loved this course a lot and about to start the next course in this specialisation. Thanks a ton for introducing this course.

I thought this gave me a very good understanding of the fundamentals of databases and how they interact, update, and store data. This will absolutely help me later on as I had no idea about any of this information.

Big Data a mystery? Solved. Intuitive and very approachable, the challenges of database design and logic for big data are explained. A good foundation to build on for Analysts and all others who may need to know.

If you don't have any background about SQL and you don't know where to start, I think this is the best course to start. It simplifies the concepts into easy ideas to be understandable.

Great foundational course for somebody who has some experience using SQL but no formal training -- it really fills in the gaps.

Amazing course! :) Very well introduction to Big Data ecosystem and gold-standard information about SQL.

Very well designed course for beginners and also a review for the intermediate and advanced.

Good videos and background info for database uses.
