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! :)

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

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!".

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.

If you've never had practical working experience with databases, this course gives so much valuable context to anyone pursuing a career working with big data. The material focuses on preparing you with relevant knowledge about database systems (past and present), that supports you in the next courses of the specialization which are more hands-on with coding in SQL-dialects. Initially I did not feel convinced I wanted or needed to understand much database theory covered in this course, and wanted to skip to the hands-on practice. However I've completely changed my mind after completing the course which has drastically improved my understanding of all current big data-base systems, their features, pros/cons, why there are so many variations, and helped me understand which database systems I want to focus learning on next. Unlike googling/studying myself online, I can actually be sure that the information given in this course is relevant and up to date. I highly recommend it, especially to anyone who hasn't had much working experience with databases yet- you'll gain a much better understanding of the current landscape of database technology.

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 is an introductory foundational course for SQL. You will not actually use the SQL commands. It gives good, clear, and interesting instructions on the concepts and structures of big data and SQL applications. I like the instructor, course format, and level. It makes sense to continue on to the next course in the series to practice SQL commands and the software applications.

Very good introduction to SQL applied to Big Data. The instruction is very clear and the lectures are very relevant. The quizzes and final assignment were mostly appropriate for checking knowledge against subject matter. The VM was also a very effective training aid.

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.

Excellent course! This course, together with the second in this series (which I have already completed) is arguably the best course to start with databases and SQL. Everything is explained from scratch and in a well-organised way so that it's effortless to follow and gain knowledge in a short period. The quizzes are well-drafted and logical, and the course does prepare you for that, unlike in many other courses!

The contents are rather basic, having to wait to the last week to see some applied concepts. There seems to be no technical support, so if you have IT issues with the project, you are on your own. The software solutions proposed for the project are outdated. The project is peer reviewed, which means that you won't get the certificate until other students have reviewed your project, and that may take a while.

Completed the first four weeks of the course with no issue. Found the content interesting and engaging. In week 5, learners are asked to download a program called VMware for future assignments/examples. Followed the link, took me to a website riddled with pop up ads that looked highly distrustful. Downloaded the required program and when I ran it, the program caused an instillation error and I couldn't get it off my device. The only way to remove the program from your device is through that program's launcher. In my attempt to remove the program with the launcher, it deleted OS programs and caused my full OS to corrupt. Spoke to an IT friend of mine who suggested doing a full scrub of the machine to factory new. Went through with him to do this, and 7 hours later it finalizes, screen full glitches out, and now the computer is full dead and will not so much as turn on even when plugged in. Main takeaway: it doesn't matter how good a course's material is when it destroys your entire computer. Would highly suggest staying away from the program.
