À propos du cours

In this course, you'll get an in-depth look at the SQL SELECT statement and its main clauses. The course focuses on big data SQL engines Apache Hive and Apache Impala, but most of the information is applicable to SQL with traditional RDBMs as well; the instructor explicitly addresses differences for MySQL and PostgreSQL. By the end of the course, you will be able to • explore and navigate databases and tables using different tools; • understand the basics of SELECT statements; • understand how and why to filter results; • explore grouping and aggregation to answer analytic questions; • work with sorting and limiting results; and • combine multiple tables in different ways. To use the hands-on environment for this course, you need to download and install a virtual machine and the software on which to run it. Before continuing, be sure that you have access to a computer that meets the following hardware and software requirements: • Windows, macOS, or Linux operating system (iPads and Android tablets will not work) • 64-bit operating system (32-bit operating systems will not work) • 8 GB RAM or more • 25GB free disk space or more • Intel VT-x or AMD-V virtualization support enabled (on Mac computers with Intel processors, this is always enabled; on Windows and Linux computers, you might need to enable it in the BIOS) • For Windows XP computers only: You must have an unzip utility such as 7-Zip or WinZip installed (Windows XP’s built-in unzip utility will not work)...

How amazing the course was! From the video lectures, the reading materials, to the practical exercises and the teachers as well, everything was fantastic in this course. Highly recommended!

Excellent course even if you have an sql knowledge with a bachelor. Especially the part where it explains the handling of NULLs which is not obvious and I didn't know about.

In depth look at SQL for Impala and Hive. Structured very well and excellent hands on learning with the VM and Hue. The middle section is tedious and you have to pay attention. It does all comes together at the end with real data analysis methods on big data sets. Good course but you have to be committed as a learner to receive the benefits.

This is a great course overall!

Having taken a couple of SQL courses over the years, they are often quite dry. Somehow, this one was much better. I liked the conceptual aspects covered with the syntax & applications. Rounded the education out quite well.

The only thing I would have liked to see more of is more practical assignments, like the one in Week 6. Even that was measured down in difficulty; perhaps the assignment can be made as part of the Honors section.

Also, definitely one of the better monitored forums in Coursera. With regular/periodic/helpful replies from Staff.

In contrast, I have generally found most Coursera courses to be quite poorly monitored comparatively. Its one of my bigger griefs with Coursera, compared to Edx - which generally has a vibrant discussion forum, thanks to the class members & staff/TAs

Thank you for bringing such a Awesome and High quality course - Cloudera . Course instructors are exceptional in presenting the course material in a clear, concise manner. I find this course to be outstanding because the Amount of practice that i've gone through with this course gave me clear insight On "when, where and how to use appropriate SQL clauses". but this course should have included more practice questions on joins.

It is an excellent course! Many thanks to the instructor of this course. All learning materials were presented explicitly and 100% clear. I feel so grateful because I finally understood how to write SQL queries and manipulate data (as I have never learned programming languages and subjects like these). Looking forward to the fourth course where the advanced sql techniques will be presented.

Excellent course! This course, together with the first in this series is arguably the best courses to start with big data 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 course of well designed for any beginner to learn how to operate on SQL dor finding out the insights from the data.

I would like to thank, the entire team of the Coursera and Cloudera for bringing this course in my life. It really helps me understand the concepts of database and SQL very well.

Special thanks to the instructor, Ian Cook.

Excellent ! Little bit exhaustive but worth it ! Total SQL refreshment course !

Clearly understood JOIN & its types ! Will never forget the Venn-Diagrams !

And the final assignment is a very good food-for-mind !

There was a mention of the 4th course in this specialization but not available; so is it not introduced yet ?

This was a fantastic course. This was my first time learning about the SQL language and analyzing big data, and the format of the course helped to ease my concerns about learning these concepts. I would highly recommend this course to anyone interested in big data analysis, expert or beginner.

Great content, which Ian presents in a hands on and engaging manner. I had absolutely no prior SQL experience before enrolling in this specialization, but after completing Course 1 with Glynn, I was able to pass Course 2. Thank you to Glynn, Ian, Cloudera, and COursera!

'Select' Query is simple yet very powerful, and the way it is demonstrated through this course is wonderful.

The instructor explained it very thoroughly, using simple language.

I can say, I can now use SQL to query big data at given time of the day.

par Wei P

Comprehensive, rigorous, and well-paced in learning the fundamentals of querying and analyzing big data with SQL. Covers many SELECT statements and clauses. Probably the most important course in the three-course series in terms of querying data.

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..

This course was very practical supported by several VM exercises in IMPALA and HIVE environments. The instructor accurately delivered the key points in SQL. I can broaden my understanding of SQL in general, IMPALA and HIVE in specific.

Brilliant course. I was tested at certain places which made me think about how to answer something for a day or two. A satisfying course to complete and I would like to take more such courses in future that tests my limits.

You might be a SQL guru or you are a beginner. This course gives a fresh perspective. If you "were" a SQL pro and need a refresher, go ahead finish this course. If you need an introduction to SQL, go ahead. Kudos to Ian!
