Thank you for your amazing course, very challenging quizzes and hands-on practice with writing queries. Definitely come back to this to review and recommend to my colleagues!

Very well-structured. The conceptual lessons are clear and helpful to understand all the logics behind. Using two sql platforms is also very practitical to gain the skills.

El curso esta muy bien desarrollado, realmente se aprende SQL. Los ejercicios para practicar son desafiantes y estan hechos de tal manera en que los conceptos quedan claros.

Took a bit longer than original expected! Good content, but you really have to find the time to focus on writing and refining queries when they don't work first time around.

phenomenal ipython notebook exercises! really well thought out and coherent with the tableau course. goes much deeper than other online SQL courses, problem sets can be hard

A lot of work, but totally worth it. I definitely feel like this course does a great job of teaching applied SQL, rather than just teaching you syntax. Highly recommended.

Great starter course for MySQL and how to use SQL techniques in multiple databases. This is a great course for understanding and applying data pulls for business purposes.

Excellent MOOC. Ideal to get hands on experience with MySQL and Teradata working on real data bases. Great exercices and great professor. The last week is tough but rewar

If you work with data this is an excellent course, but even if you are not a frequent data user you can learn a lot from the logic it explains. I absolutely recommend it.

comprehensive. no need to download or install SQL server offline, all the practices are online browser-based. but require lots of time to practice to complete each week.

Very strong course, the most serious course I took in Coursera! I don't use SQL in my work, but the base knowledge gained on the course has been useful to me many times.

Thanks a lot Duke University specially to Jana for encourage us to work ver hard in each lab of this course.

All information very useful and structured. Thanks again.

Fun, intuitive, full of information and practical works, I learnt so much through this course. Thank you so much, it was a pleasure to study SQL with Duke University.

This course is very good for beginners and then goes deeper into the matter. I would be very interested in an advanced course from Jana Schaich Borg, Duke University.

Great course with carefully structured material, and easy-to-absorb, bite-size information. As a student, I don't feel overwhelmed, but feel like I've learned a lot.

LOVE IT! Good for beginner, it will get a little bit complicated at Week 5 tho, but you understood all first 4 weeks' materials, you will eventually get there.

这门课非常有用，第二周的课程相对简单，但是后来三四五周的课程难度逐渐增加。特别到了第五周的考试，需要对前面所有的知识进行融会贯通，灵活运用，才能做出题目。这门课程也让我发现了做一名data analyst确实需要首先静心思考各个datatable的关系逻辑，对自己手里的数据非常熟悉才能更好的完成分析工作，感谢这门课。

That is a great course!

Plenty of learning material, challenging exercises and quizzes.

It was well worth the time spent, to learn SQL to a good working level.

Very useful and lots of resources and information, yet you need to search a lot in order to make sure you are qualified enough to start working on your own.

This course is a great introduction to SQL. The exercises and quizzes expose students to the SQL functions necessary for writing a wide variety of queries.

I came from a background with zero SQL background. This course had everything I needed in order to feel comfortable moving through the curriculum myself.

This course makes sure you learn MySQL in the most efficient way. I definitely recommend this course. Professor Jana is super awesome, I mean it. Thanks!

I love this course design, very thoughtful and instructive!! Especially having the real database to practise from, it is great for beginners like myself!

One of the mose useful and practical online courses I've ever had! Thank you Dr. Jana and all the orther people who put efforts in offering this course!

Course was well structured, I came into it not knowing anything about SQL but I now feel I have the knowledge to comfortably navigate through databases.
