The exercises and quizzes (particularly the teradata sets) were difficult enough that you have to think and structure your approach to arrive at the right solution. Very good learning curve.

I think this couse is a great choice to help you understand database. And you will get a lot, including how to use Mysql to manage your data efficiently as you finished all the lessons.

it was relatively time taking course for me but one who keeps on wins at the end.Thank You professor,duke university and coursera for providing such a wonderful course. Strongly Recommended

Each week's lessons are very well thought and I'd like to thank to the professors who created this amazing course. The last exam is very challenging! Be ready to spend +10 hours in a day :D

Excellent course for beginners looking to be able to utilize SQL directly or even understand how SQL works so requirements can be gathered with greater detail and why that detail is needed.

thank your for accepting my in the course i really liked studying it i suffered with some difficulties but i survive the course was very good but getting harder by week 4 but interesting

A​mazing! I appreciate the step-by-step approach taken to walk newbies like me through the thought process! In fact I used to doubt MOOCs being effective, but this course proved me wrong

MySQL lessons, quizzes and assignments are very well organised and taught. But was not very happy with the Teradata part. Overall it was a very good course! Jana is a fantastic teacher.

This course taught me a lot of information in a very organized and easy-to-follow way. The assessments were well-aligned with the content and practice exercises. I enjoyed this course!

Great course indeed. I read a few negative comments about extensive exercises, but that is the beauty of this Course. These exercises make sure that one has fully grasp over concepts.

it was an amazing experience with MySQL and Teradata. I have learned a lot of detail information on how to create a query, and I hopefully can use this knowledge in my future career.

Excellent introduction to SQL if students take the extra time to do the optional exercises and really get comfortable with the SQL syntax and nuances. Engaging and also challenging.

Very practical and challenging! However the Teradata content is much more overwhelming than the MySQL content due to its format (MySQL parts were explained thoroughly in Jupyter).

This is an excellent course indeed. Access to real world data is a huge +. Some of the questions in the quizzes were difficult though. And also the witty jokes by the Prof... :):)

It doesn't go into great depth but exposes you enough to SQL to give you a good start and an appreciation of how complex company databases are likely to be.

Works with real data.

It is a well-organized course. I really learnt a lot from the course. And the assignment and exercise work as a good practice for me to put what I learnt in the course into use.

This is a well-designed course with easy-to-follow instructions and great exercises.

I've tried other SQL courses on Coursera and this is definitely the best one for beginners.

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!

V​ery 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
