One of the best course till now I find on Coursera, well structured everything and practice questions made me feel like real life problems as data were from real database of dognition and ua_dillards.
Nice and well-organized course. I joined this course after self-studying on SQL for a few days. The context is really nice. The only problem is the Teradata is not stable. I tried very hard to login.

I learned a lot from the course. It teaches the core concepts of SQL and also provides practical applications and activities. However, even when I have already completed the course and got the certificate, I did not realize that it still keeps on renewing the enrollment for 6 months and took money from my card! I tried to find Coursera's "customer service", but seems that they don't have one. Tried messaging on Facebook and calling their phone number, but no responses on both. Their help page also did not help resolve my problem. I am still hoping that someone can help me with getting a refund. Thank you in advance.

The course starts out well, but by the 2nd half you pretty much end up teaching yourself by reading questions (that sometimes contain wrong information) and non-clickable article links from PDFs that work half the time. The Teradata interface is terrible, limiting you to seeing 10 lines of code in queries that are usually 2-3x that long, and without the line number references that most interfaces have that help you find errors. But it does cover the basics well before veering off into nested subquery logic that could have been done in easier ways.

This course provided a good introduction to SQL for me as a beginner and through challenging lessons forced me to learn SQL basics. After Week 3 however, I found that the level of difficulty increased steeply and not enough assistance was provided in the lessons to get through the course at a reasonable pace. In addition to providing answers to each week's exercises, further review of how the answer was obtained and the breakdown of the logic behind it would be helpful.

The initial stages of this course was wonderful and quite exciting. However, gradually it became hard and in my opinion the final QUIZ was extremely complicated and in contrast with the preceding quiz its a giant leap. I am disappointed with the final quiz and actually it made me lose interest in the topic matter.
Then again, considering the range of content, I am really surprised and the platform of delivery, specifically Jupyter Notebook is fantastic.

I brute forced my way through this class. Many new topics are shown in the exercises and not discussed. Some of the exercises have misleading (or incorrect) information which made me spin my head for a long long time. However... at the end of it I do understand SQL query formation pretty well. If I could go back in time, I'd force myself to take this class with a friend or partner instead of trying to go it alone.

The video instruction are not as helpful as I wished. They were too brief, and all the learning end up with doing the exercises. The regular exercises and the quizzes use different database system, and it sometimes hard to transfer what you learn to the quizzes.
The pre-quiz exercises are more helpful imo, but no answer key is provided. Sometimes I am still confused even after passing the quiz.

Great content, but this was over kill. The course was useful but I found it extremely straining to have to use 2 platforms (Jupyter and Teradata). I pretty much had to keep thinking everything twice, and it was over complicated especially that the Teradata website doesn't run smoothly and had many connection issues.

I was continuing with this course and have completed 2 weeks, but the Teradata Viewpoint doesn't seem to work. I am trying for the past 2 days and hence, I will not be able to continue this course. I liked the first 2 weeks though.
Good, difficult course.
Materials have errors from a long time ago and no one seems to be updating it. These errors are wasting students a lot of time. Mentors and staffs respond to posts in a polite and timely manner.
By TE Z•
the instructions of the final assignment seems a littble bit confusing. Many have reported the issues but the staffs didn't respond in time and the materials haven't been updated for a period.

Very interesting and hands on course. But not a lot of maintenance, explanations and assistance on the questions, especially the Teradata exercises.
By Tristan J•
The content is there but often poorly delivered, the videos aren't much help and it feels like the course is not setting you up for success.
By Jéssica A R•
Is a great course, However, I Think some materials could be explained more by the professor, and not just for the student read.
By Xu L•
A great course! However, some logistic mistakes prevent me from finishing the course. (Teradata account info)

I don't have any thing to learn about this course so it's very amazing for another person
By Yifan G•
there are so little video tutorials, and too many exercises without video instructions.

It will be better to combine the lecture and code.

Jupiter is way more helpful
