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.

Very well taught, could be better if videos are made where Jane works on SQL examples....walking the student through her solution.

THERE ARE SOME EXERCISES THAT NEED TO BE CORRECTED SINCE THEY HAVE MISTAKES. SOME TIMES IT CAN TAKE HALF A DAY TO LOAN JUPYTER.

WEEK 5 EXERCISES IN TERADA COULD HAVE BEEN LESS TIME CONSUMING IF FEEDBACKS WERE GIVEN FOR EVERY STEPS THAT YOU ACCOPLISHED.

Great course overall! Some areas of course are too wordy which makes it hard to understand what professor is asking for.

The Teradata part is quite challenging and I think it would be better if there are more hints. I like the SQL part more.

Great course, I recommand it without hesitation. However the questions and the answer keys could be a little clearer.

Good, comprehensive training on SQL. The later lessons take longer to complete than those at the beginning.

The course instruction is very good. If the Teradata database is improved, the course will deserve 5 star.

While the material and exercise is very helpful, you may experience some problems with the teradata login.

Derived attribute was never conveyed in the videos. So kindly add up the concept of derived attribute.

Could use further guided Teradata examples since the syntax does switch from MySql rather often.

Course was well conducted and explained, however, the final test was quite long and challenging.

Some practices are over-done. Doing the Teradata exercise without samples was torture.

It was so interactive and the practice exercise was much challenging and interesting.

Было бы здорово, если бы задания тоже были на русском языке, очень сложно переводить
