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.

It was an Awesome course. Really enjoyed doing all the exercises. Now I feel quite confident to write any queries.\n\nSpecial Thanks to Professor Jana Schaich Borg for teaching so wonderfully!!!!!

Sorry, I need to give this a course a 0 but since the review won't let me submit without scoring it, I'll give it a 1. It was designed beautifully and to maximize skill building. I really like the idea of using two different databases. However, the Teradata database was down way too long, much longer than it was up. People had to pay extra than planned to continue taking the course as a result. The instructors planned everything beautifully-except developing a backup plan in case the third party Teradata server went down, which it did. If the instructors or the university with they are affiliated have no control over this additional server, leaving the students helpless, they really should reconsider their use of materials outside of which they have direct control.

I recommend this course although the exercise requires more time than the average courses in Coursera. If you complete it seriously on your own you will learn a lot in order to apply it at work.

I thought it was good overall for teaching SQL and I enjoy Jana a lot... however
biggest issues were the time taking much longer than expected and the Junyper Notebooks not functioning, giving me even more time issues.
Also some typos in the quiz answer sheets and lack of clarity in questions (when clarity is extremely important for the answer!)

one star for the certificate;one for let me learn basic knowledge of SQL;the website often breaks down,so is the Teredata system ;the problem-solution system is also troublesome,hard to get the solution on time, maybe it is better to set a all-time online problem solver. No answer for teredata exercise also trap me for the hint in the teredata excersise sometimes not clear. Hope advancement for this course and the better experience of users.

The Jupyter notebook of the course had been not working for two days and I could not even see the course material in the notebook.

Poor performance of Jupyter and the wildly underestimated time commitments really sunk this one for me. The latter, especially is inexcusable. The syllabus is lopsided and, while organized, not enough thought has been given to the exercise workload.

The data sets are very hard to understand. The teacher should spend more time to explain the data set before assigning excesses and quiz with them. It took me two courses to understand what Dognition is doing (the video from the CEO is a very bad introduction, he did not explain the company very well).
When you ask questions in the course discussion forum, NO ONE answers your questions.

pretty useless seriously

Really bad course. Badly taught, strange choice of assignments and quiz questions. Unfortunately, I did the free trial and Coursera didn't process my cancellation so that I had to pay for a whole month for this.
Complete waste of time AND(!!!) money!

I think this course if poorly organized. The instructor is really trying to show us that the real life data sets and databases are messy, but providing only written instructions for me it proved useless. I, for one, need to see what other people are doing and not read long pages of horrible written explanations.
I paid for the course just to be able to do the exercises, which I also think it's a minus.
All in all it didn't "ENHANCE" my career prospects, mostly because nothing useful was taught here. Wouldn't recommend anyone to pay for it.

My experience with Teradata has been awful. Connection issues, latency, time outs. What should have taken 45 minutes took nearly two hours because of the load times for datasets. No clock or indication of progression for the queries.

I finished the course because I had to (I was exerted of paying fees) and then you agree on finishing the course. If I could I would have changed to another similar course some where else. Sorry but it is the true :)
I learned a lot not because how good is the teacher or how the course is taught but because reading a lot on internet.
I have taken many courses in coursera, so when I say this I have a reference to compare

Students need access to Teradata to complete the course, BUT the page providing login information is BROKEN. I have to quit in the middle of the course. That is a waste of our money and time!

The course content is good but its very poorly arranged. I am doing exercise and often find before continuing exercise 6, please watch 'that certain' video without providing any link. I tried to find the the link and finally gave up.
You must improve your contents in a better way.

I legitimately believe this is the best source for Data/Business Analysts who would like to learn how to use SQL for analyzing datasets. They take you through the step by step process of learning everything and also provide a lot of material (weekly quizzes and exercises) to review and truly test your understanding of what you've learnt. This course takes quite a lot of time which is great because it means that if you get through it you will have learnt a lot!
