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.

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.

The Teradata cannot be accessed

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.

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

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.

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!)

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.

pretty useless seriously

too long for the practise and just getting too long to finish one week

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!

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.

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.

Nunca pude hacer los ejercicios porque mi Jupiter Notebook estaba vaciá y nadie me pudo ayudar

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.

A very well designed course with no prior knowledge assumed. The discussion forums are very lively and queries (no pun intended) are responded to fairly quickly. A great option who wants to learn sql.

Happy to join this.

fantastic course

best practice!

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).

课程非常精彩！

Excelente curso

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

Solid course!
