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 hard to navigate Teradata as it is has many bugs and issues. Quit the course mid way just to save time. It is so frustrating.

The technical support of this course is just terrible: just like many many other students (see the Discussion forums), I have experienced serious difficulties to access the databases platforms we need to learn and to complete our assignments. I can only echo the innumerable complains from my co-students about the lack of efficient support and technical reliability of this course; many of us are very unhappy about this, especially as they have paid for this course ... and what is Coursera doing about it, by the way?
My advice: beware before enrolling in this course and even in this entire specialization, and search for alternative options (there are many, not only on Coursera but also on EdX and others ...)!!!

The course content is great and I love how you get to use real, large data sets to practice queries. However, this course is ultimately costing much more than I anticipated due to technical issues, relating to issues accessing the Terradata exercises and juypter notebooks.
This makes it difficult to plan your week ahead of time, and I found myself rushing through exercises the moment I found issues were fixed to stay on pace with the course. If they had a better handle on the technical issues and better communicated those issues and progress fixing them with the students, I'd recommend this course.

This course is too much doggy! Please do not use Coursera for advertising your friends´companies, or at least learn how to do it a little more professionally to look really relevant! This psychiatric lady also seems to be sexits. Looking at differences between pictures with a girl and pictures with a boy is really abominable and shows an intentional discrimination and racism. It is really shameful.

1- The interface for My SQL (Jypetr) is not reliable, when I use a Query with no LIMIT the Interface get so bad.
2- The dataset used in this course is not clear to the learner.
3- the videos are too long comparing to the amount of information delivered.
4- There must be more shorts videos and should be more oriented the ideas.

As of June 2020, don't waste your time. This course is now useless since the third-party tool used by this course to open the Jupyter Notebooks is a dead link in the Duke University's server. There was an error processing this request: No jupyter instance available.

The course content is good, BUT the course administration very poor. They run out of license keys for the tool required to complete the course, so basically you have to keep paying the monthly fee without being able to complete the course.

Pathetic Course. So far the worst course of the entire specialization from Resource Support POV. The explanations given were far too complicated to understand as per me. Highly dissapointed. Also, Teradata was always a mess

It is very interesting, but we have to face problems with Teradata, I have not been able even to log in, and a lot of students are in the same situation, and the problem persists, even in the duedate of the test.

Quizzes are too advanced for a beginner course. Recommend to have simpler quizzes and the option for tougher questions in a more advanced course.
