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.

The course structure was well formatted. The order of the lessons and content presented made for learning intuitive. The follow along practice queries and end of lesson practice problems were also helpful interactives for the student.
However there were mistakes in the answer keys or practice problem prompts that became more frequent in the lessons towards the end of the course. This made it difficult to practice the more complicated material and queries. It was also a big time waster when as a student you were unsure whether you were answering the correct question and if so whether your answer was correct. It would also been helpful to have more open ended practice problems at the end of the course in addition to the set provided.
Finally I think this course would be better split into two parts. The first part should be geared towards querying data and focusing more on just pulling data and intermediate queries. The main audience would be analyst/data professionals that have privileges to pull data but not modify data. The second part of the course would be more useful to DBAs or professionals that have database admin privileges to insert/delete/modify data. I would also focus more heavily on database schemas in this second course relative to the first.

I did not like going back and forth between MySQL and Teradata SQL. I understand the syntax is a bit different and you wanted us to learn that, but it would have made more sense to have a complete week in one, and then switch for the next week. There was not enough practice work in Teradata SQL in the later weeks of the course. Yes, the discussion forum is there, but you don't know if the suggestions are correct or not. It is very easy to go off in the wrong direction. This course could have provided more guidance for complex queries before the weekly exams. This was targeted to beginner users and would have more appropriate for intermediate with the complexity of queries in the last few weeks.

I definitely learned a lot from taking this course, but there were several frustrating road blocks along the way. These included items such as mistakes in the answer keys, a lack of explicit assignment instructions, and large jumps in difficulty levels between the later weeks. For those considering this course, be aware that the estimated time commitment provided by the course (8-10 hours a week) is a very *low* estimate. Or rather, that estimate is accurate for Weeks 1 & 2, but expect that amount to double by Week 5.
For readers' reference: I came into this course with a lot of experience with Microsoft Access but only limited experience working with SQL directly.

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 usage of 2 different platforms (MySQL for the exercises and Teradata for the quizzes) was very confusing given their distinct syntaxes.
Also, most of the explanations and practices were given on MySQL and then you are supposed to solve the quizzes in teradata, which has a different syntax, and also the exercise practices doesn't have any answers so is even harder to understand the errors when you are practicing.
The difficulty of the Quizz 5 I would say is not related to how much you practice and learn in the previous weeks.. is harder than I was expecting
