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 is very well organized and it's very useful to learn SQL. Be patient, take your time and to go through all the excercises to take advantage of its content.
However, the database platforms (in my case Teradata) was shut down for a couple of days, which can delay your accomplishment. I consider that the team of the course should warn when these issues are generalized.

Great opportunity to learn the fundamentals of SQL queries. Some of the material gets real complex without much explanation so it can be frustrating trying to track down the right answers and logic. This course definitely takes more time than what they allot so plan accordingly, but in the end I enjoyed learning the fundamentals of SQL from this course.

Really good Course if you have the time to follow all the workshops and assignments, because they take quite a lot of time to complete, so allocate some extra time so you can learn properly, the good thing is that at the end you will have a solid understanding of SQL, Query’s and how to mine data for answers. Highly recommended for SQL starters.

It's set out quite well and the videos and excercises are generally set out well and allow you to get good practice and learning.
However the difficulty really ramps up during week 4 and especially week 5 (you are warned of this). The spike in time commitment and difficulty is quite overwhelming if you are an actual beginner.

The course should be longer, prepare yourself you are going to need a lot of time, unless you have previous experience from SQL. It'll take maybe even more than one session. But it is worth it, because it covers all skills you need for working with SQL. If you really need to learn SQL, there is no better option.

Overall, it was a great course and I learned a lot from it. I think that what could have been better is if the content of the course was more spaces out right than tight because I think for Weeks 4 and 5, I needed to learn more about how to write advanced queries.

It's very practical but hard at the same time. I like the teaching style. What's makes me little uncomfortable is that the teradata system guidance is kind of obscure. However, the Jupiter guidance is really yummy. Hope to learn more sql applications in the future.

The course is very thorough but i woul have loved it if you had a way for instructors to better reach out to classmates rather than leave things to chance and everyone is confused for month. But either way the experience is priceless. Would recommend it to anyone

Excellent course structure designed for students with no technical background to understand how industry analytics works.Real company databases donated by dognition and dillard's helped a lot to understand real analysis problems.A good experience overall.

Great course, I enjoyed it a lot and learned more than I was expecting to. There was a lot of problems towards the end with Teradata, the website was down for a couple of days. A bit more of technical support from the administrator would have been nice.

I won't give 5 stars only because Jupyter from time to time has crashed. Apart from that, I think the course is well done and also the exercises are very helpful.
Thank you for giving me the opportunity to learn MySQL, now it's on me to get better.

It was a great experience learning with all this good content with the best teacher. Just need to improve your service and query problem. I have faced issues while doing the practice of Teradata I complain about it many times but no response.

I prefer have the result of the question. I prefer check the result of my query in order to be sure that I done well. I have lost time to revise my query when they are good and other times I believe my queries are good meanwhile I was wrong.

Questions for exercises are written in an overly complex way. I often got stuck because I didn't understand what the lecturer wants from me. And my English is C1.
The rest is good. Nice practical datasets, clear explanation of the subject.

Excellent course, really helped me learn the fundamentals of SQL. I thought in some cases the questions could have been worded a bit better, but overall I thought the professor provided an excellent basis for me to learn the material. I

Overall the course was very helpful, the exercises informative, the approach to encourage learners to explore stuff rather than being spoon-fed queries. Thank you, Jana for this wonderful experience, and thank you, Duke University!

There are great practices but I don't appreciate the fact that once we are done with the exercises, we are locked out of it. I would definitely have preferred to go back and revisit and refresh every now and then.

Excellent course. the assignments are really challenging and require actual practice at real world problem solving. there are some mistakes in the course materials that took me some precious time to figure out.

The actual amount of time required per week to complete the course was well over the 3-5 hours/week advertised on the course homepage. It was a very time intensive activity each week- especially the last 2 weeks.

The course is great. There are a few problems with Terradata. I think if they offer an extract of the data in spreadsheet form, the problems would be much easier to work with. Overall, the course is good.

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.

Very good, detailed course, I can recommend! Before that I knew nothing about SQL, now I have moved to higher level of analyst. Sometimes the instructions are not 100% clear, but it is minor problem.

The notes are perfect! But I do think that the content might be a little bit easy.. Good course for beginners, but if you are looking for more challenges, this might not be the best choice for you.

Its a very good class to learn to use SQL in a systematic manner, even if you had used SQL or are completely new. The two Databases ( Terradata and Dognition) gave a lot of valuable practice.
