Learner Reviews & Feedback for Managing Big Data with MySQL by Duke University

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!

The course is well structured and it really brings you from inertia to coding in SQL (even if not in a high level). I'm more aware now of the relationships by using subqueries and joins, and this is certainly an up.

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.

Excelente curso, disponible en múltiples idiomas. El acceso a las plataformas para poder practicar es excelente. Los ejercicios van subiendo en dificultad, permite el aprendizaje progresivo.

It's hard to understand the data that given for quizzes but the teaching of professor Jana is really amazing.when i ask questions in discussion forums there was no tutor to help you out soon.

course was very interesting and was very thoroughly done , examples given were very good and helpful and I am very sure it will help in the long run!!

thank you.

it was a wonderful journey.

It's a great course for beginners, maybe being deep into two databases isn't fruitful enough. Web pages like kaggle.com can give more examples, more interesting and with current data

Great SQL course. I think the course overall is well structured and let me stretch myself week over week. It's a little difficult to write long query in SQL scratchpad though.

Very helpful and good course. The main focus is on the practice. There are many exercises which help to practice which in turn helps to understand the concept more.
