學生對 杜克大学 提供的 使用 MySQL 管理大数据 的評價和反饋

This course provides an enormous amount of practice for SQL queries that other online courses lack. As in some of other online courses, we see instructor writing most of the codes, and there is not a right amount of practice for students.

Great course about database.

This course come from basic background in Relational database rather then go detail to syntax SQL.

Beside that, it provide real big dataset (around 100 million records, woa)

Thanks for creating such great course

A good challenge for those who want to feel confident querying databases. It forces you to work through the processes and as a result the learnings are much more substantial. I am very glad I took and see immediate benefits in my job.

Thanks to my teachers Daniel & Jana. Learnt how to apply mySQL & TeraData into my real business world. Great insights offered to deep dive with the given data and what needs to be applied to make it logical. Thankyou once again!!!

Awesome course - I learned a TON of SQL. Feel very confident, and expect that I could rely on SQL documentation to develop more advanced queries. It took a lot of time, but if you give your time to this course you will learn SQL.

This course really touched on all the most important aspects of learning how to use a SQL database while also providing many supporting materials for reference. I was very satisfied with the quality of the materials and teaching.

Great Course, i learn a lot with Jana and i like so much how she explain everything, i am very sure that the onl way to improve knowledge is practicing and this course is intended to teach trough finish every exercise. Congrats

If you choose to follow this course, you will have to invest a lot of time. There are few videos, but you will go through a lot of exercises that will make you learn (or recall, like in my case) SQL in a very effective way.

Best course I've ever taken on coursera because it's all about practice instead of theory - and the quizzes/practice questions are extremely difficult but once you get through it you will definitely say SQL is a skill you own.

It is definitely a challenging course, but one that can really make you learn and feel confident in the real world. It was huge that we got to work with real and messy datasets, this for sure enhance the learning experience.

This course was really awesome!!😊

I am happy to learn those skills which was essential.I enjoyed studying with Ms. Jana Schaich Borg that she did her hard work to teach me.I appreciate her skills and hard work .

Thank you ^_^

By providing those messy database which is the case in reality this class really improves our way of thinking when it comes to writing SQL commands. Also those operators and functions are really useful taught in this class.

Fantastic course on SQL for those with no prior exposure. Also addresses basic database structures, relational schemas, and ER diagrams, providing an excellent foundation for further work with data in relational databases.

A useful and necessary course for confident use of queries in databases. The concept of the main query framework allows you to adapt and use different query languages. Thank you for the course now I know more than before!

The course provided was clear and help me learn about SQL a lot. The only thing that bothered me was the problem with Teradata that wasted me and other learners more than 2 weeks of course time. Keep it up and thankyou!

The course is challenging as it pushed you to deal with real life data set so you not only leaned the language but also how to structure your analysis plan and to execute it. Well designed on-line tools really helped.

I would like thanks Jana and all of her colleagues who helped in providing this course. Since this course has much importance from job perspective. I would also like to thanks Coursera for providing me an opportunity.

This was one of the best courses I've ever taken. Each lesson built on its predecessor logically. I worked hard to learn each of the concepts, but was very impressed by how much I had learned by the end of the course.

Thank you Dr. Borg. Really teaches you SQL from the very basics to an advanced level. Lots of practice. Lots of making you think. This course is significantly longer and more difficult than other courses on Coursera.

Out of the four courses in this specialization, I feel like I have learned something completely new. It challenged me to think in new ways. And in the end, I am walking away from this course with a marketable skill.

Learn MySQL and Teradata in one course. Lots of hands on work and help for assignments. The only way I actually learn something. Just do it. I have a SQL server background and had to experience life without CTEs.

Thank you for this comprehensive course in using SQL in buisuness analytics. I`m studying JS programming but I think course helped me to learn basics of MySQL relational databases. Practical lessons were fruitful.

I have to say that this SQL course is perfect. Although this is the second time I learn about SQL, it still gives me some knowledge and the quizzes

are perfect despite there are some minor errors! Thanks Dr. Borg!

Excellent Course. This is the course I am going to recommend to everyone. This course has tremendous opportunity to practice and practice and thus makes everyone capable of writing from simple to complex codes.

Great Course, as it covers everything from basic's to advance level database management.

All the important points were explained in very simple terms.

I will definitely recommend this course to all my colleagues.
