This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.

A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

The exercises in the course helped give me practice for which I am giving this a 4 star.
Teaching SQL on video without real time practice was weird. Found myself going to websites like w3 schools so keep that in mind if you're considering this course.

Generally a helpful course. The biggest problem I think is providing enough examples. There are many examples in the slides but the results are not provided. I think showing both codes and the results will help people to grasp the concept more easily.

Nicely instructed by Sadie St. Lawrence.
Way the things are explained with examples helped me to understand the topics better.
I felt a little more explanation on Normalization and understanding the ER diagrams would have been could have been better

Sadie is a great teacher. This course is strong on theory. I would have liked to have had direct access to the data sets that I could use with other SQL tools but did not find this limiting in learning what was taught. A good foundation.

Very useful for me at my career moment. This is a good SQL course if you're a beginner to intermediate SQL user wanting to update or learn some SQL. But if your are already a advanced SQL user I feel the course might be too basic for you.

The videos are aweomse. I would have loved a little bit more material, e.g. a short summary of all the SQL entries discussed in the course. In addition, I think there was quite big jump of difficulty between week 4 and the peer assigment.

some quizes or coding tasks were worded pretty badly and were confusing to many students. It needs to be reviewed and edited. Also, more practice tasks between the videos would be a lot more helpful rather than giving 10 videos in a row.

The course structure is so very well laid out that on reaching the final week, I am hungry to learn more and more concepts and practical uses of SQL. I also feel that there should be more examples and coding assignments to practice.

I think i lreant quite a lot more from really googling. The course is an excellent framework, but you will need to reference a lot of external sources, for clarity, and for really understanding and aplpying the concepts you learn.

Good course to learn SQL queries. I think it will be helpful for someone who wants to pursue a career in data science. Final assignment and quizzes however were very confusing and not in line with what was taught in the videos.

A good introduction to SQL. The first few weeks were very informative and easy to follow, however week 3 and week 4 seemed disjointed. Some topics were covered very briefly, so I feel like my understanding Is not quite complete.

very nice course and good explanation
would have been nice if a summary document would have been provided at the end of each module to be able to look up content more easy and have a guide when writing applications later in time

I think the peer-reviewed assignment should be only on the last portion of the last project for the custom data analysis part only. Because the other questions are very technical and can accelerate the process of grading :)

I enjoyed the course and learnt quite a lot in a relatively short time. My only critic is that I felt there was a gap between the depth with which each topic was cover in the lectures and the complexity of the final exam.

It was a great experience to have a course. It was my first ever course as Online. I am thinking that the journey has started and it will never end. I also have selected the next course that I will complete in the next.

I believe this course focused entirely on retrieving data and no emphasis was given on creating or modifying tables. If these topics would have been included then it can come out as a complete package for learning SQL

This is a great course for beginners. One of the things which can be improved is to have more practice questions to use all the concepts introduced in the lectures. For example: I did not get a lot of chance to create

I have prior knowledge on SQL as a programmer. However after studying this course I got a another flavor of SQL from the Data Science point of view. I loved this course and the trainer as well. Thank you coursera.

Some examples in the later part of the course is a bit difficult to understand for those with limited programming background. Few broken down, step by step examples of complex queries will be highly appreciated.

The first two modules are okay and easy to understand, but the last two modules are little bit confusing, and from my perspective, the instructor is simply reading the script rather than teaching a lesson.

The course content itself was awesome! Be ready for some technical glitches though. As long as you pay close attention to the forum, you should be fine. Overall, I would definitely recommend this course.

I think the peer review exercise is a great way to test your learned skills. The lectures are easy to understand but I think it would be better if you added more info about the structure of ER diagrams.

As an introductory course is well designed and well explained. The supplement lectures were of great help. Maybe a little introduction to Analytical Functions should help to make it completely awesome!

Overall the content is good and the tutor is also good in the explanation the codes and concepts.
One suggestion there should be a more practical example and as well as how to run a query on a dataset.

Although several concepts are not explained very clearly and a number of assessment questions are unclearly worded, this course is otherwise an excellent introduction to understanding and applying SQL.
