If the final assignment was not so ambiguous (many questions are misworded leading to wrong SQL codes, it is almost impossible to decipher what is being asked exactly) this course would have got 5 stars from me. Otherwise I liked the pace of the material other than maybe Week 1 and I enjoyed the coding quizzes.

Good course, learnt the basics of sql and some of it´s features. However, i think more excersises should be made, as it make you feel you didn´t train enough. Maybe one good option would be letting people hae acces to some databases, and then use a SQL program installed in the computer and work from there.

The course was great up until the final assignment which was very ambiguous. It was also a shame that they used such an old version of SQLite, where many functions are not available. However, I feel that it did fulfill the goal, which is to make their students be perfectly prepared for SQL in Data Science.

It is not one of those too much detailed courses and for some stuff you will need to look them up in a different source. And it lacks coding and testing in the lessons. Maybe with lab sessions it would be better. On the good side exercises are great and they make you learn the most things in this course.

This course provided essential knowledge for using SQL in data analysis. The best part was the quizzes at the end of each module which enabled a complete practice of the concepts learned and the last exercise was very helpful to understand how SQL is deployed in solving real life data analysis problems.

It was a very good course. A person with no prior knowledge of SQL can easily learn this course. I would like to suggest that for certain sections like joins, date-time, the course provider may consider introducing some animation into the lecture videos to illustrate how data is being linked/extracted.

The course is good but lacks proper explanation of queris and required some more illustrative way to show the handling of queries in videos.Requires proper graphics and additional programming interface to sshow and run the various queries discussed by the tutor in the videos for better understanding.

Expect peer review section this course was good. That peer review section confuses a person that how to do the task and what needs to submit. So in the place of this peer review include completed a problem data along with instruction and some hints and grade that as other assignments of this course.

The contents are very accessible and well done, as well the support tool for exercise is great!

However, you should consider to improve the final assignment questions. They are not clear and the database needs a code book with the metadata. It was tough to get the meaning of each field and tables.

As introduction to SQL , I have found it very useful and well structered in order to get a better a grasp on the topic. The only thing I will improve is the part concerning self joins which by the examples shown in the videos I didn't get all. Maybe add more examples.

To sum up, very good course.

Most of the lectures are clear, but in some of them there were no examples of the output of the code, so it was hard to understand what the query returned. Otherwise, the practices were somewhat challenging, but not too difficult, the course was interesting and all the objectives were addressed.

Great place to start if you have absolutely no SQL experience. Videos are well paced and thorough. The final project could use some cleanup--as indicated by the forums full of people asking the same questions. I'd take another in the series if it started around the level of windowing functions.

The course is very useful for the sql beginners. Struggling with the quiz and especially with the final assignment, one can learn a lot. However, it would be great to have more hands-on practice during the lessons. Despite this, I enjoyed the course very much and learned a lot. Many thanks!

Course provides great information but the structure could be improved. I advise that you open the practice quiz and consider the questions asked while watching the endless stream of back-to-back video lectures. You should attempt the real quiz and coding assignments on your own. Good luck!

The material was simplified. I would have liked to have learned more advanced techniques in SQL. Most of the material is refresher for me. I've been doing SQL for over 10 years now. I was a little rusty because it's not my day to day anymore. I would love to see a formal course on no-sql.

How can i say about this course. Overall, course isn't bad, neutral. Tutor's pronunciation and English is so good and accurate and she always try to explain the course in detail. Disadvantage of this course, it is so theoretical and doesn't have many practical explaining during the lesson.

Course gives very good info for beginners. I just wish there were more exercises between lessons. I felt overwhelmed by all the informations that I had to memorise before doing test at the end of each week. I think having more tests in between lessons would help me better memorise things.

The course is really great to learn basics quickly however it has huge drawback and that is grading peer asignments. Coursera should have courses without this. As i can not invest time in peer grading, now I can not get certficate though I have scored excellent in all the course quizes

The course is very good for a sql starter to get to know the coding world. I would recommend any starter in our company to take this course. However the final assignment is a bit confusing and peer grading created a lot of stress... that's the only reason for the 4 score instead of 5...

It was my first course in SQL and I liked it. In general, that's a good course with a lot of practice. Some things were tough and it would be better to cover them by more examples. Anyway, the course helped me to learn SQL and I'm going to explore the data world with my new knowledge.

It was a great course for introduction to SQL language in general, since I had a little background knowledge in SQL, it wasn't difficult to understand but I believe for some people, the explanation could be vague since the course lacks examples while explaining some of the concepts.

AS someone who has never taken a data science course before, it was a good start. Some of the assignments required me to seek some external sources for extra material and learning but it was worth it. SQL is such an interesting language and I can't wait to use it for future careers.

Honest feedback, as an SQL beginner I feel there should be some short quiz to practice queries after every few videos rather than at the end of every week. Other than that the course was top-notch, it went into good detail and the peer-to-peer assignment helped a lot at the end.

I like the overall look, feel, and organization of the course. It was well paced and simple to understand. I struggled at times with coding questions as some are very ambiguous and there isn't always an easy way to find guidance in the forums. Overall, though, I was very pleased.

Overall a good course for the starters in SQL in Dtaa Science filed, however I felt it could be some more hands-on oriented with some more examples, and it was mainly of lecture contents, rather things could be shown visually for a better understanding. Thank You for the videos.
