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.
Well it was a short course, the assignments are a little bit repetitive (mostly in the last). The course reviews every 'practical' aspects of SQL, how to assemble the bricks while writing queries,...

Questions in the final assignment are rather ambiguous. More can be done to make the questions more specific and easier to interpret. Examples presented in the course were also very sparse and basic. However the syllabus covered the basics to get you started on learning SQL.

This is a very good and useful course to take if you work or want to work with SQL. It provides a very wide ranged knowledge on SQL. One recommendation from me is that it could be a slightly more hand-on in SQLite along with the videos so that sudents can play with the code.

I really appreciate the way SQL is taught in this course. The only limitation is that if the coding given by the student does not match the coding in the answer , then it is displayed as incorrect. However the coding might be technically right and generate the same output.

The amount of content that is covered in this course is very comprehensive. The videos are precise and very useful. The practice tests and weekly assignments are very helpful. The peer review assignment was very poorly worded and ambiguous. Other than that good job guys !

Please add a video in the course for instruction on installing any SQL Studio to computer. More practice exercises are needed in the course itself. Some of the videos in 3rd and 4th week were were hard to understand without proper examples. Overall a good course. Thanks!

For some people don't care about assignments, so they don't take the time to review the work of other properly. Two of three take time and they reviews my work and the last didn't care about and he gave me a bad score! It is not fare! I took the right time to do it well

This course is a perfect start for those who have no basis for SQL to learn basic statements and possible applications. However, the lecture videos are too short and do not provide enough examples. I have to spend much more time googling before doing any assignments.

I think the course is well designed for intorduction to sql language for data science. One more thing about the course is that I cannot open and use the sqlite. If there is a bit more information about the usage of sqlite, it will be great. Thanks for this course !

Good lecture very helpful as for people who are new to SQL. The only thing that I would recommend is to give more explanations in quizzes. I wasted two days asking for help for the support just because i thought there was an error in the settings of the website

The content was excellent. I learned a lot but I would like to share that in my experience it took more time than estimated, especially to complete the final project.
It should present a better time estimation in order to support users in managing their time.

Very good practical exercises, while the lectures are worse. Lecturer mostly reads text written on slides, therefore learner need additionally to read some information online with more examples to have more clear picture and be ready for practical assignment.

I personally found the course really helpful. I recently started working on SAS and this SQL course came in handy. I'm planning on taking a course on SAS now. I'd recommend this course to anyone who wants to get started with SQL, it's a pretty basic course.

The material in the course was good and very useful, clearly structured. The only comment I would give that I didnt like the way material was presented, you could feel that it was read not told and presenter was inexperienced with reading from the screen.

The course was very interesting and the assignments were also engaging. However, it would have been even better if Sadie would code in SQL while giving the lectures. This would have provided a better understanding of how to approach a particular problem.

It's a great beginner level class. It only covers SQLite, which means you don't get some basic statements like WITH, which I use regularly. But I did get introduced to a few new ideas, and Sadie does a fine job emphasizing working in a thoughtful manner.

As someone who's completely new to SQL, I learned a lot.
However, Week 3's content on Subqueries could have been better explained.
Overall, I recommend you the course if you are new to SQL like me. If you know a bit already, this might be too easy for you.

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.
автор: Luan K F M B•
I liked all the content, but It could have some more examples in the classes, and, in the examples given, the teacher could show us the tables we're working with, so we can see clearly what we're doing...
it's very important when learning the sintax!!

I learnt coursera of Managing Big Data with SQL at Duke before. This course needs more practices in real cases compared with Duke. It only has basic statements on using SQLlite and simple real cases. I recommend Duke's course first then this course.

The course was good. It enhanced my knowledge of sequel.
My only disappointment was there was no immediate feedback or instruction when attempting to write scripts. Perhaps a pop up which noted common mistakes when attempting to write the script.

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
автор: Mary S•
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.

Great course to get you introduced to SQL. The lessons focused on actual SQL code and statements was very good. The parts of the course that addressed practical data management and database theory were less helpful, but still informative.

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.
