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.
I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

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.

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

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.

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.

If the instructor would've run the SQL queries it would have been more understandable overall good course .Just if the instructor actually write query on a system and run it it will be more beneficial for students. Nice course Overall

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.
This is a great SQL course! I would love to see more case examples in each videos of the week? In some videos, it felt a bit confusing to understand the spesific cases in which we should use the joins, unions or other statements.

The course was overall very good. One thing which I felt can be improved is the pace of the modules. The level towards the end shot up very quickly.
I would definitely recommend this course for anyone who wants to start with SQL.

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

its much easy to understand the queries with the simple explanation . Best for beginners but I suggest to go through sql and how queries work before starting this course so that it will be helpful to quickly grasp the queries
автор: Mert y•
I think the course need more practice quiz and all practice code quizzes answers should be put.Because If I don't remember wrong, Week2 and Week3 practice quizzes answers were not put. Apart from these the course is so good.

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 :)
