The concepts in this course are explained very well and are very descriptive. They are taught step by step and she also gives an explanation as to why we use these concepts and why theyre important. I was able to delve deeper into SQL and was able to acquire the basics in order to solve real life SQL problems. She is one of my favourite instructors!

SQL for Data Science course helped me a lot to learn SQL syntaxes and strategies that can help me solve real world problems. The most important strategy that I learned in this course was to understand the data, if you master understanding the data then you can easily write syntaxes. I am very glad that I finished this course and learned new skills.

Good points: Provide the knowledge from zero, Always clarify the learning objectives, Good assignments and grading system, and Final assignment with peer-reviewed system is cool!

Weak points: The number of examples is not enough, Should have a pointer on the screen to make the learner understand more easily

Overall, Impressive!

Thank you very much

Great course for anyone who wishes to understand how SQL works with relevance to data science. This course will set you up for advanced data mining using SQL. The topics covered in this course are sufficient for understanding a proper working of SQL. Other than that , you will have to practice to get good at it.

But overall great course. Kudos.

Even though this course is aimed at beginners, the assignments encourages a person to do some additional research. This simulates how a person should continually research and explore to enhance one's knowledge and experience. The final peer graded assignment was fun. Make sure you allow enough time to spend on it and you will reap the rewards.

Really great introductory course to SQL. I highly recommend taking this course for those who have little to no experience with SQL. All of the course work and material was easy to comprehend and very digestible. In addition, the quizzes and assignments were great supplemental exercises to reinforce the concepts that were taught in the course.

Today in the morning at 7:00AM EDT I was so happy that I can't imagine, Sadie made me positive and passionate in my career. Because of her, I can now achieve my dream to become a data scientist and learn more and do good in life. Hopefull! This is the best course of SQL hands down! I failed many interviews but now I am sure I will pass it.

I really enjoyed the course as per the content and the review questions at the end of each week! I have learnt a lot to build on and can't wait to practice SQL and use it in my work. I totally recommend it to anyone who needs flexible hours to learn how to deals with big data and to learn how to retrieve and be tidy with the data in hand.

One of my favorite courses on SQL so far. I would definitely recommend it for beginners as well as those who want to brush and broaden their knowledge in databases and query optimization. The instructor is highly knowledgeable and very well articulated. I have enjoyed the course so much because of the clear presentations and explanations.

The course is simple and clear for a beginner. The slides,video and notes are helpful and it guides me slowly to understand different SQL syntax and its applications. The quiz and assignment are really good platform to practice all the knowledge i learnt from those 4 courses. Lovely! Highly recommend to others who never learn SQL before.

Some of the beginning is a little too easy. The last assignment of week 4 was much more time consuing than anything else - expect to take 5+ hours if you're going to do a fantastic job. You could probably rush through it in less than 2 hours but as a peer grader, I could tell who rushed through, and who took time to do a fantastic job.

The course provides a lot of useful material and additional resources. The lessons are clear and interesting and help the students stay on track and keep learning. With a considerable amount of time practicing what I've learned during lessons, I think I have understood the underlying principles of SQL which I can use in the future.

The course was well explained. I struggled a bit with some topics like combining multiple joins and subqueries. A few additional examples in the form of a case study might have helped understand the concepts a bit easier.

The quizzes , projects were all good practice making us think and apply the knowledge we gained.

Thank you.

Coming from non technical background I have faced many challenges in past specially when dealing with big chunk of data into Anti-Money Laundering domain. Now at least I can eliminate dependency from IT team to run queries and extract data for me. I can manipulate and filter the data on my own as per the business requirement.

Lectures were greatly oriented and well presented. The content was brilliant and perfect for a beginner. It was eary to understand. The assignments were quiet challenging especially the peer graded one. Overall the course really helped learning and practising SQL and tested whether we have learnt something from it or not.

It was a great course, only thing is that it was a shame there was no explanation on how to code by yourself. It would've been nice if there had been an explanation on installing SQLite studio or something, that's what I used myself anyway. It was easy enough, but some guidance would've been nice too.

Anyway, great course!

I took a different Data Analyst Professional Certificate on Coursera, but this class actually taught the fundamentals of SQL and how it works. It made sense! This is the first in a series of four courses...Now I am excited to go to the next course rather than wanting to pull my hair out after the last program I was in.

This course was my first experience with this type of learning and it went so far above and beyond my expectations. Sadie is an excellent teacher and I found the course very easy to follow and interesting. I feel that I learned a lot in a short time and would highly recommend this course to anyone looking to learn SQL.

Great course. Final project needs some work and this course will be top notch!! For the project, it would be great if we could port the data into R or Python and do some sort of basic analysis of it. Would make it more interesting. I like the separate coding and concepts quizzes. The teacher is amazing and upbeat!

The week by week tests we have to do are very useful to apply the theory. To my first approach to SQL is a good course. For me the most difficult thing was to do the last test because I think you need to be more advanced as data analyst than to sql and I'm just starting my master in Data Science. I would recommend it.

Very useful for beginners who don't know anything about SQL. You will learn basic things that are necessary, although sometimes these videos won't be enough and you have to do little research by yourself (watching videos on YouTube and reading some tutorials). Overall it's very interesting and with a lot of practice.

Good introduction to learning SQL, data science best practices, and tools to continue developing this skillset. The lessons and quizzes are well-organized and easy to follow, as well as give good food-for-thought questions to get the problem solving gears going. Would recommend to anyone getting into learning SQL.

I completed the course and found it very helpful. Lectures are clear, easy to understand but still need to show more examples on coding. The exercises are suitable for learners. However, some questions have unclear content, making it difficult for learners to answer the questions. Overall, the course is very good.

The lectures videos are the right size. Assignments are too simple at times. Final peer-review assignment was decent difficulty and allows for a lot of involvement; it also introduces you to data analysis in a structured manner. Liked the course very much. I'd recommend it to beginners in SQL and/or data science.

I liked the way the material necessary for data analysis was presented and organized. I think there could be a bit more difficult exercises during the course to prepare learners better for final project and give them better idea what is expected in real world.

Overall, it was awesome and well designed. Thank You.
