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 course is quite comprehensive and understandable. Although the lecturer explains in a very slow fashion, it doesn't really bother me since we can speed up to 1.5x. I really like the final project that we have to solve but there are a few things to be improved: It's better to make a system that we can write queries directly while listening to the video.

I really like the instructor Sadie. She introduce all concept but on an entry level basis, which makes this course situatable for new learners. After watch her 4 weeks videos and completed the practices, I also searched for more practices online such as W3school. I feel I am very comfortable to use some simple SQL command to pull out datasets at work now.

I enjoyed this course and really learned a lot. I loved being able to go at my own pace and start the course over if my schedule was too busy. You can do practice quizzes as many times as you want and you are given opportunities with extra time to redo your quizzes. This format gives you a great opportunity to learn and at your own pace which was awesome.
This course has an amazing structure. It allows and highly encourages to think like a professional and provides resources that allowed me not only to pass the course but will also be relevant when I move ahead in this skill and career path. The assignments are also very well designed. Passing the final assignment gives a lot of confidence in the subject.

Muy buen curso para empezar a tocar SQL. Tanto las pruebas intermedias como la final te ponen contra las cuerdas y te obliga a utilizar casi todo lo aprendido. Si no has programado nunca o empezaste y lo dejaste te aconsejo tener algo de paciencia para completarlo. Entender cada video y cada paso que das. Sin lugar a dudas escogeré el siguiente curso.

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!

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
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.
創建者 Mahmoud H•
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.
創建者 Tang E•
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.
創建者 Sumana K•
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.
創建者 Jessica C•
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.
創建者 Ben S•
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!
創建者 Yoshimi K•
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.

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.
創建者 Amir T•
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.
創建者 Cedric T•
Dear teachers I thank you for this course because I took this course to understand the analysis of data sql data science and also to get ahead in my job and especially what I appreciated is the course methodology and homework flexibility that allows the learner to succeed and master. Thank you and see you soon.
創建者 ANUP S•
Absolutely wonderful course. For someone who knew absolutely nothing about using SQL, this course has helped me to understand SQL coding and more importantly understand the logic behind trying to attain the desired result. Would absolutely recommend this course for anyone interested in a career in data science.
創建者 Nidhi V S•
This is a brilliantly designed course. I was a novice in the field of data science when I started this course but now at the end, I have learned a lot. The course was easy to follow and the in-course assignments helped me practice the application of SQL. I am confident in my skills as a data scientist.
創建者 Srishti S•
The instructor was very good in teaching various aspects of Data Science. She was very knowledgeable regarding the course. Also, easy queries were maintained to solve the real-world problem as well. This course has helped me in upgrade my skill in the field in which I am the most interested. Thank you.

This course if very well organized. Our instructor explain very complex theories in a simple manner in which a person with a very less knowledge can apply. The quizzes are also designed such that the learner gets a full understanding on what's going on. I am very happy that I chose to do this course.
