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.

The instructor was awesome, whatever she taught was enough to do the assignment. I fell in love with her way of teaching, and now I will also do UC Davis specialization. Assignments were good.

The Course was quiet good & descriptive, yet it didn't cover a lot of SQL such as how to use its platforms and how to connect to database, also, the differences between other platforms.

This was an amazing course. I learned so much practical and application skills from the course. The lectures are great, as our the assignments and tests.
Thank you for a great time!

The course was pretty good for a beginner. The instructor was very clear and explained all the concepts in a very easy to grasp manner. However, the entire course could do with more coding exercises. Concepts such as joins, group, etc could be better understood if there were more exercises. Also, during the coding exercise (at the end of the week) it would be really helpful if correct answer and an explanation would have been provided. Having said that, its really good for beginners and I would and have recommended this to others.

=) Very clear walkthrough of important concepts in SQL and why use certain functions for certain tasks.
=( Wish there were more practice questions so it's more interative.
=( Also it would be great if there are more "real-life" SQL practices that involve solving for an actual question that you might encounter as a data scientist working for a tech company.
Thanks so much for sharing this with us, Sadie!

Good course for anyone starting to learn SQL but the course needs more assignments to ensure that the learners have got a good understanding of the concepts. Also, the final project is a bit overwhelming to do without prior experience in SQL.

While I did learn some useful bits, I found the course lacking. I think it could have been much improved if certain conditions would have been met:A. More practice! You don't learn a computer language by hearing about it, you learn by using it. The only practice this course had were the quizzes, and they were far from sufficient. I would expect each lesson to be followed by at least some practice. I often found myself venturing to different websites in order to practice what I had learned, and learned more from that than I did from the actual course.B. Better explanations. I found the explanations short and sometimes lacking. Moreover, at times there was no synchronization between what the instructor was saying and what was presented on screen (e.g. she was talking about products when the example presented data of employess). It's a small thing but can be very confusing. It is very important to be precise here. Again, I found myself reading elsewhere in order to better understand certain concepts, which I might as well have learned elsewhere altogether.C. Examples! Again, you don't learn a computer language by hearing about it. You learn by using it or by seeing how it is used. Whenever I'm taught something, I want to be shown examples of possible ways to use it. Examples were scarce and incomprehensive.D. Applicability. The course is called "SQL for Data Science", yet I found very little in the way of applying SQL to data science. I would expect a lot more tips and tricks and examples of real-life problems and how an actual data scientist would tackle them. There was almost none of that. There were positives as well. The instructor was pleasant, the course was pretty well structured and did provide an introduction (although not much more) to SQL. But I did not get what I was hoping for.

I'm fairly proficient in R and wanted to add a database language to my data science repertoire. Most data science jobs ask for SQL so I thought this was the perfect starting point for learning. I found learning the language fairly straightforward, especially because many SQL-type commands are built into R packages (like dplyr). My job has a comprehensive relational database but, I usually use a point and click interface to make queries- now that I'm more proficient I'll start using SQL though. Additionally, I was hoping to pick up SQL before starting my grad program in analytics so I can "hit the ground running" and be ready for classes focused on database management and data engineering. I was able to accomplish this without any question.
I really liked the course, which is not surprising given all of Coursera's data science content is excellent. The final assignment was very thorough and helped put together lots of focused questions you might encounter using SQL as a data scientist. It really helped solidify my learning. For about $60, this was a no brainer for getting started in the language.

DO Slowly, Build up. This is a wonderful course and you will not know when you have learnt so many things. The instructor is wonderful she explains things nicely. The people who have designed the course must be working professionals because Of their depth of understanding of the subject and knowledge.
The most interesting thing about the course is you will learn a few things in a module then try your hands on. you don't even need a laptop to code because they have integrated everything on the Coursera's platform. I have watched most of the videos on my smart phone and submitted a few assignments too.
and the last part of the journey through this course for me is realization. You solve the questions given in the peer graded assignment specially part 2 and for a person who Has been listening the terms like PREDICTION, SENTIMENT ANALYSIS kind of stuff , Learning a few lines of codes in SQL from this course has actually let me do them.
Wonderful course Amazing team
Thanks Sadie St Lawrence

It was really helpful. As a beginner I really appreciated that it started right at the beginning. The videos were all easy to understand and well structured. I would recommend paying for this course to get the whole package because it really helped me to do the quizzes as well to practice. I found it helpful that it always consisted of a theoretical and a practical part.
The only negative thing was the very last assignment. It took me way longer than it said it would and I had problems understanding a few things around it. Looking through the comment section it seemed like I wasn't the only one. I think it would've been helpful to have another video or text before this to prepare better for this last assignment.

It was a lot of learning - not as simplified as I initially anticipated. I learned so much, and the practice quizzes as well as graded ones provided a platform for efficient amount of practice. It leads you through a course while reshaping your mindset on technology and data, if you are a beginner, and very new at this.
As an ethnographic researcher from the tangible fields, shifting the qualitative thinking capacity trained from anthropology and ethnography enabled me to perceive, correctly, the difference of ethnography from the technology concepts, and adapt to a new mindset in behavioral data analysis.

Very engaging and active course. I liked how there were knowledge-based quizzes and quizzes that we had to utilize coding to complete as well. The peer-reviewed project at the end took considerably longer than I anticipated and was more difficult than I anticipated, however, I think this exercise was important for real-world learning to occur. Having this project peer-reviewed (and reviewing others) was instrumental in learning as well. The diverse set of learning and grading in this course has been excellent.

This course was really great. I enjoyed it and the lectures were detailed and right to the point. The example code in the lectures was extremely helpful, but the assignments still left room for critical thinking and creativity when writing code. If you are looking to learn SQL for the first time, and you already have some programming background, this will be a quick course for you. If you haven't programmed before, you may find this a little more challenging, especially the Peer Review Assignment.

I took this course without having any background in programming; I had never written a single line of code. This course is fantastic for beginners like me who saw the power of SQL and the potential of SQL to solve current business needs. Completing this course has empowered me to take more computer science classes; I now KNOW that learning a programming language is not impossible, and when one understands the principles and power of SQL, an entire new window of caree

I really enjoyed this class! The instructor broke everything down in a way that made it easy understand and fun to learn. I also thought the exercises were also very helpful in making the material easy to learn the material we had just reviewed. I looked forward to completing my course every week! Thank you for making this class so enjoyable! If this instructor is teaching another course that's relevant to Data Science, I'll absolutely be taking that course!

Simple and straightforward introduction to SQL for business-oriented/frontend-facing end users (data analysts, data scientists). Very good as a refresher for those, like myself, who have been exposed to SQL in the past but did not have much opportunity to use it. Instructor covers the course material without overloading with technical jargon, and mentions best practices, which some courses lack (material addresses the 'how', not necessarily the 'why').

I'm so satisfied with this course! Good structure, a lot of practical tasks and examples. In parallel, I solve hackerrank tasks and this course gave me everything to pass it easy.
Really appreciate final peer-review assingment, it looks close to real-life analytics and was a little bit challenging for me. But I had so much pleasure done it)
So strange pronunciation of SQL)) But I thank you a lot for this course and sharing your knowledge.

This was my favorite Coursera course so far. The instruction was slow and light enough to understand. The instructor did not present the material as overcomplicated, even if it was complicated. I really liked the additional links, and the intermittent quizzes.The modules and quizzes were instrumental in my learning because they gave me hands on practice. I look forward to continuing my learning. Thank you so much!
