The instructor is really boaring, as if she is reading from a script.

Really disapointed.

Terrible. You can tell that all the instructor did was read off of a script.

The requirement is unclear for the last project.

This course is horrible

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 Coursera

Thanks Sadie St Lawrence

Fantastic course, Outstanding Instructor, quizzes and coding practice always relevant to the subject matter. I thought the BETA Sandbox was a wasted of time becasue I could never get it to function (and then I discovered I didn't need it anyway). For other Mac people (like me) the Notepad++ the instructor mentions in one of the early videos is a Windows only thing. If you have Parallels, it won't matter. If you prefer MacOS, give SQLiteStudio a try. It was free at GitHub and worked well. Most of the data coding examples in the coding labs come from the Chinook.db. The instructor uses some version of the Northwind database for SQLite. Then, there are some other videos that I really don't know where the data came from. All of this is to say that this course would benefit GREATLY if all databases used in the course were availble to students from the start. Then again, you may enjoy digital treasure hunts to find these things for yourself. Cheers! BEB

Excellent course to begin to understand the basic clauses of SQL and understand how to structure them to generate clean code. The teacher provides excellent examples of codes that programmers face every day, just to highlight some skills of the course, I want to say that the way the teacher teaches the clauses' CASE ',' WHEN ', WildCards,' COUNT ',' FROM 'and' SELECT 'are highly professional as it explains them in such a simple way that even beginners will understand. I want to say thanks at the UCDAVIS team and teacher Sadie St. Lawrence for doing such an interactive and professional course, something that I love is that the teacher is always in the videos explaining all the topics and in general the exercises, this is very professional already that other courses only put audio and slides and that character that teachers bring to classes is lost. Thank you very much for allowing me to learn with you. Best, Camilo Mejía-Rivera

This course has been an incredible opportunity to polish my SQL skills, and I’m deeply grateful for everything I’ve learned. It has not only solidified my understanding but also boosted my confidence in working with data. I’m excited to apply these skills as I pursue a role as a data analyst or data scientist. I look forward to putting this knowledge into practice, tackling real-world problems, and continuing to grow through hands-on experience. I also recognize that learning never stops. I plan to keep practicing SQL regularly to ensure my skills stay sharp, and I’m eager to expand my knowledge by pursuing certifications in complementary tools like Power BI, which align perfectly with SQL and data analysis. This journey has reaffirmed my passion for data science, and I’m excited to see where these new skills will take me. Thank you for this valuable learning experience!

I thought this was a very good course for an introduction into what SQL is and how it's used. The video lessons are presented well and mostly easy to understand. By the end, I felt like I had a strong grasp on how a data scientist/analyst approaches and uses data to ask questions, get answers and solve problems. The best advice I would give to someone interested in taking the course would be to really be ready to practice on your own and try to apply the knowledge learned outside of just doing the lessons. The lab sandbox they provide is a great tool and there are an abundance of free resources available online. I found that the more I practiced and experimented with the coding on my own, some of the concepts really started to sink in and I learned from mistakes.

This course is very well-designed. All the concepts one will require to work on a database are covered. The explanation of all the commands was very easy to understand. The quiz in between the videos were helpful to test the knowledge. Also, the coding quizzes are amazingly designed. Those have questions starting from easy to difficult level. The final assignment was a mix of all the concepts covered from week 1 and it was definitely a good one. Peer assignment review was a nice idea. I got to see how different people would write the same query differently. The logic of the query was same but the way of writing it, the formatting and the easy-to-follow method were some of the points I will be taking away from it. Really a great course that Coursera is offering!

I really like how the instructor's giving lecture. I also like that each video has questions along the way. It keeps me interested and focused with the material being presented. One thing though is the peer review project at the end. I thought more detail instruction on how to get data set were given. Overall, I really like the course and I think the time was well spent. I am happy to get a free certificate that I can share on LinkedIn. I have no background on data science in college (my major is quantitative econ), but my interest has shifted toward data science a lot and I slowly build my skills on it. So having a certificate to update on my LinkedIn profile will help me prove my network indirectly that I have developed my knowledge in data science field.

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.

I would highly recommend this course for anyone that is thinking about SQL and how it works. It is straightforward, clear, and a slow enough pace that getting through the course didn't feel stressful. My only complaint is the Final Quiz. The site is coded so the text boxes for your answers also has up/down buttons if you wanted to click to an answer. HOWEVER, if you use a scroll wheel on your mouse or scroll, and HAPPEN to scroll over a box that has an answer, IT WILL CHANGE IT! Please, please, please, double check your answer boxes before submitting and make sure to click outside the box so it's no longer an active field. I learned this on my third try because it kept changing my answers :')

Very well structured class that's right for anyone that's curious to learn and develop fluency in SQL starting with no formal background in SQL.

Instructor: Sadie's style of explaining the concepts and spirit she brought to the class made it an engaging experience.

Course content:The course project was well structured in that after completing it, it left me with a basis to have confidence that I can take a data set and work with it with some structure and depth.

Time & Effort: I went from start to finish in about 5 sittings spread across a week when I was on a break. The pace felt easy and I definitely feel like I can "think in SQL" now.

I took this course with basic knowledge of SQL, that is, I had experience in programming in the MySQL language. This course helped me understand more about databases and learn more about the structured query language operators used. I created a table with data for competently building queries, and therefore the code that was given in the lectures had to be adapted to my table. But you can download the Chinook Database in the public domain, as many examples are written for this data. The training is conducted in the SQLite language, but also tells about the features of other languages.

Have a nice course to everyone who wants to study it!

This is just one of those courses, everything about it screams professional. The slides are concise, and mostly provide all the content of the lecture itself, the instructor is great too. However the real gems of this course are the Exercises/Coding Assignments. Every question is varied, and at the end of the course, you will yourself learn a few neat tricks on Joining Tables, Grouping multiple data, and Complex Subqueries.

I would suggest to include a few more examples, for things like Self-Joins, Grouping, and Operations. Keep in mind, this is more of a beginner course, but it covers enough topics to dive into Analyses of your own!

This is such an excellent beginner SQL course.If you are seeking hard challenge however, prepare to be disappointed. The course just teach queries in SQLite but does not go in depth regarding data types nor table creation. This is because this course only teaches the fundamental skills of data scientist - to query and analyze data, not create database.The quiz and assignments are actually very easy, but if you make it complicated then you will go down the rabbit hole. The course is supposed to be fun and motivates you to learn SQL.I highly recommend if you know nothing about SQL or Data Science! It's a really good intro course!

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.

"I absolutely loved the 'SQL for Data Science' course! It was exceptionally well-structured, and the content was explained clearly and understandably. The course not only provided a comprehensive overview of SQL but also demonstrated its practical applications in data science. The hands-on examples and exercises were precious and helped me gain a deeper understanding of how to work with data using SQL. I highly recommend this course to anyone looking to build their SQL skills for data science. It's a fantastic resource for both beginners and those with some prior knowledge of SQL."

It was a refreshment of my SQL knowledge after 5 years.

But this course is the best so far! It is very interactive with a lot quizzes, questions and assignments.

The best part is the last section where you are to considered a data sciencist/engineer.

You need to analyze the data what you want to show. After that you are going to specify which data it is required and to write the code.

What new was for me is the 'JOIN' concept. Very interesting and a lots of positive 'frustrating' fun.

Sadie explains it very well.

So, my compliments Sadie....

Kind regards,

This course is excellent. Very weel structured, especially for someone completely new as myself. I thought it would be very difficult to follow but instead I was able to follow through and completed.

It actually helped me to land a job at Google as an analyst :)

The only thing off is the last part of the final assignment. As many folks mentioned, i had the feeling that we were tested on things we hadn't be taught or at least it needed a more analytical/mathematical way of thinking, which if you don't have the relevant background it's hard to have developed within a short course.

More than just a tutorial on SQL (SQLite) commands, this course provided a useful overview of the history and application of RDBMS where SQL is applied as well as a selection of readings about other kinds of data settings that will require NoSQL tools. Found that the videos and quizzes included both content questions to test knowledge as well as SQL coding assignments. Even though it was online, there were opportunities to interact with peers. The last assignment in particular challenged one to put it altogether with SQL coding work along with analysis of data.

This mooc is really good, Sadie did a good job

positive point :

good structure

well constructed quiz

The practical cases allow you to apply the different tools

the slides in the videos are synthetic, with the objectives always stated at the beginning and a summary at the end of the video

negative point :

the questions in the final assignment (Data Scientist Role play) are not always clear

the codes are not detailed enough sometimes

I would have liked to have more details on the Many to Many relationship as a conclusion I recommend this mooc, offers good skills in SQL

This course was structured quite well! The material was easy to digest and paced well, also. I began the course knowing virtually nothing about SQL, and now I can confidently say that I can query a database utilizing ER diagrams, joins, cases, subqueries and a plethora of other functions to find the data I need. Some of the quizzes had questions where it was unclear what was being asked, so they could use some tweaking, but in the real world that happens all the time so I'll chalk it up to extra practice at interpreting prompts. Thanks for teaching me SQL!
