I didn't learn anything other than basic theories and basic practice, which leads me to have another better course from another platform ofc.! I am more angry to Coursera, as it took money automatically, without even emailing me or any other information before taking that money. I had finished the course and they took money twice. they didnt inform that i have to cancel the course even after finishing! why would they? ! this is using people, nothing else. Just WASTED my time and money. that's all.

This was a shockingly different approach to teaching a software language. I did not enjoy the style whatsoever, and found myself constantly seeking outside sources to understand what was glossed through. Unless you have a strong programming background, I would not recommend this particular class. Instead, seek something where you will complete SQL code yourself, with explanations of syntax, structure, and purpose, specific to the format you will be using. You'll do yourself a favor by doing so.

This course gives a pretty good theoretical overview, but is not practical. There are limited exercises and often the examples are poorly explained. Someone starting from ZERO SQL experience will not succeed in this course. You would be better off going through https://sqlzoo.net/wiki/SQL_Tutorial and then returning to this course.

Lectures were stilted and repetitive, some of the exercises were poorly thought through and the peer-grading is a joke, with people grading me as having got questions correct, when having seen the answers I now know I got some questions wrong! Questions from peers went unanswered in the forums.

It stars strong, but on weeks 3-4 it lacks comprehensive examples and guidelines, and that makes you feel lost. Also, the final assignment is very hard, and it asks things in a non-comprehensive manner, which makes you spend a lot of time until you understand what they are asking you.

Considering how hands on learning a language like SQL can be, this course does a lot of info dumping about the theory all at once instead of embracing the practical approach. This makes the course a lot more taxing than it has to be.

The teacher has really good knowledge of SQL and I really respect her for that, but as someone who is not familiar with SQL finds it difficult to give quiz without any side by side practice of the topic

This is not a beginner course, it is very high level with little time or explanations spent on each topic. The quizes expect syntax that has not been gone over in order to correctly answer the questions. I received better explantions for what was needed from W3school brief high level explanaton then I did this ocurse.
The instructor tends to stumble over her words alot which causes confusion and the examples within the presentation are not really clear as they arent based off real world, just table 1 table 2 etc.
I debated if I should review or not as I wonder also is this just not witin my leanring style, but reallized in a course of this type it should fit a variety learning styles as the Google courses do.

Material was good, but the staff is why I'm giving 1 star. Finished the course and submitted my final assignment for peer review, it has been "in progress" for 4 weeks, this is not acceptable to delay learning progress. Staff should have a way to monitor the assignments time and resolve. We respect your time, please respect ours.

There are not enough examples in between the lectures. It's impossible to remember all the SQL commands if the course does not provide practice questions before the quiz. Also, the instructor keeps moving around while she's explaining which makes it hard to focus, and the course is not interactive at all.

Be aware that for many students the sandbox that is necessary for completing the quizzes at the end of each leasson does not work. This is a known issue but so far the lecturer has not commented on this

This course only shows the syntax, but didn't teach how to write. I'm still very confuse about the syntax after taking this course. NOT RECOMMEND

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

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

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.

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.
