I recommend this course but not as an absolute beginner to SQL as the course suggests for the following reason: after each video tutorial there are no practice exercises to implement the expressions and clauses reviewed in the video lessons and a majority of students seem unable to complete the weekly tests without considerable outside supplementation. From a time investment perspective, I recommend studying SQL elsewhere before taking this course, and then cruise through the video lessons and use the weekly tests to practice the foundation you gained elsewhere. SQLbolt receives a lot of praise and I will head there next before considering the other courses that comprise this UC Davis SQL certificate. What this course does well: the instructor, Sadie St. Lawrence, explains the topics concisely, the videos are not too long, the supplementary articles and links are helpful, the practice tests are great for practice. Areas of improvement, some of the questions are poorly worded, there should be instruction on how to download datasets and practice them in Sandbox, the questions during the videos are superfluous but I understand that it helps prevent students from skipping the videos, not enough opportunity to practice the concepts are provided.

Probably I would give it a 3.5 if there was the option, but ok, let's leave it at 4. The reason is the way the whole course is presented, you go through all the videos and once you are done with them, there is a quiz and exams. There aren't any excersises between lessons taught in the videos, where the student can practice while the concepts are still fresh. For me that was not a problem since I have experience with SQL, but I could see someone with no experience struggling.

As a final comment, the final assesment have a big flaww: The instructions are not very clear. I am certanly not the only one that had a difficult time understanding what was expected... The biggest problem was related on the size of the data that is available for the final assignment. All is limited to 10K rows which means that when we try to join tables, for example a review on the users, not all the revies exist in the review table, but in the user table (review_count), we know that there are more reviews than what we can find on the other table. I have struggled with this because my approaches and desired analysis for the second part were not possible to realize

The course covered the basics of SQL syntax, key statements and operations and some use cases to provide examples. There was also good information about best practices and how SQL theory can be applied to situations you are likely to encounter at work. There were regular quizzes and mini projects to apply your learning and test your knowledge. I did like much of the final assignment however some of the questions were ambiguously worded which made it difficult to work out exactly was being asked of me. Also one of the questions in the last part was far more difficult than anything experienced up until then which made me believe it was out of the skill range expected from the course. The peer-reviewed nature of the final assignment was a good idea but does rely on the judgement of other learners rather than someone who knows the material extremely well. It would have been good to have a combination of a timed test as well as a small guided project to test all aspects of my knowledge. This is however a very good introduction to SQL and provides some idea of what might be expected in it's professional use.

Excellent course. Professor very knowledgeable and professional. A few minor observations -- the presenter could have broken down some of the larger topics (i.e. joins into separate modules and prepared more practice assignments, especially writing queries so the students could get more comfortable with the task. Also, the alerts when a students does not write a query correctly could be a bit more explicit (i.e. which"(" they are referring to). Furthermore, one of the questions in "Graded Assignment"in the Week 4 Module where the first question did not recognize one of my answers as correct, even though it was. Next, some of the questions in both the graded and final assignments were not clearly worded so it was a bit difficult to understand what they were asking. Finally, if I wanted to repeat or pause a portion of the video, it would often jump back on to the very beginning.

On the whole, however, this course was very informative, interesting, and enjoyable. A must for anyone interested in improving their skills in both data/database management and computer skills in general.

This course was my first exposure to SQL. Much of the topics covered were easy to follow. I would have liked to delve deeper into some of the course topics. Some of the lectures were a little vague with only the static PowerPoint background. It would be helpful if the lecture was overlaid with motion pictures to help demonstrate how some of the code works in practice. The option to practice SQL on a computer using SQL Server or SQLite for applicable practice would also have been appreciated. Typing SQL code into the website isn't the same as using the actual programs one would use for work. Also, upon course completion, the Coursera website indicates this is 1 of 3 courses. However, it is unclear what course 2 and 3 are. I would like to learn more as I am hoping to utilize my economics and mathematics background in the work force as a data analyst. Overall, I enjoyed this course and recommend it to other folks if a traditional college course is not a viable option. If the option is available, I strongly suggest enrolling in an accredited, recognized university program.

I thoroughly appreciated learning a ton of SQL CONCEPTS and having the opportunity to practice writing queries and applying the key concepts in the Peer review assignment at the end of the course.

The 4 stars are because the presentation style of the educator was too boring for me so at times it was hard to concentrate on the video. It felt like the presenter was standing and reading off a script in a monotonous voice which certainly tested my patience to keep going through longer videos.

I am a supply chain professional with over 3 years of Supply chain experience in manufacturing and the Oil and gas industry and I am transitioning into a career in Data Analytics. This course is like a flame that brings into a dark room. I realised now how many concepts i need to learn in depth to truly get a mastery on SQL, which is the #1 skill i see repeated over and over on job boards. So this course just serves you the appetizer makig you hungry for more. I highly recommend completing practice quizzes and coding assignments to other new learners.

Overall this course provided a great curriculum to begin learning SQL basics as well as thinking about data in a scientific way. My only real feedback would be that I frequently had to look elsewhere on the internet for examples to understand the syntax and rules of each operator or function that was introduced. The core video lessons sometimes provide only one or sometimes zero examples of how to use the operator or function being discussed. More specific examples would be helpful. I am a native English speaker and still had occasional difficulty understanding what the instructor was trying to communicate during some of the video lessons. Many of the sessions could have been edited for clarity, especially when many students of the course are non-native speakers. Overall I learned a great deal and understand the basics of SQL such that I feel confident moving onto the next course and expanding my skillset. Thank you!

I must say the final could use some improvements some things I wasn't really prepared well for was searching for any nulls that took a huge query and the last question on the final project was kind of vague. I took this course to learn by doing, wish there was some extra help when I ask sometimes nobody responded, so it was supposed to be a three week course, but took me 4 months. I gained alot of weight during taking this course, when studying this it takes me hours on hours sometimes I can't schedule other things in the day in fear of overlapping and forgetting. The instructor was good I had to research more on my own on the different times to use subqueries vs joins. Overall it is good experience I feel this is not like riding a bike and to remember it you have to keep doing it consistently. The readings on Data science are really really long as well the readings actually take a huge amount of time.

Good introductory course for SQL beginners. Adequate content with plenty of reading to expand interest and find further references. Also an adequate pace that allows to combine learning with busy life. It allows to quickly build understanding of the concepts and their basic application to solve basic business questions as well as confidence. Sanbox practice w/o need to buy into any program is very usefull. The course delivers what it says it will deliver. Looking at others' reviews, expectation far exceeds what this course is designed to deliver in the given timeframe.

The polling questions are excellent during the lecture videos, as they keep the participant engaged and check understanding of subject. Only suggestiion for further improvement would be to split the video tutorials with some sandbox practice, instead leaving it out to the end of the section for a practice quizzes.

Overall good course with a helpful breakdown of concepts and skills needed to get started with SQL. Good structure and flow of information, which slowly builds up your skill and confidence throughout the four weeks.

It could definitely benefit from more code examples, especially in regards to concepts like date and time formats in SQL, and how to manipulate data in relation to these. Also would have been great to get more hands on coding practice before the end of the modules, as it can happen that you think you understand everything throughout the week, only to face up to a barrage of your weaknesses at the very end. Some self-study is also required, but I believe that ends up being a strength, as the course gives you the direction and often lets you figure it out.

Really enjoyed it, and recommend it to anyone starting off in this field.

Hi! I'm still on WEEK 3 of the course and I'm yet to finish the course. The course content for Week 1 and Week 2 was amazing! The explanation, enthusiasm of the instructor in teaching, the examples and the description as well as clear cut definition of each term made it so easy to learn the concepts. Thank you for putting up such a great course material.

That being said, in Week 3, the concepts get tougher so the explanation should be more detailed and there should be more number of examples. However, that's not to be seen in the videos. There are hardly any examples.

The tables and what output we get after submitting the query is not shown. Without looking at the table contents and the kind of output each type of join query gives, it's very difficult to understand the concept. :/ I hope Coursera will do something about this. Thank you. :)

The basic elements are covered well - the structure of relational databases, fundamentals of queries, different types of Joins and how to do them, and aggregate functions. In particular, I found the explanation of Group By and aggregate functions was very clear. The course also introduces some basic text and date formatting and gives you practice with all of this. One shortcoming was that the final assignment (Yelp data analysis) had a data set that was a small sample, not consistently chosen. So when you tried to do joins, you had queries that were full of nulls. And I thought the conceptual sections (beyond the how-to-code sections) were a bit over-simplified. Still, you will get up to speed very quickly with this course, get a lot of practice and quick feedback, and be ready to jump in to using SQL after completing the course.

It is very hard to follow along and understand the material in the manner in which it is presented. Prior experience is A MUST! The instructor stumbles on her words a lot and the course consists of static slides showing code / queries but does not show the output. You are essentially listening to someone try to describe code without actually doing it yourself or see the results. The quizzes are your one and only chance to get any hands on practice. I changed my review from 3 to 4 stars because of the final project. It was very time consuming, and quite challenging, but it was exactly what was needed. I had to go back and review all of the videos, download notes, and really try to understand the materials presented in order to complete the final project. It was very rewarding, and I enjoyed reviewing my peer's assignments.

The course covers the essential basics of SQL and gives you more than enough knowledge and skills to apply for related jobs, projects, internships etc. If you wish to continue learning, I think you have sufficient skills to search up syntax on your own for more advanced topics and you probably don't need to take another proper course.

Unfortunately, there were also certain drawbacks including very basic videos where the instructor only read a script and went over basic presentation slides. This makes the lectures really boring for me and I usually skimmed through them...Also, you can't really practice the lectures on your own besides the quizzes. For this, I recommend practicing on W3Schools along with the video.

All in all, I recommend the course if you're willing to put in extra work on your own.

Good luck!

This was a great introduction to SQL for a complete beginner and the only thing keeping it from a 5-star review is attention to detail. Some of the questions throughout the module are confusingly worded, at least to me, and I couldn't help but notice the times the lecture didn't match the text on the slides. Last, I don't believe peer-reviewed grading is a viable system. After grading other submissions I realized I had not done as well as I would have hoped on my own assignment, and was looking forward to reading the feedback. Unfortunately whoever graded my assignment did so rather quickly and left little helfpful advice.

Overall though, great introduction. Sadie's ability to boil SQL down to the basics was helpful and I look forward to learning more in the weeks and months to come.

Really tough assignments. Tests your knowledge of you have learned. A good notes is necessary to attempt the final peer review assignment. Good links to outside sites for reference reading and clarity. Overall enjoyed the course. Learned a lot and understood how important data is in our life and how vital a knowledge to work with it is in today's world.

Small Advice: After each concept videos please make learners attempt questions on the solitary concept alone instead of brain storming the whole weeks total concepts in one coding assignment. It helps the learners to grasp the concept more and to remember it with enthusiasm.

Wonderful course with lot of tricky assignments. Have fun guys. I heard a specialzation is on its way for this. So its worth taking it and following a path.

I would have given this course a 5 star but why I am giving a 4 star is because it doesn't show how to get or install SQL. It just delves into the program but with programming, the best way to learn is to practice along side the instructor and then pick up challenges on your own.

I had to google online and watch YouTube videos on how to install MySQL and after downloading it and actually using it and having a fill of what the actual database workbench looks like that was when I noticed my skills increased by lips and bounds!

Overall, this course is amazing and has great content! You might also want to check out other sources to learn how the syntax works for different queries you're writing among the different RDBMS out there like PostSQL, MySQL, DB2, Oracle etc.

Overall, I think this was a good course. However it could have been great with a few tweaks - I think it would have benefitted from more practise exercises during a module instead of it all being done at the end, and it would have been really helpful to see the actual code that should have been written for the answers for the quizzes as sometimes, even though I got to the right answer, I wasn't sure if I could have done it in a better way. On some of the specific pieces of content, the module that talked about date/time strings I found quite confusing, and the profiling section also didn't include enough specific examples. I did enjoy the course though, and the structure of it meant that I completed it, and found it easy to pace myself over the few weeks.

The instructor explained the concepts well and easy to understand. But starting from week 3 and week 4 the slides that the instructor used in the video is a bit different from what she provided under download folder for the slides. So, need to update the some slides in download folder for updated slides. It will be better if they provide some examples for concepts instead of showing the code. The final project was also good but it will be better if they give the answer keys after we have done the final project or something or maybe some tips after completed our final project. So that we can look and learn our mistakes from the final project. Apart from that, it was a great course those are going to learn SQL and those who are beginner for SQL.

It's a good intro course to SQL for data science. The videos are helpful but the lack of practice questions or active presentations (showing the presenter using SQL and not just showing code on the screen) made it difficult for me to engage with the course. I had to go find additional practice question resources outside of the course and frequently used outside sources to help understand what I was doing. SQLite is also terrible and frequently times out because your query took more than 3 seconds. This was very frustrating as it leaves you unsure if your code is causing problems, the website/server was busy or SQLite just didnt process in time. I'd like a more robust SQL option similar to the way Hackerrank works.
