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.

I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

Good overview, and you will learn soemthing for sure. Some course notes would greatly help. Also, sometimes in the videos it could help if a cursor would highlight on which part of the slides we are currently talking about and the SQL code in theslides should always go woth the output, so that a beginner can easily grasp what is going on. Some mindor mistakes in the assignments also.

It did a good job of explaining stuff, but it is just hard to connect the actual coding with the concepts since it did not provide following up coding practice to allow the student to practice them. Instead, this course introduced a whole bunch of new concepts and you only got to practice the coding at the end of the course, it is just confusing and frustrating to follow through.

Only reason I did not give this class 5 stars is because the final project is horribly organized and very difficult to through - it doesn't test your ability to use SQL or solve data science problems, but your ability to figure out what the instructor wants.
Besides that, the lectures are great and engaging (and short, so you can't get burned out), and SQL is very fun to use!

The basic concepts and ways of use were detailed explained. The code editing tool (Notepad++) recommended by the instructor, however, is not China/Chinese friendly. I would not use that tool at least, no matter how good it claims to be, as there are bunch of other ones as good as it is. Please be politically neutral as an education inistution, both for Coursera and UC Davis.

A reasonably good course but not of the calibre that I've come to expect from Coursera. Assignments were poorly worded and clearly not thought out properly. The mentors also appeared inadequately prepared and were largely unhelpful. I think with a little effort the course could be tidied up and meet the standards I have experienced in the other Coursera courses I have done.

The peer guidance review is not required as this is a beginners course and its makes it a very dependable course on someone to review it
also i personally felt the examples thought during classes where simpler and what was asked in coding paper were challenging, making us go everywhere to check and confirm the coding . It could at times become taxing rather than fun learning

Die Abschlussprüfung ist missverständlich aufgebaut und steht in keinem Verhältnis zu den Übungen davor. Ebenso ist auch die Themeneinführung manchmal sehr holprig. Einzelne Befehle werden nur für wenige Sekunden gestriffen, andere Befehle werden sehr ausführlich ausgekaut. Die Übungen am Ende der Woche könnten hier besser ausgestaltet werden. Diese waren sehr einseitig.

Course was a good introduction to SQL and its application to Data Science. There were some more complex concepts such as joins that I thought should have been explained and more examples provided in the course as it was assumed that someone had a good understanding of these concepts for the quizzes and final project when they were only lightly touched upon in the course.

Good introduction/refreshment course. I think it needs some updates, though. There are some errors in the slides and in the quizzes (even pointed out in the forums) that should be fixed. Some assignments could be improved too, some questions are not very clear.
Minor issues apart, I enjoyed taking the course and would take it again.

The quality of the course decreased after Week 1. I understand what you put in is what you get out, but the course didn't offer any additional practice for the extra resources they provided. Also, the lectures were terrible as the instructor hardly showed any of the code's output, which means I had no idea if it was correct or not.

It was a great course and I've definitely improved my SQL skills, however there were a few things that could be improved. Practice questions and quizzes should be placed throughout the course material, not at the end just before the final quiz. Secondly, the content itself could be explained in better ways. Not always very clear.

I carried some advanced skills from Excel that helped me understand the subject better. I like non-scripted more natural story-telling like courses better. Otherwise I prefer more advanced tricks for programming. Overall, it was a simple to understand and start programming kind of course. Oriented for beginners, no prerequisites

This course was very informative and ultimately taught me a ton. That said, I would have liked there being more exercises surrounding the individual lectures as opposed to being at the end of each week. I found that I needed to pair this course with other resources like W3 and Mode to really lock down SQL functions.

Some of the video lessons did not cover the material that well, or were pretty difficult to understand without context. Most of them were fine, but I had to do a lot of research myself outside of Coursera in order to answer some of the quiz questions. Maybe this was the point however...... still frustrating at times.

This course is bad structured - the rule from simple to complex is not respected. Focuses more on theoretical knowledge. Only suitable for beginners to familiarize themselves with SQL.
I recommend read the book: "Beginning SQL Server 2005 Programming" (by Robert Vieira) - it best for your starting in the SQL "world".

The course is very good for beginners but you need to do your own homework. No actual coding was practiced in this course so I had to learn it on my own. Also, got very confused with understanding RDBMS and differences between SQL/SQL lite and etc. Overall, course was informative and helpful in learning SQL.

Targeted to business people - explanations might feel unsatisfactory if you're more of a programmer. Final assignment took me a lot longer than expected as it required solving problems for which the course have not prepared me - the optimists will say that's a little of a real life learning experience.

It was good content but I wish after each concept or syntax, there was a sandbox example in-between videos cause it will help understand better and in terms of syntaxes not tested in the final review, we might have forgotten. Also, the peer-reviewed assignment was a bit much for my learning objective.

I feel the knowledge shared in the course was not extensive and also the lessons could have been more practical. Since I have already had hands on on the SQL DB's before, it was less of a challenge for me but overall content and the topics covered were good. Only if it could be more elaborate.

This course is OK. But the problem is mentor seldom answers your question in the forum, so once you encountered any problem, it's hard to continue. Also, the elaboration in the lessons can be improved with the aid of the output table, since only showing the code is inadequate for beginners.

Assignments and practice quizzes are great. Lecture videos should include ER diagrams because without them learners need to imagine the tables and application of each topic discussed. Also lecture videos should include more examples of each SQL function for better understanding.

I found the final peer-review project to be a good challenge, but disproportionate to the challenges that preceded it. The material is fine for a foundational course but I felt the instructor really didn't add any value beyond what reading from a page or a slide would provide.

The course is interesting and really focuses on the basics, so it's good for people who know nothing about programming or SQL. I didn't like the final assignment, though. I felt it was too difficult compared to the content of the course and the Forum wasn't very useful to me.

This course teaches the very basics of SQL but in the final assignment gives real world problems, that was never mentioned in the course span. How to use the queries for analytics and gathering data and coming to some conclusion, these things are not available in this course

I feel that this course strongly lacks of explaining the commands with real code sessions. Just being sat watching the Lecturer's explanations about the purpose of the commands without coding becomes a little boring and may turn out in doubts in the programming assingments.
