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.

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.

This course has great potential, but as of February 2018, it is still not fully fledged out: the lectures focus on general SQL examples with data science mostly in the background. The part that I found the most relevant with regards to data science was the final peer-reviewed project. Sadly, the studied data set was badly truncated to an arbitrary size of 10,000 records in each table, without taking into account relationships between records, which made most attempts at any kind of analysis dubious.

There were times that I felt like I didn't understand the material enough and the examples were sometimes lacking. Also the final assignment was really poorly worded so it could be difficult at times to understand what the questions were asking for. but overall. it was helpful. If you don't know a thing about coding I would advise that you look somewhere else, since this class expects you to know the basics about coding. However if you are familiar with coding it is passable

The content of the course was good. Sometimes I got lost during the explanations, because the professor did not point to the board to help us follow what she is talking about.
The assignments also were interesting and helped us understand the theory. However, sometimes the exercises were not clearly written. I also found that there is little support in the Forums, giving the impression this is an abandoned course, which is a disrespect for those who paid for the course.

The initial classes were really good. But from Week 3 onwards, it was getting a little complex. And in the course while showing the examples, the lecture does not show the output because of which everything was bouncing off my head. Similar thing happened in Week 4 classes for a few cases. For a beginner who has not experience SQL at all these issues will badly effect their progress and will leave them clueless making them to think for a different choice of course.

The exercises were extremely helpful to practise the concepts but I struggle to follow the video tutorials. While it was useful to have the coding / working displayed on the screen, I wanted to also see the output so I know what it will look like. The Peer Review assessment was also hard to work on as some of the questions were not worded clearly. Otherwise, I do think this course met expectations and I have a much better understanding of what SQL can do now!

This is an introductory course for SQL. While the course does cover basic topics at times this feels very shallow and fast. There is a massive gap between the quality of the tutorials and the difficulty of the graded quizzes. I had to resort to hours of study outside of coursera using different resources to help me complete assignments. I would not recommend this course. There are far more thorough and free courses on youtube.

The videos were nice and easy to follow, and the quizzes were good too. The first part of the final assignment was fine, but the second part was very confusing and difficult to understand, so completing the course became quite difficult. Also, it seems like there was very little help to get through the forum for the final assignment, which just made it more difficult. Would give 3.5 stars, but I can't give half stars.

The instructor was good but could have simplified the queries and then have taught it to us.
I joined a SQL course on another portal to brush up some concepts and then came back to this course as the instructor and the pdfs weren't exactly clear. Overall, the courses were good and a little pre knowledge is required for this course. A person who doesn't know anything about SQL can't have an easy path with this course.

This is a mostly a course intended to review, that's to say, you need to have prior knowledge of SQL if you want to make the most out of it. If you're just a beginner, I wouldn't recommend it though, there are a lot of things that remain unspoken and are important. Readings are okay, but in my humble opinion they fall short to what SQL world can really offer. This, I consider it mainly a sneak-peak.

It is a good course but could be better. beginners find it hard to understand what Mrs. Sadie actually means as some lectures are missing examples to better understand. I found the prompt reading by the teacher a bit flustered too which made it difficult for me to grasp what she wants to convey. I don't mean to be rude that was my personal experience. the first 2 weeks are fine though. Thank You.

It's a nice start for beginers, the videos and the quiz between courses are good.
But, maybe you should be more responsable with the final exam, it was not so clear considering english it's not the natural language of us and not always its the same to translate and to interpretate. By the way, the database used in the last exam requieres a check, and please, enable "INSTR" function in SQL fields.

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.
