Was in need of a class to get back into database and this class was just perfect. I wouldn't say it's for a complete beginner or at least not for me. I was glad I had one to two database classes under my belt. Otherwise I would have difficulty following the class. The final assignment was tricky in it's wordings. But it's doable as long as you have watched and followed all the video. Sadie, the instructor is a great speaker and is very clear when she speaks. The best takeaway from this class was the very last video from Week 4, where she talks about lot of good practices one should follow when programming. I will keep it in my mind, definitely.

I really enjoyed the course, I think it covers the basics pretty good, as a first time using SQL I think I got a good grasp over the topic, exercises and materials were simple and easy to follow. I personally enjoy the professionalism of the teacher, she was very sweet and funny, but at the same time during multiple videos it was really hard for me to follow on what was said because the way the teacher spoke felt very unnatural, as if it was being read for the first time as she was trying to explaining it, making it very distracting and difficult to follow along.

Overall I think it's a great introductory course to SQL!

As can be seen in the discussion forum, the course is not really so well designed. I found some difficulties during the process even if I have learned programming before at intermediate level. The language sometimes is confusing. The lecture examples in the last two weeks weren't helpful in understanding the concept and improve coding, though the coding test is not hard to pass. The course has improved according to the discussion but won't be so helpful if you really want to get some solid skills in SQL. I came for this course for prerequisite and I actually studied at UC Davis before, so a little disappointing.

There is a lot of good information here. It is a good starting point. I felt like I learned a lot. However, it is clear the instructor is reading from a script, (not normally a problem), but often their cadence and speech pattern are off because they are reading. Also, the assessments don't always obviously align to the instruction. There are often questions that tie back to single sentence statments from the instructor. I would highly encourage any student to suppliment course material with other sources of information to ensure all of your questions are answered.

That being said, I am glad I took the course,

The lectures are fantastic but the final course project was a nightmare that was poorly worded so that you had to spend a long time trying to figure out what the questions meant before you could attempt to answer them. Also the database was restricted to 10,000 rows which meant that when trying to answer questions there were so few relevant results from queries you couldn't do much. This resulted in even more wasted time. There was no mentor help on the forum that was actually useful - other people had asked questions based on the same issues and the responses were of no help.

The interface, video demonstrations, and lectures are good; however, there is a lot of information; its hard to go back and review the information unless you re-watch the videos; there are no handouts or other notes you can reference. The quizzes and assignments are difficult to complete due to some errors with the quiz content. There needs to be glossary of terms that the learner can reference during the quiz. I'm only in week 3, so maybe the remaining weeks will get easier now that I've practice with SQL syntax a little bit.

The course content overall is very good, with assignments being appropriately challenging and thus facilitating learning better than some other introductory Coursera courses. That said, the final assignment in Week 4 is an overkill, and the estimated duration needed of 2 hours is a severe underestimation, especially taking into account the fact that it is also peer-reviewed, requiring not 1 but 3 reviews. If you are taking this course with a deadline in mind, do leave plenty of time for the peer-reviews to come in.

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.
