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.

I think there were some explanations which were confusing but I did learn a lot. I wish the course utilized the sandbox for questions. While starting out using the encoded SQL text boxes on the quizes was very easy, going into the sandbox I think would replicate a more typical environment. I understand simple structure of SQL, but I have no idea how to use it outside of this course.

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.

Si bien es cierto la materia del curso es buena, los videos se vuelven aburridos ya que solo esta una persona ahi hablando y hablando, no se hacen practicas durante los videos o mostrar ejemplos auque sea. A mi se me dificultó mucho aprender porque no me quedaba claro y sin practicar es muy dificil. Al momento de hacer las pruebas tenía que venir de 0 sin practica.

Very well structured, BUT the final project is not correctly done. The answers they expect are not the correct ones due to mistakes in the dataset. It also tests very simple things and does not really reflect what one should've learned in the course. If the final project were better I would give 5 stars as a good introduction to SQL

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 in General was good, but i found the way to give you the knowledge wasn't the proper way. It was very complicated to ask for help in some exercises or to see some programs. In my perspective I found SQLITE a waste of time, not really straightforward, confusing to operate, not my choice to process data.

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.
