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.

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 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!

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.

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.

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!

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.

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 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.

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 give it three stars because I did learn a few things.
I think my only recommendation is to add some more practise coding before the quiz available . For example, after we finish a video, have a practise code since coding is learnt by doing more often than anything.

This course is great at getting you started in SQL. The complexity of the assignments however exceed the practice questions available. Further there are not enough practice questions to become fluent in using the concepts described. Feedback: more practice questions.

I think this course does not provide opportunity to learn sql practically. It only gives the theory of sql language, which I think is not sufficient to get the whole idea. Another thing, the quiz and questions are way too harder compared to the lectures provided.

I think some parts are not explained well and lack of examples, furthermore complicated topic are treated fast and easy topic are treated in a deeper way. I found myself in difficulties and there isn't a way to ask a mentor more infos about the topic.

This is a basic SQL course. I'm not sure why it is called "SQL for Data Science" other than that is a catchy title. I took this course to refresh my SQL skills. It did give me an idea of where I am weak, but I don't feel I achieved my objective.

El curso fue muy básico.
En mi opinión hubiera sido mejor si los contenidos de las semanas 3 y 4 fueran más prácticos.
Las preguntas del examen final tenían una redacción muy pobre y ambigua, y no había mentores encargados de solucionar dudas.

After the 2nd week, the instructor just introduces new concepts and does not explain the working of the algorithm. Also, more or less the video length should increase and more examples should be discussed.
Overall the course is great !!!!
