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 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.

Would be better to be able to see how examples play out. The whole course is just videos made up of 3-4 slides as backgrounds. No code is ever run so you can see the queries run. I had to seek out and download SQLite and a sample DB to run test queries to practice on.

The quizzes are lot more demanding than what we're taught. Good for someone who knows the basics of sql or other coding language (python or R) and wants to go over them. Too difficult for one who has no experience in any coding language and wants to learn here first.
28. Mai 2018
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.

What would really put this course over the top would be "side-by-side" practice of the material being taught. It's difficult to go through several videos in a row and then to take a quiz at the end, having forgotten what you learned in the first half+ of the videos.

This was a good course, but as with other Coursera courses there is not enough practice of the material. The assignments are easy to do if you already know the subject being taught and very, very difficult if you are just relying on material taught in the course.

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 course can give you knowledge of basics of sql queries (at least I got), but there not enough examples of how they work and practice, not enough ability to write queries on your own, sometimes not very clear explanation or mistakes in examples.

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 !!!!
