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.

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.

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 course was comprehensive however, it would have been more beneficial for the student to practice writing queries during and after each introduced topic. The first time students write a query is the very end of week one after watching videos.

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 !!!!

The biggest issue is the lack of practice . They try to stack on lot of things and ask a quiz at end of a week which is the only mean of practice. Coding doesn't word that way atleast could have given some practice after every lesson.

Quizzes and assignments require a lot of knowledge not actually covered in the course forcing you to search for information elsewhere.
Questions are not clear in many tests creating incorrect answers which are not of the learners fault.

The course teaches good information but many of the quizzes involve information that was barely (or not at all) covered in the lessons. It would help if they fixed this or were at least more active in the forums to answer questions.

The course is not bad but, and this is a big but at least for me, they do not provide DBMS to practice with and no practicing material. Also, some of the links provided to get more info about different topics is way outdated.

The quizzes and readings were helpful. The lectures were helpful for some problems and for some they were just too long without containing multiple examples. The peer review assignment was the hardest out of the whole course.

This course is okay but I feel like they need more practice queries not just a test and you never got to try it before also the questions need to be better explained. Other than that I feel like I did learn the basics of SQL

I learned some basics about SQL and enjoyed it, but I think there wasn't enough practical instruction about how the code is used. It made it hard for me to figure out how to get the data I was asked for in the assessments.

This course gave a really strong overview but some of the questions in the assignments were ambiguous/needed clarification. From the discussion boards this has been the case for quite a few years without being addressed!

The course vidoes were really nice.
The wording of the exercises is frequently confusing, especially in the peer-reviewed assignment. Many question cannot be answered with the tools provided (i.e. inference, correlation).

THERE IS BUG IN YOUR PEER ASSIGNMENT SUBMISSION THAT THERE IS NO "SHARE LINK" OPTION GIVEN AND IN YOU HAVENT MENTIONED ANY WAY TO DEAL WITH THIS PROBLEM. IT IS REALLY FRUSTATING AND THIS PROBLEM SHOULD BE RESOLVED.

Course materials are good, but wish they provide the actual SQL code in answers to quizzes and assignments. Simply providing whether my answer is correct or not is not enough for me to know what I did wrong.

course was really good and understandable for some beginner like me but at same time I think that more coding exercises were required
ONCE AGAIN THANK YOU FOR IGNITING THE INTEREST TOWARDS DATA ANALYSIS IN ME

The general structure and idea of the course was good; however, there were many times when the script/questions were worded badly and this was sometimes an issue when it came to understanding the content.
