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.
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 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

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.
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.
By Sarah S•
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.
By Martina M•
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.
By Charla S•
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.
By PETWE G G•
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.
By Ben W•
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.
By Monica W•
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
By Allen P•
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.
By Giulia T•
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).
By Vinayak D•
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.
No practice examples at all. Videos have only theorethical queries without results, so you can`t see how it works on practice. Reference to SteckOverFlow is awesome. Why should I pay money for nothing?
