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.

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.

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 !!!!

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?
By Burhanuddin S•
Would definitely need to watch Youtube videos to understand the course fully.
Good assignments but the videos are not that great and too much time wasted in learning objectives. Too less examples given
By D H•
Good program for beginners. Peer review assignment needs to be updated. The assignment is not graded by instructor. Certification means nothing because anyone who pays money will eventually get it.
By Huong D D N•
Overall, it's a great course to be introduced to SQL without any background knowledge. However, lectures in Week 3 is hard to understand, which I need to seek for other sources to learn on my own.
By Pratyush A•
The course gives us the basics of SQL only wrt Data Science. It does not tell us much about SQL. Would have liked if more information was given on SQL and how that works. All in all, good course.
By Weiyang T•
Certain quiz questions were unclear. Final peer-review assignment had unclear/ambiguous questions that didn't fit with the data in my opinion. But content is useful. Delivery could be improved.
By Ibrahim N•
The course is very well planned with all the basics required to run a query in SQLite. But on the other hand, when it came to the last modules the class just takes off with very few examples.
By Yi W•
Strongly suggest adding more example code and its running result which will make more sense for beginner. And more exercise problems as current Quiz do not cover all the points in the lecture.
