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.
A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

Perfectly prepared. Some tasks in the assignment were boring and tedious (listing number of rows for all tables; getting the non-null attributes).

Excellent introduction into SQL. The assignments and final peer-review project were great tools to problem solve and practice the skills taught.

I loved the way Sadie delivered important points without taking too much time. She gave just the right amount to details required to get started

El curso fue muy bueno, muy claro. Aún así me parece que estaría bueno agregar más ejemplo en los videos, principalmente para las semanas 3 y 4.

A good introduction to SQL with interactive videos. Maybe I will improve the playground a bit so we can practice more queries along the process.

Goor refresher or basic start. Personally I found the use of http://www.sqlitetutorial.net very hepful for this course, more so than the slides.

The questions in the final assignment were quite difficult to understand and the overall course took longer than the estimated amount of hours.

Great course for SQL beginners. The course takes us through all the basic syntax, thus helping us develop the ability to query large datasets.

The course should have also provided an opportunity of code along with the videos. And output of all the the codes in the video is not shown.

The course was a great introduction to SQL and the peer reviewing process is a great initiative. The course was well paced and well designed.

Worth doing. Perhaps i missed more elaborate query examples and devote more time to the creation and reading of other (external) databases.

I think videos should have more information, as some questions are such that finding answers is not straight forward.
But very good course!

The final assignment, at certain parts is not very clear maybe it's time to update it based on review and repeated question from the forum

Bon cours dans l'ensemble. Bonne structure et plutôt pédagogique, mais le test final est un peu compliqué par rapport au matériel couvert.

Overall good, the questions in the assessment were confusing at some points. I would look at editing those to be more specific to the ask.

Overall a great course, however the dataset provided for the final Peer-graded assignment was incomplete which cause me some frustration.

Great lesson even for totally newcomers. Though quizzes are sometimes tricky and have little differences in the things you get taught.

Nice course with good pacing. Though it is a bit simple and going through other functions like window function will be really useful.

Lectures should be more engaging and easy to visualize.Some parts of final assignment were vague.But I learned a lot,that's for sure.

It was good for who start the learning for the 1st time.For the beginners it helps a lot for their skill to understand and to learn.

Puede mejorar en la cantidad de ejercicios prácticos que sea realizan durante el curso, esto facilitara la dinámica de aprendizaje.

Some glitchy issues with the quizzes, etc. and some funky results in the rubric for the assignment. However, overall quite useful!

I would add a simple SQL queries to write when listening to the theory part of the course. A simple example to write or something.

The Course content is awesome. The instructor explained the SQL concepts very well. Best place to start with SQL for Data Science.

Overall it's excellent. However, there is no introduction to the software installation and this frustrates me a lot as a beginner.
