If you don't know anything about SQL and want to try to master it - this course is for you. During the course, I went from a person who simply had an idea of what it is and how it works, to someone who can explain how and what to use. Great course to start with, thank you.

A very good course going through all the basics for writing SQL commands. A great refresher for me as I have not done any SQL in about 2 years.

Great introduction course to SQL. Instructor was great, video lectures were helpful, and I really enjoyed the lab assignments as they helped you put into action what you were being taught. Would recommend to anyone new to SQL.

This starts out really nice, until after week 1 you find out that you need the site bit.io, which is sunset. So, before you start this course, make sure it is back up (unlikely) or there is an alternative available, otherwise you might waste your time. The clips are still helpful, but learning SQL without practice is not really recommended.

Good introduction course to SQL for people who have no prior or limited knowledge about it. The lessons are well structured, with lectures and support material in each week. The instructor is knowledgeable, with prior experience working in the corporate world. It’s evident that he knows what is he talking about but does a great job by taking no assumptions while going through the lessons and I think that’s important to understand the concepts because sometimes people who are proficient in a subject take parts of it for granted and end up rushing through what they think are basic concepts and the students finish with no idea of what the instructor is talking about. This is not the case in this course and it’s helpful. Also, the speed is correct too, with pauses, clarifications and explanations of every concept that appears on the slides.

Few additional thoughts:

-There is no need to install additional software to follow the course as the practical assignments are made in a virtual environment, which is explained in the course. It’s good if you don’t want additional software running in your computer, but it has some limitations with SQL advanced commands.

-Some lessons and quizzes contain minor errors in the queries. Not a lot but there are a few, particularly in week 6.

-The course is taught in PostgreSQL, which is an open-source version of SQL. Although is similar to MySQL or MS SQL Server, it has particularities. The reasons for this choice and these differences are explained early in the course and the material is as standardized as possible to look like other SQL versions.

-The virtual environment has some particularities on its own and does not support advanced SQL commands like integrity. It’s a flaw, not a major one, but it’s present.

Breaking down the course, my rating would be:

Instructor: 5/5

Lessons & materials: 4/5

Learning by doing: 4/5

Virtual environment: 3/5

This was my first dive into SQL and it was as smooth and informative as possible. My target was not only to get familiar with mail SQL operators, but also to understand the environment in which it is used. All this was explained in a very simple way. The course material is very good structured and the length of each module was ideal for me as a full time employee and a mother of two. Also this was the optimal balance of theory and practice for me. Alan is a brilliant tutor! It is very important when tutor describes the backstage of the processes and warns about potential problems that could be faced because of this or that action. And Alan really inspires for further learning.

To summarise, I would recommend this course to everybody who decided to start with SQL.

Many thanks!

The instructor is well informed and takes time to explain concepts. my only issue is the Bit.io was not allowing me to run DML queries which i then had to change to another environment. Overall the course was very informative.

Pretty comprehensive overview of all things PostgreSQL, as well as brief comparisons to MySQL whenever dialects differ. Done in tandem with my Masters, this course helped me immensely.

Also, and maybe this is silly, but I really liked the teacher's Hawaiian shirts, a different one for every video ;)

it's actually easy to follow

No crtificate.

I would like to give full credit to course lecturer Mr. Alan Paradise for putting together this course and for all the information he had shared. Very well structured course and easy to understand. I enjoyed all the lecutres and Labs were easy to do. Thanks to Colorado Boulder university.

Great Course! I'm new to SQL and the course gave me understanding and important practice in coding PostgreSQL. Thank you Alan Paradice, you are a very positive person! It was an interesting and useful course.

In my opinion, this course is quite suitable for people who are just starting to learn SQL. Complete learning material content even to the history of the SQL language.

Excellent course. The instructor took the time to teach SQL in a comprehensive way and the labs and quizes are very well prepared to help with the learning.

I am impressed with the enthusiasm of the instructor and the way he carried the course through out. Big thumbs up from my side :)

The instructor is great teacher, however the quiz i think should be more difficult

A very comprehensive course for the basic understanding course of SQL. Recommended

Good course to start with basics od databases and structured query lenguage.

Thanks

Very well explained. It was a very good oportunity to start SQL learning.

Very good and well structured. Good tutor as well. Thanks Alan Paradise

good course

This course was very well-structured, and Professor Alan Paradise explained concepts clearly while implementing everything in real-time, making learning highly effective. The camera view of the professor added to the interactive experience, making it feel more engaging. However, one improvement could be the lab launching system—the option was only available in the first lab, so I had to go back to it every time to launch other labs, which was a bit inconvenient. Overall, a great course for building a strong foundation in PostgreSQL and SQL fundamentals!

Good to have some basic knowledge about SQL. It's a good starting course for beginner or somebody, like me, a non-technical person, to understand the functions of SQL. I need help from the bit.io supporting team in the later part of the course in creating databases and technical functions. bit.io likes other technolgy is continuously being updated. Some queries from the course are not updated to the latest version of bit.io. Some solutions provided is in MySQL instea of Postgres.

Good intro to SQL. The bi.io coding environment was little cumbersome, but the course content is good to get you comfortable with basic and some intermediate level queries.

The content of course is quite good, but tests should be more creative and less repeated. I also had some technical problems with bit.io, there were not any instructions in course how to cope with them. Nevertheless, I got the needed knowledge and I'm very satisfied!
