Practice lab assignments were excellent in reinforcing my learning, they were just the right kind of challenging. This course has been the best one in the Data Science Professional series by far.

Clear, thorough, well-designed. Labs give useful practice, assignments and quizzes test the actual instructional content. This course is by far the best in the IBM Data Science specialization.

The lectures could be quite challenging to understand due to the technical jargons used.

it is a very good course that I have learned a lot from, however, I got confused in too many situations when trying to run queries and complete assignments. I dont know why but instead of trying to type the proper query, the course pushed me in a way to find the proper query somewhere, copy it and that's it. A very positive point was the amazing support and quick responses from Rav.

Not bad, but for me, again, is to many online tools. From my point of view, some Docker Compose with the prepared container(for bd, for notebook) will be more suitable.

Feels like lectures are being give by an AI instead of an actual teacher. Also some things get repeated in several videos.

Teaches pretty well for people like me that had none previous knowledge in SQL.
I think that could tell a little bit more about SQL outside the IBM platform.

The course is pretty easy and basic, but well constructed and very useful for those who want to get to know SQL.

Course was great but RDBS in browser was so slow that i need to wait for couple of minutes to create a table. Thankfully, doing the same in python took few seconds

This course is good for anyone who is a complete beginner, new to, or looking to refresh their knowledge of Structured Query Languages (SQL). Ideally would have liked to have a lesson on optimizing SQL queries since many queries become inefficient for data tables with very large row counts, but I understand this didn't make sense since the free IBM DB2 database they have you set up has a size limit of 100 MB. No need for optimization with data this small, but it's still something they should have at least mentioned in the course as an optional lesson. Overall, nice course for learning or refreshing SQL and database concepts.

Apart from errors in the open source tools for the hands on labs, this course is fantastic and well crafted to introduce Databases and SQL. the optional sections are useful for those without good grasp of knowledge about databases and their types. make sure to take them. The labs are good, but always there is connection problems. If they will fix this, it will be one of the best introduction courses out there.

Week 4 was a bit intense and I think the topics could have been decompressed over one more week.

Covers the basics, but might be a little difficult for a complete beginner. Manageable, but difficult. Needs more help using SQL within a Jupyter Notebook which should be in the earlier labs.
