Comentários e feedback de alunos de Databases and SQL for Data Science da instituição IBM

I am not quite cool with the guide to grade peers. The exact answers were not cited.

The course provides an introduction to SQL but some arguments - such as basic syntax - are only presented and not explained in-depth.

On the other hand, the second part of this course features very interesting labs.

Muy buen curso!. Muy recomendado.

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.

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.

Covers all basics of SQL and methods of accessing of SQL with Python.

A great course about SQL and Databases but the final assignment should have been about writing python code to access database and analyze data, as shown in one of the videos where a pandas dataframe was created. Instead, the assignment made us write SQL code inside Jupyter Notebook. That was not needed at least as far as I am concerned. If we had to write SQL, we could have just done it on IBM Db2 Cloud.

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.

As someone with zero experience with SQL, this was a solid introductory course. At the end of the course I understood many core SQL concepts and was even able to do some coding without any help. The only negative aspect I experienced was that the course used some functions that only exist in the IBM cloud that the course uses, but this shouldn't persuade someone to not take this course.

gets hard really fast from week 3

NICE

need to to updated. details regarding IBM cloud is messy and outdated. take to long to connect the cloud. videos slides are of bad resolution. instructor voice not clear

Can do better.

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

Good course for beginners and very good practice content.

Um, equips students with the top range basic knowledge

The materials are good but it is difficult to get help if needed.

He tenido problemas con la herramienta Labs

Very basic course that teaches you the bare minimum of SQL to get started.

It will we more helpful if they provide more live examples with every execution of a SQL query

One of the best in this specialization

only for beginners

Very good course. However, I didn't like the fact that this course uses just the DB2 framework of IBM.
