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

课程不错，基本的SQL语法都讲到还配合了练习。只是在使用IBM DB2的时候还不是很熟练。

I liked the way this course is structured and I am really happy with the kind of exercise it contains. It would be really great if more details regarding the python script was provided

It was a very knowledgeable course.

This course is best for beginners to get started with the database and sql with ibm cloud. But the content can be improved more as the assignments is concerned.

Nice Course for SQL Practise

Well explained the concepts with examples.

The course starts from the basics but progresses to intermediate level concepts in SQL, like joins and subqueries, which are required for day to day work in the Software industry.

The additional activities helped a lot. This definitely sets you up with the fundamentals. From there it is all practice.

Good

A great and solid introductory course to SQL. I recommend it to those who want to aquaint themselves with databases and sql.

It would be nice if there is a module on different type of databases and their properties

excellent course with real practical implementations.

helpful

So far excellent!

Very good intro to SQL but not too indepth

The course is really good for the beginners who want to learn SQL.

Dear IBM Program People,

Great Course. I would have preferred not waiting up to one month to get my final assignment reviewed.

That makes irrelevant the efforts a student makes in completing the course as soon as possible to start learning other courses. That is the only reason I give 4 stars.

Best Regards,

Pietro

Un bon cours concernant l'usage du SQL. Il reste nécessaire de s'appuyer sur des ressources extérieurs pour appréhender au mieux le langage.

This is a great course and I particularly appreciated the integration with Python/Jupyter notebooks. As in previous courses in the IBM certificate program, the labs were the highlight. They challenged students to answer questions using real data sets. Going from start to finish - from sourcing and downloading data all the way to analysis - was very helpful in mastering all of the techniques.

A couple of sections felt out of place: in my opinion, the optional database schema topics could become a separate course of their own, while the section on joins deserved more attention. The lecture slides, with the pictures of interconnected tables, were a bit hard to read and could do with an upgrade. Overall though, great pacing, with easily digestible videos. Highly recommend.

I feel the videos could be more explanatory and should explain some of the concepts a bit more in details. Rest everything was good especially the labs.

I found week 3 a bit confusing, but otherwise it is a very useful and well explained course!

The content is clear and useful, but the videos are not attractive, so it is hard to pay attention.

There are not enough assignments for us to learn.

Well explained, but both the quizes and the final project were too easy.

I found, sometimes, hard to use DB2

warehouse, so i prefered using other types os database.
