学生对 IBM 提供的 Databases and SQL for Data Science 的评价和反馈

the course is not bad, but for the beginners who don't know anything in this course some lessons are not clear to understand

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.

Good for the basics - will help getting into SQL.

quite nice intro into databases and sql for newbies

the line fir writing code in jypiter notebook were limited to one line,

therefor writing code especially in the final assignment was a bit complicated

good to learn about new function of phythone and data analysis

wonderful experience

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.

na

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

4 stars only because I think the intended coursework is pretty good but to be honest the execution is pretty average. The course will be much better if the mentors are more active in the the discussion. Right now the discussions in the forums are mostly driven by the students in the class and it will be better if the supposedly mentors are move involved to provide support. Some of the courses in edX are pretty solid in this area and I think it really adds to the overall learning experience.

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.

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

Can do better.

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

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.

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.

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。

It was a very knowledgeable course.

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

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.

Well explained the concepts with examples.
