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

In the intro to data science specialization, this course is a relatively steep step up from the previous one 'Data science methodology.' Perhaps obtaining some basic understanding of Python prior to taking this course would help

Overall the course provides the concept of SQL and a great picture. Just with technical issue in the Peer-Graded Assignment, causing spending loads of time to find out the solution, which those time could have been saved.

This is a course with a lot of information, but the tutorial is not complete, resulting in a lot of time wasted in the debugging environment. The problem is difficult to solve, which makes me very frustrated

If you have zero knowledge about database and SQL...this should be the right course for you..like me...however, i feel like the course is not very structured and lack materials like questions and exercises.

First student did not check my submission at all gave 0 for all of the questions. I really felt sad because I did correctly for the project. I wish Coursera will do somethings for those mean act.

the course is good but the way they teach you is not as good as other IBM courses it was bit confusing for me where to write the code etc the instructions were not as clear as they should be

Useful course, but the instructors aren't engaging enough in my opinion. I only really felt interested right at the end, when I was trying to work things out in the final assessment.

Could not get the dataset from the assignment, always threw xml error, had to go to some other guys github profile who completed the course, thank fully he attached the dataset used

It should be stated that the exercises need to be completed in Watson Studio because there are errors with the Lab tool. I lost a lot of time doing this module with these errors.

Not super clear and struggles a bit with accessing and connecting to the DB2 I think the examples should match what is on the assignment and really break down the query language.

The labs in this course did not work. This led me to using external platforms for my assignment which took a lot of time to configure and install relevant modules and libraries.

T​he content of the course was good but it should be updated and coorcted. Especially in week 4 I spent more time working on Labs to work than actually working in the Labs.

The speaker in the videos goes too fast. The hands-on labs are very useful and were my primary sources of learning. The videos didn’t help much with the learning process.

The Jupyter Notebook portion was difficult to setup. The instructions for the Jupyter Notebook were incorrect. I had to rely on forum comments to fix the problem.

The environment is difficult to set up. For someone who knows SQL and has worked on other platforms the IBM Cloud and workspace are difficult to set up.

Content is very good. Problem is that there was many problems with apps/launchers. Many others have had similar problems based on the comment section.

The course is good, but i think that you will provide a platform to practice while watching the videos. In some examples the data base is not upload.

A little to none explanations, very easy quizzes. Low quality slides. Good if you want to remember lines without understanding what they are doing.

Learnt a lot about connecting database from python and how jupyter notebooks are useful.

Please mention IBM DB2 only, if it covers only IBM DB2.

Thanks

The lesson and video itself is okay in general, but the bugs for the labs and assignment is what makes this course very annoying and time consuming.

t​he third party tool failed and it was incredibly frustrating to try and move everything to Watson Studio. Once I got that going tho it was fine.

Getting the right syntax for Python and SQL together was really tricky/difficult. I wish there were a reference book/website for additional study.

The basics were easy. The hard part were the instructions in the course didn't tell you all the steps that you needed to do to launch the labs.

Some of the documents which are referring to IBM cloud are outdated. Otherwise this course is really good some one like who is beginner in SQL.

The course was pretty dull in my opinion. My overall thought is that they are trying to impress the student rather than teaching the basics.
