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

This course involves good theory on databases. It makes you familiar with different databases. Further, it takes you deep into database queries and how to perform them. The best part of the course is it provides the opportunity of doing practicals on the IBM DB2 Database. Overall, it first teaches you the theory and then practical experience.

It will be better if instructor could provide more tips or attentions or common mistakes on using SQL, for example, when retrieving string results from multiple tables and joining them together, their format should be exactly same, or there will be no value though the syntax is correct. Then we will avoid wasting more time on trail and error.

I enjoyed this class. It was interesting and gave me lot of hands-on work with SQL that i needed. That being said, there were quite a few moments where I had to dig deep into the discussions to figure out how to get stuff to work with the IBM DB2 Cloud. The text/video was not up to speed with the changes to the IBM console/setup....

A good introduction to SQL and Databases, informational and easy to follow. There is a need to update the instructional material in the course to be in-line with the current IBM cloud and DB2 set-up page, new user will be lost due to the inconsistency between the instructional material and actual web page of IBM Cloud and DB2 set-up

Overall a good course, but it was sometimes difficult to get IBM's Db2 working. Some days, the database wouldn't even open and I couldn't practice. Connecting to the database from a jupyter notebook also caused errors caused by the server or database, which hindered study and practice. Otherwise, a good SQL course.

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

Some automation in the final submission review may save time. Especially where answer is a objective type. For the subjective answers always peer-review is a good option which is in practice. Otherwise, it's a great course helps someone to start their journey in SQL with exposure in IBM cloud space.

A good, but shallow, course for learning basic SQL and Relational Database concepts. Good for those looking to learn the fundamentals and start working hands-on as soon as possible. Those looking to learn beyond the basic should look for other sources in concert with, or instead of, this course.

I want to share my experience with coursera is really awesome and the course i completed Databases and SQL for Data Science is also best for my carrier and have a best content to learn DB and python. so go for it. course content is not so long or not a so small so you can lear hear very easily.

It is not suitable for beginner in databases.

It is helpful for people who are trying to use Python to access SQL, database APIs basics.

The cons are this course is too focus on how to use IBM tools, instead of problem solving or general knowledge in using Python to connect SQL by APIs.

The course is very excellent however I have faced an issue with IBM DB2cloud .At the time of final assignment submission it was not working and always showing 502 bad request ,So I have faced little obstacles during completion of my final assignment.Otherwise the course is brilliant

Good course with very useful and valuable material. However, there were times when there were issues with loading data to work on assignments. Additionally, IBM updated their cloud system, it can be challenging to follow the course directions because they are not up-to-date.

Peers need to understand the description and the submissions to review the assignments. I have been reviewed as not attempted for Problem 7 and partially mark for a completely correct Problem 9.

I don’t want any person who cannot understand the questions and answers.

It is a good introductory course for individuals who would like to understand the the basics of how to work data (Load data into a database, query for relevant data using primary and foreign keys from different tables) and understand the fundamentals of SQL

I think the course should include as mandatory the week 6 that is noly required for the Engeneer Specialization. I know that joins are crucial in many queries. If you don't know how to implement them I feel you are literally halfway in important SQL skill.

well done excellent work i am giving four because you need to improve in the areas add important points such as the schema to be used in the assignment should be similar to the connection made and time stamp should also be included in important section

Hands on LAB was helpful for practicing. Though there were too many terms to memorize that it would have been helpful to actually have a kind of cheat sheet hand out prior to each video lesson to help in understanding and following the lectures.

This course offers a good first overview of working with SQL and database systems. It relies a bit too much on external IBM tools while a more general approach, with the open to get introduced to IBM tools, would be more appropriate.

I took this course to refresh my SQL skills. In general, this is a good course, but I think there was a little practice. It will be more useful for students to be required to do more tasks and assignments for asessments.

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.

Issues with DB2 loading tables apparently due to different versions was the only technical problem encountered by myself several others (see forum) made me loose a lot of time. Otherwise this is a great course.

It will give you an idea of what can you do with free databases resourses using sql to manipulate relational databases. you'll also utilize jupiter notebooks to query data connecting the notebook to a database.

This was a very interesting course. It was harder than it needed to be due to a few errors in code, but that also made it more interesting and challenging to verify that you were retaining the information.

Course is god enough. However the last assessment is not. Misprints and not clear questions lead to disappointing marks in the end. Also other students marked assessments based on their understanding.

A very useful course with some very interesting datasets/Jupyter notebooks to work through/practice your skills. Offers a good balanced blend between theory and practical/practice. Very good course!
