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

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.

Great online course if you need to refresh your SQL skills and learn more in-depth. A lot of practice during this class and materials, resources given to link all the dots: DB, SQL, Python. The Course is well explained and quite clear. The Final Assignment looks more complex than what it is.

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!

Much important instruction was missing which lead to a delay in submission of the peer assignment. Various errors popped up which had no solution in the discussion forum also. Kindly look into it.

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.

Overall is a nice course. It was a bit confused because Handson Lab related to each other. It would be nicer to have a short remind from previous labs or better to keep labs independently.

Course was well organized, I found the lab exercise to be useful in learning the material. The quizzes and final project were fair and tested my knowledge of the concepts. Great 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

Good content. I have learnt a lot :) Please improve the uploading files for the tests. There were several loading errors coming from the files which should not happen at this stage...

It was good for basic knowledge of SQL. It would be better if we could understand more on Joins, Grant functions. But thanks for the great work. It was really good for me personally
