Amazing course for beginners! The entire course is well structured and has good hands-on assignments. SQL is extremely essential for Database management and fun learning so please do try this one out!
The lessons were short and easy to follow, providing all the basics as well as a few more advanced topics, to get student quickly up-to-speed on databases and SQL and their application in D/S realm.

The course is good but sometimes the exercise texts are not very clear and some of the lessons are very straightforward, leaving many doubts. The course should have a larger series of exercises and an automatic correction system that facilitates the review of the exercises. In addition, it would be interesting to have a module on how to use IBMDB2 without the online platform, but through Jupyter on the computer.

Apart from errors in the open source tools for the hands on labs, this course is fantastic and well crafted to introduce Databases and SQL. the optional sections are useful for those without good grasp of knowledge about databases and their types. make sure to take them. The labs are good, but always there is connection problems. If they will fix this, it will be one of the best introduction courses out there.

Upon initiation the course does cater for people with no background with many exercises. Maybe a small introduction to python would do, just to teach the people abit on python because with assistance from youtube there are always different methods to approach the problems. Maybe a clarification of problem questions should considered. Some questions are really hard to understand what is actually asked for.

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.

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.

it is a very good course that I have learned a lot from, however, I got confused in too many situations when trying to run queries and complete assignments. I dont know why but instead of trying to type the proper query, the course pushed me in a way to find the proper query somewhere, copy it and that's it. A very positive point was the amazing support and quick responses from Rav.

Very good course as an intro to SQL. The materials is presented at a good rate and there are good lab exercises to practice what you learn. The final assignment really puts what you learned to the test. There is a section in week 3 about APIs that lost me and I had a hard time seeing connecting it to the rest of what was being taught, but otherwise a useful course.

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
By Stephanie O•
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.

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.
By Olavo S•
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.
By Sasanka B•
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
By Phyllis J•
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.
By Sridhar M•
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
By Jaime F•
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.
By Bhavesh S•
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.
By Andreas P•
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.
