Sobre o curso

Much of the world's data resides in databases. SQL (or Structured Query Language) is a powerful language which is used for communicating with and extracting data from databases. A working knowledge of databases and SQL is a must if you want to become a data scientist. The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment. The emphasis in this course is on hands-on and practical learning . As such, you will work with real databases, real data science tools, and real-world datasets. You will create a database instance in the cloud. Through a series of hands-on labs you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python. No prior knowledge of databases, SQL, Python, or programming is required. Anyone can audit this course at no-charge. If you choose to take this course and earn the Coursera course certificate, you can also earn an IBM digital badge upon successful completion of the course. LIMITED TIME OFFER: Subscription is only $39 USD per month for access to graded materials and a certificate....

Practice lab assignments were excellent in reinforcing my learning, they were just the right kind of challenging. This course has been the best one in the Data Science Professional series by far.

Clear, thorough, well-designed. Labs give useful practice, assignments and quizzes test the actual instructional content. This course is by far the best in the IBM Data Science specialization.

The course is really good for the beginners who want to learn SQL.

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,

Un bon cours concernant l'usage du SQL. Il reste nécessaire de s'appuyer sur des ressources extérieurs pour appréhender au mieux le langage.

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.

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.

I found week 3 a bit confusing, but otherwise it is a very useful and well explained course!

I found, sometimes, hard to use DB2

warehouse, so i prefered using other types os database.

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 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.

Some instructions could have been more clear.

Overall communication could be done better (if it's needed).

All on all, i am satisfied.

Good method of teaching and easy to understand content and language.

More Practice labs would be appreciate.

Would highly recommend the course, online learning material very good. Had connections issues with SQL server. Techy background helps. Be prepared to be patient and tackle technical connection and speed issues when running SQL queries. No course documentation warns you of the potential problems and the time estimates to complete the weekly module/tasks need to ignored. Monitor support weak as can be seen by the non-responses to questions in the forums.

A lot of videos that talk at you.

The content is clear and useful, but the videos are not attractive, so it is hard to pay attention.

Well explained, but both the quizes and the final project were too easy.

I wanted to like this course more, but wow was it dry. There were a lot of small nuisances with having so many logins to access course material that made things frustrating at times. Although, the point is to get you accustomed to an IBM centric workflow, that when you start to learn it, its not bad. I did enjoy the final project, and found it to be the redeeming quality of this course.

Some quizzes include questions about materials not yet introduced. The material could be much more interesting with more interesting and interactive examples. Hands-on Labs should include new materials rather than letting the students rewrite given queries in sql.

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

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.
