课程概述

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.

Some instructions could have been more clear.

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

All on all, i am satisfied.

It would be great if things got covered in a more structured manner. Week 4 is so damn confusing and took a lot of precious time.

CRIME.CSV file had an incorrect setup (date format), since that part was not part of the learning I think it should be corrected

Lots of good material. Much of it is a commercial for IBM. Directions for operating within the IBM data structure is outdated.

Feels like lectures are being give by an AI instead of an actual teacher. Also some things get repeated in several videos.

Good course material - would suggest finding a more viable solution to grading assignments than peer-review.

Week 4 was a bit intense and I think the topics could have been decompressed over one more week.

Lots of hands on skills. Some mistakes in the Notebooks make some problems confusing, though.

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