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....

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!

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 Directions for operating within the IBM data structure is outdated.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.

The first course I have encountered with lots of labs that make you research and engage more with the course material.

For non-programmers or people with no computer background, it is a bit difficult to comprehend. But overall it is OK.

La herramienta de trabajo de DB2 es lenta y poco amigable.

No me sentí cómodo usando las consultas en Jupyter

Cognitive labs is a good platform, but it is very unstable, making progress in the course longer and slower.
