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.

One of the best course I completed on Coursera. All the learning material is well organised and easy to understand. Also the non-graded sections regarding relational databases are interesting.

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.
