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.

This has many hand-on assignments, which helps understand a lot. No doubt this is the best course for SQL beginners ever

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.

The lectures could be quite challenging to understand due to the technical jargons used.

Course was great but RDBS in browser was so slow that i need to wait for couple of minutes to create a table. Thankfully, doing the same in python took few seconds

Tough start, really boring material and I hoped I never needed to work with SQL. Later though it started to click a bit better and was (slightly) more enjoyable.
