課程概述

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....

The most serious and closest to professional course I've taken on Coursera so far (out of about 20). Both fundamentals and real-life practical skills are taught in a plain and clear manner. The Labs are great.

Great course! I learned the basics of SQL. Wish there was a more in depth discussion of SQL and its capabilities, but I received a great base and it helped me remember everything I had forgotten from college.

Good hands-on practice with SQL in a Python and Data Science context. Covers the very basics of SQL, including relational database fundamentals plus DDL, and then builds to some decent challenging queries.

It was a extremely challenging for a newbie to the world of SQL, there were areas in which some simple guidance from a professional would help. Overall I feel comfortable with what I was able to achieve.

An appropriate course for the beginner. Introduce the basic queries statement. And the most useful point is instructing how to use DB2 and how to start SQL in python. The DB2 is fluent and easy to use.
