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.

I wanted to learn a little bit of everything about SQL queries and I found exactly what I was looking for. The lessons were quick, packed with information and challenging. When I combine this knowledge with what I have already learned in Python I feel like I am well on my way to bigger projects.

Great introduction!

I had no experience with SQL at all. This course helped a lot in understanding many details about RDBMS.

I can now do many useful queries and have a head start when start to read a RDBMS book to deep my knowledge!

The course is pretty good and consists of step-by-step classes which learn us basic skills we are going to use and evolve in our real job: what is a query, how we can use and create it, how to obtain data from a database, how to check out some particular data from a database, and so on.

Many thanks for such interesting course!

The process is challenging (especially the final assignment). But I believe that you will gain sense of accomplishment when you figure all the questions out!
