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.

Great course. All what you need to understand DB concept (if you are new there) + real life data analysis with Python. Very useful.

Highly recommended. I was a newbie for mySQL and this course offers a good entry point and insights for database and SQL. The final assignment could be somehow challenging for people without programming experience, but the discussion forum is active and the course instructor Rav is very attentive, responding to questions in the forum. I solved some problems just base on the search funtion in the forum. This is the best course I learned with coursera so far!

I liked this course. I knew SQL already so it was pretty easy. But the tools and how to use them was new and well presented and organized.

Week 3 onwards the course is quite good.

First two weeks are basic SQL which you can skim through.

I like the practice in this class. Playing with real data is so interesting.

SQL language is not so complicated itself and with enough practice I feel that I understand how to combine several queries in proper order.

I had never worked in SQL, so this course definitely provided me a good grounding on database handling. I do not have too much experience with pandas library of python, and this course provided me some hints on deepening my understanding in pandas, and the logical connection between pandas and SQL. It was also good to see the techniques which can be applied in Jupyter notebook or in python code itself to use SQL commands.
