Why Learn SQL?
We live in a data-driven world: people search through data to find insights to inform strategy, marketing, operations, and a plethora of other categories. There are a ton of businesses that use large, relational databases, which makes a basic understanding of SQL a great employable skill not only for data scientists, but for almost everyone.
In this course, you’ll learn how to communicate with relational databases through SQL. You’ll learn—and practice with 4 projects—how to manipulate data and build queries that communicate with more than one table.
