SQL is the world's most widely used programming language for database management, an essential skill for back-end web development and data analytics. Designed for beginners, this Introduction to SQL course will give you the foundation you need to get started with Structured Query Language in Microsoft SQL Server, through hands-on application and examples.

By the end of the course you will have a practical understanding of how to set up and connect to a server, create databases and tables, insert and update data, and create and filter queries to get the valuable insights you need.

In this course we are using Microsoft SQL Server's T-SQL, but you will be able to apply most of what you learn to many other databases such as MySQL, PostgreSQL, Oracle and more.
