Quick reference
What is a database?
Welcome to the course! Let's learn about SQL and Databases!
When to use
Databases are used constantly throughout our modern lives.
Instructions
Databases are made of tables, which are made of columns and rows of data. Databases are used to store, manage, and update your data in an easily accessible way.
In today's data-driven world, there is not much of our modern lives that isn't run by databases. Every time you post to Facebook, Twitter and Instagram, that data is all stored in a database somewhere.
There are hundreds of types of databases, but once you know one - you can muddle your way through many of them. In this course we are using Microsoft SQL Server, but you will be able to apply what you learn to many other databases.
