SQL is like a computer language that helps you work with data in a database. It stands for Structured Query Language. When you use SQL you type commands that tell the database what data you want to find or use. An example of a command might look like this: SELECT name, address FROM customers WHERE city = ‘New York’; This command tells the database to find all the customers whose address is in New York City and show us their name and address. SQL is a powerful language that lets you find and store data in ways that would be very difficult to do without it.
