If you haven't, you're in for a treat. With this book, you'll learn about SQL through a multisensory experience that engages your mind — rather than a text-heavy approach that puts you to sleep.You’re learning great things about organizing the information from multiple documents into categories of data and arranging them in a grid-like table. You may have worked with data like this in software for spreadsheets such as Excel or Google Sheets. In this book, we’ll use SQL to create tables as well as find the information we put in them. So what is SQL? SQL is a programming language for storing and retrieving tabular data, and by “tabular,” we just mean information that you can write down in a table with rows and columns. Even though it was introduced in the 1970s, SQL remains very popular in today’s workplace.
