Chapter 1. Databases and Tables: Organizing your Information

Image

It’s time to bring order to your data. These days, just about every aspect of life involves data: the applications on your phone, the appearance of your social media feed, and even those detailed notes you take about your flossing habits. But all that information can only be useful if it’s arranged in a meaningful way so you can find what you want, when you want it.

You need a system to help you store and organize your data, and you need it now. Tables allow you to establish law and order and to craft your bits of info into rich assets, ready to be mined for insights. So turn the page, come on in, and get ready to enjoy the orderly world of relational databases.
