We all use databases to store our data around our applications, storing user settings and data received from client. If you ever had to create a category parent/child relationship in a e-commerce store for instance, this is a very good article explaining both ways and explaining the whole idea and schema of this wonderful way of easily managing a nice tree of categories that you may need for your posts, real-estate properties, products, groups, and so on.
