Imagine buying a new computer. You bring home the box, full of excitement. You open the box—and it’s empty! You have a box, but it’s not much use, is it? Databases are exactly the same. If you have a database without tables, it serves no purpose. Tables are the data containers. Everything you might want to store in a database—customer information, order details, your comic collection—has to go into a table. Virtually everything you build in your database will rely on data from tables.
