ELI5: Explain Like I'm 5

Database design

Database design is like organizing your room. When you organize your room, you decide where things should go making it easier to find things. Database design is the same idea, but instead of organizing your stuff, you're organizing data.

So let's say you have a lot of books, video games, and movies in your room. You may decide to organize them in different areas of the room - books on the bookshelf, video games on the desk, and movies on the TV stand. This is just like when designing a database - you have data, like names, addresses, products, and you have to decide where to store that information. You can create different tables or areas of the database for each kind of data, like the bookshelf for the names, the desk for the addresses, and the TV stand for the products.

Whenever you want to find something in your room, you know where to look. It's the same with databases - when you need to find something, you know what table to look in and it will be easy to find. That's database design!
