Data definition language

Data definition language (DDL) is like a special language that people use to teach computers how to store and organize information.

Imagine you have a big toy chest with lots of different toys inside. You want to keep these toys in order so you can find them easily when you want to play with them. DDL is just like telling someone how to organize your toys, but instead of toys, it's data (information).

First, you need to decide what kind of toys you have. Are they dolls, cars, blocks, or something else? This is like choosing what kind of information you want to store in your database.

Next, you need to give each toy a name or a label. This is like giving each piece of information a specific field name, such as "first name" or "date of birth."

Then, you decide where each toy should go in the toy chest. Should the dolls go in one area and the cars in another? This is like deciding how your data should be arranged and organized in your database.

Finally, you need to make sure that everything is set up correctly and that the toys (or data) are all in the right place. This is like checking and testing your database to make sure it works and that you can easily find and use the information you need.

So, in short, DDL is a special language used to tell computers how to organize and store information in a database, just like how you use labels and categories to keep your toys organized in a toy chest.
