Natural key
Okay, kiddo! Let's talk about natural keys. So, we often store lots of information in our computer systems, like our names, addresses, phone numbers, and other data. Sometimes, we need to label this information with something called a "key." Think of it like a name tag that helps us keep track of all the different pieces of information.
A natural key is a special kind of key that uses natural characteristics of the data to create the key. For example, let's say we're storing information about different animals like their color, size, and kind. We could use the combination of these characteristics to create a natural key.
It's like when we make a list of our favorite things, and we use specific details to help us remember what we wrote down. If I wrote "pink popsicle," I would remember that it was my favorite flavor and color because of the words I used.
Using natural keys can be helpful because they're unique to the information we're storing. We can easily search and sort the data based on these keys to find what we need quickly.
So, that's the basics of natural keys, my little friend! Pretty neat, huh?
