Flyway is a tool that helps computers that store data keep track of changes in the way that data is organized. Imagine you have a toy box with a bunch of toys in it. Over time, you might add new toys or take some out. Flyway helps your computer keep track of these changes in a way that makes it easy for the computer to find the right toy when you want to play with it again. This is important because if the computer doesn't know where a toy is, it might not be able to find it and the game you want to play might not work the way you want it to. So, Flyway helps keep things organized and running smoothly.
