Model-driven architecture

Model-Driven Architecture (MDA) is like a computer working out a math problem. The problem is like a map that shows what the computer needs to do, and the computer uses pieces like math equations to work out the answer. It looks at the problem and finds out what pieces it needs to use and in what order. This makes it easier for people to create and use software, because they can focus on just putting the pieces together instead of dealing with all the different parts of the software.
