Decision support system
A decision support system is like a computer program that helps people make nice decisions. It takes in a bunch of data and information, looks at what the experts know about a situation, and then tells the person using it which choice is the best one to make. It's like having a really smart friend that knows a lot about the things you're trying to decide, and can help make the best choice.
