Ok, so let's say you're the boss of a really big company with lots of people working for you. You need to know what's happening in your company so that you can make good decisions. But you can't ask every single person what they're doing every day because that would take too much time and they might not know how to tell you what's important.
That's where an executive information system comes in! It's like a special computer program that helps you see all the important information about what's happening in your company. It takes data from different parts of your company, like sales, production, and finance, and puts it together in a way that you can understand easily.
The executive information system shows you things like how much money your company is making, how many products you're selling, and how well your employees are doing their jobs. You can look at charts and graphs to see patterns over time, and you can even set it up to give you alerts if something important happens.
Basically, the executive information system helps you be a better boss by giving you all the information you need to make good decisions!
