An information system, in simple terms, is like the brain of an organization. It's a system that collects, organizes, stores, and distributes information to help in decision-making, coordination, control, analysis, and visualization within an organization. Think of it as a library, where books (data) are collected, categorized, stored, and lent out to readers who need them. But unlike a library, an information system also processes and analyzes the data to create meaningful insights, just like our brain processes information to help us make decisions.
