What is Rules Engine?

A rules engine is a software system that executes rules. These rules are typically conditional statements that define actions to be taken based on certain conditions. Rules engines are commonly used to automate decision-making processes, business policies, and expert systems. They allow for the separation of business logic from the application code, making it easier to modify and maintain the logic without changing the core application. They are often used in areas such as fraud detection, loan processing, and pricing.
