Rule-Based Engines

A rule-based engine is a computer system that makes decisions by applying a set of predefined rules to given data. Think of it as a logical decision-maker that follows specific "if-then" instructions. For example, if a customer's purchase exceeds a certain amount, then offer a discount. These engines are used in various applications, such as fraud detection or customer support, where consistent, rule-driven responses are needed. They operate transparently, allowing users to understand how decisions are made based on the rules programmed into them.
