Rule engine

A system that applies predefined rules to data to evaluate conditions, guide decision logic through a series of choices, and determine the correct action or response.

Example

An e-commerce platform might use a rule engine to determine the correct tax rate for each order. It evaluates the customer’s location, product category, and other relevant factors against a set of tax rules. The rule engine then calculates the applicable taxes, helping maintain compliance with regulations and keeping the checkout process clear for the customer.

On Decisimo's business rules engine, rule sets apply every matching if-then rule in order.
