Business Rules Engines (BRE) are software tools that allow businesses to manage and automate complex business rules and decisions. A BRE provides a centralized platform to define, validate, and execute rules based on specific criteria or conditions. With a BRE, businesses can quickly adapt to changes in business rules and regulations, improve operational efficiency, and reduce errors and risks associated with manual rule-making. BRE requires computer programming, database management, and knowledge of business rules and logic.
