A Business Rules Engine (BRE) is a software component that allows end users to add and modify business process management procedures without programming skills. The rules, based on data from a database, are executed as operations.
Business Rules Engines separate the execution code for business rules from the rest of the business process management( BPM). This allows end users to modify business rules without having to have programming skills. For these changes, users turn to low-code/no-code( LCNC) platforms and can change business processes without professional programmers and perform business analysis on their own. Once a change is made, the engine evaluates the impact on other rules in the system and flags the user when there is a conflict.
