Declarative Rules

Declarative Rules in PEGA

Declarative rules represent one of PEGA's most powerful features, allowing you to express business logic in a declarative manner rather than procedural code. These rules automatically execute when their dependencies change, providing reactive and maintainable business logic implementation.

Types of Declarative Rules

PEGA provides several types of declarative rules, each serving specific business logic needs.

Advanced Constraint Patterns

Sophisticated constraint implementations for complex business scenarios.

Expression Calculation Strategies

Advanced techniques for implementing complex calculations using declare expressions.

Trigger and OnChange Implementation

Advanced patterns for implementing reactive business logic.

Integration with Procedural Rules

Combining declarative and procedural approaches effectively.

Testing Declarative Rules

Comprehensive testing strategies for declarative logic.
