Rule conditions and data transforms use Ordo expression syntax to evaluate logic via built-in operators, field access, and type conversions. You can define comparisons like age >= 18 and compute derived values directly within decision tables or rulesets.

Expression evaluation supports a comprehensive set of built-in operators for comparisons, logic, and arithmetic, alongside functions for string, number, and array literals. These allow you to succinctly express complex conditions and calculations.

Yes, rule expressions support safe field access using dot notation, array indexing, and coalesce operations for complex data structures. This prevents evaluation errors when navigating nested objects during runtime logic.

Yes, the expression engine includes safe type conversions to ensure rule conditions evaluate correctly across different data formats. You can parse and convert string, number, and array literals directly within your expression statements.

Use expression evaluation in rule-driven logic when you need to author, test, or runtime-evaluate conditions, calculations, and data transforms. It applies across authoring and execution contexts to validate rulesets and decision tables.

Ordo expressions may fail if array indexing or dot notation is improperly applied to complex data structures. Use safe access and coalesce functions to handle missing fields, and verify that literals and operators match the expected data types.
