SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a concise reference for Ordo expression syntax, helping users write, read, and reason about rule conditions with accuracy and speed.

Core Features & Use Cases

  • Operator reference: covers comparison, logical, and arithmetic operators used in rule conditions.
  • Field access and literals: demonstrates dot notation, array indexing, and safe access patterns like coalesce.
  • Built-in functions overview: summarizes common functions for string manipulation, math, and type checks to shape data and decisions.

Quick Start

Use this quick reference to craft a condition such as age >= 18 and status == "active", then combine with a transformation like len(name) or upper(code) to produce outputs.

FAQPage Schema
How do I write rule conditions using Ordo expression syntax?

Ordo expression syntax lets you write rule conditions using comparison, logical, and arithmetic operators like age >= 18 and status == "active". You combine field access with built-in functions to ensure correct evaluation and data transformation.

What built-in functions are available for data transformation in Ordo rule conditions?

Ordo expression syntax provides built-in functions for string manipulation, math operations, and type checks. You can use functions like len(name) or upper(code) to shape data and produce transformation outputs within your rule conditions.

How does field access notation work in Ordo expressions?

Ordo expressions support dot notation for field access, array indexing for list elements, and safe access patterns like coalesce to handle null values. These notations ensure accurate data retrieval when evaluating complex business logic.

Can I combine conditional expressions with operators in the Ordo engine?

Yes, Ordo expression syntax allows you to combine conditional expressions with comparison, logical, and arithmetic operators. This lets you validate complex business logic by chaining multiple conditions and transformations together.

What is the best way to validate complex business logic using Ordo expressions?

The best way to validate complex business logic is to combine Ordo conditional expressions, field access notation, and built-in functions. This approach ensures correct evaluation and data transformation within the Ordo engine for software engineers and data specialists.

Why is my Ordo rule condition not evaluating correctly?

Incorrect evaluation often stems from improper operator usage, invalid field access notation, or unsupported built-in functions. Use this Ordo expression syntax reference to verify operator syntax, safe access patterns, and function parameters.
