# Decision Modeling

> Guide to Decision Model and Notation (DMN) with Aletyx - from building your first decision model and using accelerators to advanced modeling, deployment, and best practices.

Welcome to our comprehensive guide on Decision Model and Notation (DMN). This documentation is designed to take you from the basics of decision modeling to advanced deployment scenarios, providing both theoretical knowledge and practical examples.

## What is DMN?

Decision Model and Notation (DMN) is a standard approach for describing and modeling repeatable decisions within your organization. DMN provides business analysts and technical developers with a common notation that is readily understandable to both audiences.

With DMN, you can:

* Create visual models of your business decisions
* Define precise decision logic using business-friendly notations
* Test and validate your decisions with real data
* Deploy your decisions as executable services

## Getting Started

If you're new to DMN, we recommend following these guides in order:

1. [Introduction to DMN](/docs/guides/tutorials/dmn/dmn-intro) - Understand the basic concepts and elements of DMN
2. [Your First DMN Model](/docs/guides/tutorials/dmn/dmn-basic-example) - Build a simple vacation days calculation model
3. [Working with DMN Accelerators](/docs/guides/tutorials/dmn/dmn-accelerators) - Use templates to accelerate your development
4. [Basic Deployment Options](/docs/guides/tutorials/dmn/dmn-basic-deployment) - Deploy your first DMN service

## Advanced Topics

Once you're familiar with the basics, explore these more advanced topics:

1. [Advanced DMN Modeling](/docs/guides/tutorials/dmn/dmn-deeper) - Complex decision tables, BKMs, and context expressions
2. [Advanced Deployment Options](/docs/guides/tutorials/dmn/dmn-advanced-deployment) - Cloud-native deployment patterns and scaling
3. [DMN Best Practices](https://docs.aletyx.ai/guides/tutorials/dmn/guides/tutorials/dmn/dmn-best-practices.md) - Guidelines for creating maintainable, efficient decision models

## Examples

Learn by example with these practical DMN models:

1. [Vacation Days Calculation](https://docs.aletyx.ai/guides/tutorials/dmn/guides/tutorials/dmn/vacation-days-example.md) - Calculate employee vacation entitlement
2. [Travel Insurance Pricing](https://docs.aletyx.ai/guides/tutorials/dmn/guides/tutorials/dmn/travel-insurance-example.md) - Price travel insurance based on risk factors
