Business Rules

To model Business Rules in Enterprise Architect, you work through the following steps:

• Create a Rule model to define business rules.
• Create a Business Domain model, which provides the business vocabulary for defining business rules.
• Create a Rule Flow model, which groups the rules for a specific task under a Rule Task, and provides the order in which the business rules are executed.
• Model the rules in the Rule Composer, which enables the rules to be transformed to a logical level of detail.
• Validate the rules in the Rule Composer.
• Generate code for the business rules using Enterprise Architect's general code generation methods.

These steps are represented graphically in the following flow:
