Model Business Rules

1

In the generated Business Rule Model, expand the Business Rule Package and double-click on the Business Rule diagram to open it. The diagram shows two example Business Rule elements connected to an example Rule Task.

In the Diagram Toolbox, the 'Rule Model' pages display.

2

If you should need to create another (empty) Business Rules diagram, right-click on the Business Rules Package and select 'Add Diagram'.

On the 'New Diagram' dialog, type an appropriate name in the 'Diagram' field, click on the 'Select From' header and select the 'Project Management > Complete' Perspective group, and then scroll down and select the Business Rule Model Perspective from the panel beneath the header.

Select 'Rule Model' in the 'Diagram Types' panel and click on the OK button.

3

For each business rule you want to identify, drag the 'Business Rule' icon from the Toolbox.

Type the rule (or a shortened version of it) in the 'Short Description' field of the element 'Properties' dialog. This displays as the name of the element in the diagram.

You will later define the parameters of the rules using the Rule Composer.

4

When you have created all the required Business Rule elements, create the Business Domain model, the Rule Flow Activity diagram and the Business Task elements.

Use the Business Rules diagram

Open the Business Rules diagram and drag onto it a Rule Task element from the RuleFlow Activity in the Browser window.

Create a Dependency relationship to the Rule Task from each Business Rule element that applies to it (by dragging the connector from the Toolbox, or by using the Quick Linker arrow on the Business Rule element).

Repeat the process for the next Rule Task element from the Rule Flow Activity.

Create any additional Business Rule and Rule Task elements that are necessary (this should not be a common event); you must add any new Rule Tasks to the Rule Flow Activity diagram.

Save the diagram and open the Rule Composer for the first Rule Task element.

Assemble existing elements through the Rule Composer

In the Browser window, open the Rule Composer on a Rule Task element, and drag each applicable Business Rule element from the Browser window into an empty row of the Rule Statements table.

This establishes a Dependency relationship between the Rule Task element and each Business Rule element.

Continue to compose the rule conditions.

Use the Relationship Matrix

You can quickly create all the Dependency relationships between a number of Rule Task elements in the Business Domain Model Package and the Business Rule elements that apply to each one.

Set the source element 'Type' to 'BusinessRule' and the target element 'Type' to 'RuleTask'.

Set 'Link Type' to 'Dependency', and 'Direction' to 'Source->Target'.

Set the 'Source Package' to 'Business Rules' and the 'Target' to 'Business Domain Model'.

In the cell at each intersection of a Business Task column and the appropriate Business Rule row, right-click and select the 'Create new relationship | UML:: Dependency' option.

When you have finished creating the relationships, close the Relationship Matrix.

Open the Rule Composer for the first Rule Task element in the Browser window.
