Chapter 2. New features

For complex DMN models, you can now use the DMN designer in Business Central to design multiple DMN decision requirements diagrams (DRDs) that represent parts of the overall decision requirements graph (DRG) for a DMN decision model. This improvement enables you to better organize DMN decision models with many decision requirements by dividing the model into smaller nested DRDs.

For more information about creating DMN models with multiple diagrams, see Designing a decision service using DMN models.

The traits functionality and its specific implementation code is moved to an individual module named drools-traits. To use traits, you can import the drools-traits module to Maven. The existing implementation is not supported in the executable rule model.

A new module named drools-metric is added, which can assist in the performance analysis of the decision engine.

For more information, see Designing a decision service using DRL rules.

You can follow the example in Creating a school timetable using Red Hat Business Optimizer with Spring Boot to create a school timetable.

For more information, see Creating Red Hat Decision Manager business applications with Spring Boot.
