The model class contains getter and setter methods for each of the parameters defined in an advanced rule, while the service class contains the operation to be performed with the model.
The model name as well as the service name are determined by the property SDK Class Name specified when modeling the advanced rule.
For example, if the "taxCalculation" advanced rule is used when downloading the Java sources of the rule, you get a taxCalculation.java file that represents the model and another taxCalculationService.java file with the available operation of the service.
