Tutorial: Creating business logic

In this tutorial, you create the business logic for a new view, controller command, data bean, and entity bean. New business logic is required when a change is made to the default business logic behavior of WebSphere Commerce. This tutorial guides you through creating business logic to support an application to track bonus reward points earned by customers in a new customer loyalty program application. The assets you will create include a view, a controller command, a task command, data beans, and an entity bean. This tutorial is for demonstration purposes only and does not reflect all the logic required to build a fully functional loyalty program application. From this tutorial, you learn the common development steps for creating the previously listed code assets.
