What does a business object in the ABAP RAP model define?

In the ABAP RAP (Rapid Application Programming) model, a business object represents a specific entity or concept within the application domain, such as a travel agency or a customer. It serves as a fundamental building block for implementing business logic and user interfaces. By defining a business object, developers can encapsulate the data and behavior associated with that entity, making it easier to manage and utilize in both transactional and analytical applications.

This means that a business object includes attributes (data) that pertain to the entity, as well as the methods (behavior) that define what can be done with that data. It encapsulates the core aspects of how a business entity is represented in the application.

Other options refer to different concepts within the ABAP programming model. For instance, behavior definitions are more focused on the actions that can be performed on the business objects, while CDS views are used for defining data models in a way that can be consumed by other components. Therefore, while those options are relevant to the overall structure of an ABAP application, they do not represent the primary purpose of a business object itself, which is to define the entity that encapsulates both data and behavior in the context of ABAP RAP.
