What term describes the state domain of a business object in Avaloq?

The term that describes the state domain of a business object in Avaloq is indeed "Fields." Fields represent the attributes or properties of a business object that hold data. In the context of Avaloq, these fields define the characteristics and the current state of the object, essentially capturing the information that pertains to that specific business entity. For example, in a banking application, the fields of an account object may include attributes like account number, balance, and account holder name.

In contrast, methods are functions or procedures that belong to a business object and define behaviors, while instances refer to specific occurrences of a business object created based on its definition. Parameters are values that are passed to methods to guide their behavior, but they do not describe the state of a business object itself. Therefore, "Fields" is the appropriate term to identify the state domain, as they directly relate to the data structure that encapsulates the information contained within the business object.
