Defining interfaces
You can add the following objects to an interface:
Object
Attribute
Operation
Business rule
Description
Named property of an interface that defines the characteristics of an interface
Implementation of a service that can be requested from any object of the interface in order to affect behavior
Written statement specifying what the information system must do or how it must be structured to support business needs
You add an object to an interface from the list in the page corresponding to the object, in the interface property sheet.
When you add an object to an interface in this way, you in fact create a copy of the object. The new object exists as a unique object, and you can then make changes to it as you would to any object in the model.
Adding an attribute to an interface
An attribute is a named property of an object that defines the characteristics of the object.
You can add attributes to an interface that already exist in the model and which belong to other objects.
