Class diagrams are typically used, although not all at once, to: Explore domain concepts in the form of a domain model; Analyze requirements in … Despite this convention, users of UML may stipulate a sense of dependency suitable for their domain, which makes a more abstract element dependent on that which is more specific. Domain classes would be all the things that are implementation independent User Item Delivery Address Delivery Date Payment In the design class we'd need to be more specific to the implementation of the language. Permission is a kind of dependency. Class diagram pros/cons • Class diagrams are great for: – discovering related data and attributes – getting a quick picture of the important entities in a system – seeing whether you have too few/many classes – seeing whether the relationships between objects are too complex, too many in … The obligations that may be associated with an interface are in the form of various kinds of constraints (such as pre- and postconditions) or protocol specifications, which may impose ordering restrictions on interactions through the interface.
