Then, by taking into consideration a number of implementation issues ranging from architectural styles, nonfunctional quality criteria to be maximized (e.g., performance, adaptability) and target technology platforms, one or more platform-specific implementation models are derived from the design model. Many instances (denoted by the *) of Class2 can be associated with Class1. The arrows indicate whether, given one instance participating in a relationship, it is possible to determine the instances of the other class that are related to it.
