Pertemuan:9 (Object Modelling : Advance Relationship)
In this section, the discusion is about :Advanced Concepts on:
-Dependency
-Generalization
-Association
-Realization
Eight Stereotypes of Dependency Among Classes; bind: the source instantiates the target template using the given actual parameters, derive: the source may be computed from the target, friend: the source is given special visibility into the target, instanceOf: the source object is an instance of the target classifier, instantiate: the source creates instances of the target, powertype: the target is a powertype of the source; a powertype is a classifier whose objects are all the children of a given paren, refine: the source is at a finer degree of abstraction than the target, use: the semantics of the source element depends on the semantics of the public part of the target
Generalization-One stereotype – implementation: the child inherits the implementation of the parent but does not make public nor support its interfaces
Association-Four Basic Adornments of Association: name, role, multiplicity, & aggregation.
Realization-A realization is a semantic relationship between classifiers in which one classifier specifies a contract that another classifier guarantees to carry out. Realization is sufficiently different from dependency, generalization, and association relationships that it is treated as a separate kind of relationship. Semantically, realization is somewhat of a cross between dependency and generalization, and its notation is a combination of the notation for dependency and generalization.
