In the real world, there exist taxonomic and non-taxonomic associations between objects. Taxonomic associatoins can be repesented by generalization and specialization which most current object- oriented languages support through inheritance. However, service for non-taxonomic associations is rarely seen. In order to maintain all of the goals of object-oriented programming, the non-taxonomic operations must be managed by the system in a uniform way, instead of being handled freely by different applications. This research proposes two simple but useful mechanisms, non-taxonomic link and non-taxonomic inheritance, for handling non-taxonomic operations between objects. The association is declared in the class object only once and all its instances can be served through simple inheritance.
