This paper aims at classifying and discussing the various ways along which the \object" paradigm is used for concurrent systems.We distinguish the library approach, the integrative approach and the reective approach.The library approach applies object-oriented concepts, as they are, to structure concurrent systems through libraries.The integrative approach consists in merging concepts such as object and activity, message passing and transaction.The reective approach closely integrates protocol libraries and objectoriented languages.We discuss and illustrate each of these approaches and point out their complementary levels and goals.We will also make a careful distinction between the notions of concurrency on the one hand -referring to the non-sequential semantics of a program -and parallelism and distribution on the other hand -referring to the actual implementation of a concurrent system.
