This paper describes the architecture of OPERA, a generic platform for building distributed systems over stand alone applications. The main contribution of this research effort. is t,o propose a “kernel” system providing the “essentials” for distributed processing and to show the important role database technology may play in supporting such functionality.(More)
In this paper we address the problem of schema evolution in object-oriented database systems. Most currently available database prototypes either completely lack schema evolution facilities, or ooer a restricted set of special purpose schema evolution operators supporting simple schema changes. Our approach is diierent. We consider schema objects as objects(More)
