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 to propose a ``kernel'' system providing the ``essentials'' for distributed processing and to show the important role database technology may play in supporting such functionality. These include a powerful process management environment, created as a generalization of workflow ideas and incorporating transactional notions such as spheres of isolation, atomicity, and persistence and a transactional engine enforcing correctness based on the nested and multi-level models. It also includes a tool-kit providing externalized database functionality enabling physical database design over heterogeneous data repositories. The potential of the proposed platform is demonstrated by several concrete applications currently being developed.
