Abstract
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.
