Distributed shared memory infrastructure for virtual enterprise in building and construction

This paper proposes a new approach to building a virtual enterprise (VE) so ftware infrastructure that offers persistence, concurrent access, coherence and security on a distributed datastore based on the distributed shared-me mory paradigm. The platform presented, persistent distributed store (PerDiS ), is demonstrated with test applications that show its suitability and ade quate performance for the building and construction domain. In particular, the successful adaptation of standard data access interface (SDAI) to PerDi S and a comparison with CORBA are presented as examples of the potential of the distributed shared-memory paradigm for the VE environment.
