ImplementingCORBA Persistent Service 3

Abstract:  Abstract. The CORBA specification proposes a collection of Object Services that CORBA objects may use to enhance their functionality. In this paper, the authors share their experience gathered during the design and implementation of the Persistent Service as a part of the TOCOOS project. Moreover, the paper discusses benefits and drawbacks of reusing other Object Services, particularly Replication and Externalization, to support the Persistent Service. As the inter-dependencies among the three Object Services are rather complex and potentially circular, the paper aims at providing the reader with an analysis resulting in a set of guidelines a designer or a user of these services can benefit from when resolving inherent trade-offs.
