Object exchange service for an object-oriented database system

Abstract

An object exchange service (OXS) and an external object representation (EXTOR) are described in the context of a distributed object-oriented database. EXTOR is the common representation that facilitates the sharing of information among a network of machines. The aim is to represent complex structured information in an efficient external form and to provide maximal sharing of information among computing sessions. OXS is a service which, together with the concepts of object boundary, global objects, and object closure, provides the exchange of information using EXTOR. A brief description is provided of the distributed object-oriented system that utilizes this service, the performance results for OXS, and the future directions for the design of generalized object exchange services in heterogeneous computing environments.<>
