Abstract
A horizontal fragment of a database class in an object-oriented database system contains subsets of its instance objects (or class extents) reflecting the way applications are accessing database objects. Allocating well-defined fragments of classes to distributed sites has the advantage of minimizing transmission costs of data to remote sites as well as minimizing retrieval time of data needed locally. A re-fragmentation of the system is needed when application access and schema information have undergone sufficient changes. We provide a technique for measuring the performance of object horizontal fragments placed at distributed sites. This work provides a platform for dynamic object horizontal fragmentation and for comparing object horizontal fragmentation schemes.
