ABSTRACT	Many object based systems exist that support some form of distribution. Optimal application performance on distributed object based systems demands accurate class fragmentation and the subsequent allocation of these fragments to distributed sites. Vertical fragmentation must minimize application execution time by splitting a class so that all class attributes and methods frequently accessed together are grouped together into a single fragment. This paper describes a fragmentation algorithm that statically creates a set of fragments for the most complex object model: namely, one that supports inheritance and includes a part--of hierarchy, and whose method invocation structure is based on a nested transaction model. Our approach consists of grouping into a fragment, all attributes and methods of the class frequently accessed together by applications running on either this class, its descendant classes, its containing classes or its complex method classes. This research was partially su...	user correction - Legacy Corrections
