OBJEKT: A Persistent Object Store with an Integrated Garbage Collector

Abstract

This paper describes OBJEKT, a single-level persistent storage system designed for the REKURSIV architecture. It will be shown that OBJEKT can be microcoded to implement “objects” efficiently, and that data integrity can be guaranteed by provision of an object oriented instruction set. Particular attention will be paid to its facilities for type and range checking, to its object by- object paging strategy and to ways of enhancing parallelism during garbage collection. © 1987, ACM.
