Implementing Persistence for an Object Oriented Language
J. Eliot B. Moss · 1987
RECENTLY WE HAVE BEEN INTERFACING AND INTEGRATING AN OBJECT SERVER (OB SERVER, DESIGNED AND BUILT BY PROFESSOR STAN ZDONIK AND HIS GROUP AT BROWN UNIVERSITY [SKARRA, ET AL 86]) WITH AN OBJECT ORIENTED LANGUAGE (TRELLIS/OWL, UNDER DEVELOPMENT IN THE OBJECT BASED SYSTEMS GROUP AT DIGITAL EQUIPMENT CORPORATION [SCHAFFERT, ET AL 85, SCHAFFERT, ET AL 85, O''BRIEN 85]). THE GOALS ARE TO SUPPORT REASONABLY TRANSPARENT PERSISTENCE IN A MANNER CONSISTENT WITH OWL AND ITS HEAP-ORIENTED, TYPE-CHECKED, MULTIPLE INHERITANCE SEMANTICS, AND TO EXPLORE MEANS FOR THE PROGRAMMER TO EXPRESS DESIRED CLUSTERING OF OBJECTS TO IMPROVE PERFORMANCE. WE DESCRIBE OUR DESIGN AND RESULTS TO DATE.
