I need a persistent object store because my masters project is object oriented and I want to save the objects across sessions. I'm writing using PCL in Macintosh Allegro Common LISP under the MacOS (not AUX). From an earlier request to the Mac LISP group I received pointers to functions for saving objects to (and loading them from) files. However, it would be much better to have a persistent object store (or object oriented database). I need one which has these features (I'm new to the persistent object world so please forgive my needing to make them explicit): - load objects on call (no waiting for an entire file to load and better use of memory: not all objects must be loaded and some can be unloaded if memory gets tight). Ditto for saving. - distributed store (don't have to know the details of where objects are stored and you get transparent network access). - concurrent object access + security (can protect objects based on user) - fast saving, loading, and memory access The ideal solution would be a portable system written in LISP to support CLOS; another solution involves using an OODB which I can invoke via foreign function calls to C from LISP. Would anyone who knows of suitable systems (commercial or academic) please respond to me? Thank you. Matthew Cornell Knowledge Communication Systems Group
