Object-Orientation FAQ

Penguin (Stanford)

Penguin is an object-oriented interface to relational databases.
Penguin has its own simple language-independent object model with
inheritance for composite objects defined as views (called
view-objects) of a relational database.  These view-objects represent
data according to application requirements in such a way that multiple
applications can share overlapping, but different, sets of data.
Multiple applications may share data by having overlapping schemata
with differing composite objects and differing inheritance mappings.
We have a C++ binding, which supports multiple inheritance.  The
result is a framework for collaboration among multiple users, each
with differing perspectives about the system and its data.

Quote:
Franz, based in Berkeley, Calif., is now shipping AllegroStore, which the
company calls the first object database system designed for object-oriented
Lisp.
[...] The database is based on the ObjectStore engine from Object Design, also
in Burlington.  It supports multiple clients and servers, [...]
