GOODS is a distributed, language-neutral object database from Konstantin Knizhnik. It's available from http://www.garret.ru/~knizhnik/goods.html .
This client provides transparent storage of Smalltalk objects, or, given some extra type information, compatibility with the GOODS Java interface storage conventions, for easy sharing of object data between Squeak and Java.
See http://minnow.cc.gatech.edu/squeak/3492 for more information.
Requires GOODS 2.72 or later
The latest version of this package can be found on SqueakSource (http://squeaksource.com).
