ObjectStore is a commercial object database for C++ and Java. The project was originally founded in 1988 by several former Symbolics employees, including Daniel Weinreb. It was inspired by the Statice database originally developed at Symbolics. The following are object database systems written in Lisp, based on the standard Common Lisp Object System:
