the OO7J benchmark.
I just published a very interesting resource in ODBMS.ORG, the dissertation of Pieter van Zyl, from the University of Pretoria.
The title of the dissertation is: “Performance investigation into selected object persistence stores” and presents the OO7J benchmark.
OO7J is a Java version of the original OO7 benchmark (written in C++) from Mike Carey, David DeWitt and Jeff Naughton = Univ
Wisconsin-Madison. The original benchmark tested ODBMS performance.
OO7J also includes benchmarking ORM Tools. Currently there are implementations for Hibernate on PostgreSQL and MySQL, db4o and Versant.
