This paper describes the experience of porting a 25,000 line distributed Java [GJS97] program to version 0.3.5.1 of the orthogonally persistent programming environment PJama. The ...
This paper argues that caching, atomicity and layering are fundamental to persistent systems, and that the transactional object cache architecture, as an embodiment of these conce...
Java is a popular, object oriented language that is runtime type safe. As such, it has been seen as an attractive basis for the implementation of orthogonally persistent systems b...
