Treffer: WEA, A Distributed Object Manager based on a Workspace hierarchy

WEA is our implementation of a new architectural model for virtual memory access, the WorkSpace. It relies on a generalisation of client / server model and enables to build new distributed applications. The workspace supplies uniform access to a distributed persistent object store. This paper describes several ways of building multi-workspace architecture, and an implementation of this architecture. This implementation is based on new operating systems features.

However, the developer usually has to use file systems for data archival. File systems do not enable a simple memorization of pointers on the archive, or direct management of objects in the archive. Persistent Object Managers enable full and reliable integration of the functionalities of objectoriented programming languages, and .
