Andrew File System
Supports information sharing on a large scale (thousands of workstations).
Uses a session semantics.
The entire file is copied to the local machine (Venus) from the server (Vice) when open. If the file is changed - it is copied to the server when closed.
- The method works because in practice most files are
changed by one person only (non-database).
- Measurements show that only 0.4% of changed files
were updated by more than one user during one week.
