- I can't point you to any texts, however I can give you some of
- my experiences. I recently worked on a project to provide a command
- and control system to the U.S. Army. Part of the project involved a
- X-windows based system hosted on Sun workstations. The original designers
- of the system decided to use properties as a method of communications
- between two applications that would need to be run, possibly, on physically
- separate workstations. The use of the properties made it very easy to
- establish communications between the two programs. Given that they were
- only exchanging small text strings of information, the probable added
- overhead of using this form of transfer was negligible and worked out
- very well. One interesting aspect of properties is that you can actually
- think of them as "Shared Global Memory", even though the properties exist
- on different systems. Thus some sort of synchronization method is needed
- when accessing the properties.
