Overview of Global : Communications Between Locations
Communications Between Locations
In Global, inter-location communication is handled by a program, separate from the base product known as the Global daemon, running at each location.
A daemon is a process that runs on a computer, usually as a background process, without the need for any direct user interaction, and provides a service to other processes. There are many programs that are provided by the operating system for managing access to file systems, printers etc. These programs are typically implemented as daemon processes.
If a communications link is lost, the software engineers at each location will be able to continue working uninterrupted with the current data at that location. When communications are restored, the updates will re-start and the location will be updated with the latest available data.
