Global Working
Global allows DBs to be spread across different locations. Global propagates changes from one location to another. The Global daemon does the propagation.
With global, there may be copies of a database or extract at multiple locations, but only one copy may be writeable. A database is said to be primary at a given location if it is writeable there, and secondary if it is not. A DB may be made primary at any location.
Different extracts from the same extract family may be primary at different locations. This allows multiple different locations to modify the same DB.
