Abstract
The invention relates to a method of managing a database. The database includes a central database (3) and separate partially replicated databases (23-a, 23-b, 23-c). Each partially replicated database resides on a separate node (21-a, 21-b, 21-c). Each replicated database has an associated visibility strength. The method of managing a database determines the visibility strength of a partially replicated database to data being propagated, determines therefrom the visibility of the partially replicated database to the data being propagated, and propagates the data to a partially replicated database only if the node of the partially replicated database has visibility to the data.
