In a distribution network with having various points (2, 3, 4), such as a manufacturer (2), distributors (3) and points of sale (4), local databases (10) are provided at least at some of the points. When an article arrives at such a point, a record describing it is transferred from a central database (5) to the local database (10). When the article leaves the point, the record is transferred back to the central database (5). In other words, while the article is at a given point, the record remains available for access and modification at the local database (5), which obviates the need to consult the central database (10) each time the record is to be accessed.
