<p>A device for managing data relating to entities which may or may not be known beforehand comprises a central processing unit which, supplied with a suitable program code, is capable of receiving and storing the data in the form of status messages relating to one or more entities. The data is stored in a dynamic structure which for each entity provides space for a unique identification and for a first collection of references to possible subordinate entities and a second collection of references to superior entities. The structure is herein set up such that a status message relating to any entity is likewise valid for each subordinate entity associated with the relevant entity by means of its first collection. <IMAGE></p> |
