摘要
A method for updating a decentralized database, in particular a navigation database, that is subdivided into segments, by transmitting an updated segment from a central database subdivided into corresponding segments to the decentralized database, and by storing the updated segment in the decentralized database avoids inconsistencies in an only stepwise update in that the segments are modeled to a hierarchical model in the decentralized database, and in the updating of the segment the particular segments from which the segment depends are updated as well.
