Abstract:
The invention relates to a method for managing a database shared by a group of applications. The database comprises elements, each comprising a value and a version number. Each application comprises a replica of the database.
The method comprises a step for modifying the value of an element in the replica of an application, called active application, a step for incrementing the version number of said element in said replica of the active application, a step for transmitting, via the active application, transmission data to the other applications, the transmission data comprising the modified element, and an earlier version number of this modified element, a synchronization step, during which at least one application other than the active application updates its replica based on a comparison of the earlier version number with that of said element in this replica.
