репликация базы данных(The process of creating two or more special copies (replicas) of an Access database. Replicas can be synchronized, changes made to data in one replica, or design changes made in the Design Master, are sent to other replicas)
The process of creating and managing duplicate versions of a database(Replication not only copies a database but also synchronizes a set of replicas so that changes made to one replica are reflected in all of the others. The beauty of replication is that it enables many users to work with their own local copy of a database, but have the database updated as if they were working on a single centralized database. For database applications in which, geographically users are distributed widely, replication is often the most efficient method of database access)
