The invention discloses a map data migration device and a method. The device comprises a display module, a migration determination module, a position acquisition module, a target determination module and a storage module. The display module is used for sub-screen displaying map interfaces of multiple map applications on a display screen of a mobile terminal; the migration determination module is used for determining the map applications to be migrated according to first touch operation received by the display screen, and delineating areas to be migrated in the map interfaces of the map applications to be migrated; the position acquisition module is used for acquiring edge geographic positions of the outer edges of the areas to be migrated in the map interfaces of the map applications to be migrated; the target determination module is used for determining the target map applications required to be migrated to the areas to be migrated according to second touch operation corresponding to migration commands when the migration commands are detected; the storage module is used for storing map data of the areas to be migrated into a storage space of the map data corresponding to geographic positions of the edges in the map interfaces of the target map applications. According to the map data migration device and the method provided by the invention, the waste of mobile terminal flow is reduced.

The invention relates to a digital book updating and distributing method and system. The method comprises the following steps of: amending an existing digital book by an author client; marking the amended content by a server to form an amended unit; selecting to download all of or a part of the amended part by a reader client; and combining the downloaded amended unit and a local digital book to form a new digital book. In the invention, the amended content is marked by the server to form the amended unit, so that the reader client can subsequently and quickly select to downloaded all of or a part of the amended unit to form the new digital book; and thus, the existing content in the local digital book of the reader client is prevented from being repeatedly downloaded, the network flow is effectively reduced, the bandwidth requirement is reduced, and the issue cost of a publisher and reading cost of a reader are reduced.
