    摘要: A method and system for synchronizing a main database of a server and a local database of a handheld device. A user can use an application residing in the handheld device to make transactions in the local database. In a synchronization operation, a synchronization client is used to: establish a connection between a server and the synchronization client; receive an identifier for the main database's structure from the server; receive an identifier for the version of the handheld application from the server; send transaction information to the server; receive metadata to update the handheld application; and receive data extracted from the main database from the server. The synchronization client is also used to update filter information used by the server to reduce the size of the data downloaded to the handheld device.

    摘要: A method and system for synchronizing a main database of a server and a local database of a handheld device. A user can use an application residing in the handheld device to make transactions in the local database. During a synchronization operation, the handheld device and server are coupled. The system then determines whether the application should be updated and, if so, causes the server to provide an update. The system also causes the handheld device to provide to the server information related to the transactions made by the user to the local database. The system causes the server to perform transactions on the main database based on the transaction information. The system also causes the server to extract data from the main database. The server can then provide at least some of the extracted data to the handheld device to update the local database.
