A system, method, and computer program product are provided for handling bulk initial downloads of databases to mobile devices. Rather than straining the resources of a mobile device to recreate the database locally, a server can construct the database to the mobile device's requirements at the server by impersonating the mobile device. The server can then send the database, compressed and over an encrypted session, to the mobile device. The mobile device can then decrypt and uncompress the pages received, and then encrypt them using a local key for secure storage on a local storage device.

Bulk initial download of mobile databases

A system, method, and computer program product are provided for executing a notification query derived from a download cursor for a business object to identify an updated subscription. The download cursor is run against the updated subscription to generate result rows. The result rows are sent to a client device in an import message. Additional systems, methods, and computer program products are provided for guaranteeing at-least-once delivery of a message.

Message based synchronization for mobile business objects

A system, method, and computer program product are provided for invoking an operation to change a current data row of a table in a local database. As a result, a pending change data row is inserted in the table, distinguished by a primary key comprising a common key value and a pending change indicator. The pending change is then submitted for synchronization.
