Abstract: An enterprise system which facilitates synchronization of offline data. Offline data created during an offline session or sessions (collectively an offline session) prior to synchronization is assigned a temporary key. Changes of offline data created during an offline session is assigned the temporary key of the data to which the change is associated. The temporary key is mapped to a new created backend key and stored in a mapping table. Using the mapping table, temporary keys associated with the changes are swapped with backend keys which the temporary keys are mapped. This maintains data persistency of newly created and change data during an offline session.

Abstract: A method includes providing a cloud-side database storing data, an objects model of the data, and a user interface (UI) model of the data. The method further involves providing an instance of an application server coded in JavaScript, for example, in a Node.js cross-platform runtime environment. The instance of the application server coded in JavaScript includes the logic of an application coded to process the data. The application logic is executed (and data processed) on either the client-side or on the cloud-side. The execution of the application logic (and processing of the data) is dynamically switchable between the client-side and the cloud-side.

Abstract: A method includes initiating, at backend server, a process for synchronization of a data record stored locally on a client computing device with a corresponding data record stored in a backend database. The synchronization process includes comparing the hash value of the data record stored locally on the client computing device and the hash value of the corresponding data record stored in the backend database, and based on the comparing, sending information about the corresponding data record stored in the backend database to the client computing device, if needed for updating the data record stored locally on the client computing device.
