ABSTRACT:
Systems and methods are provided for transferring data. In one implementation, a method is provided for transferring data between a sending device (e.g., a server) and a receiving device (e.g., a client). The method may include sending, from the receiving device, a data query to request data from the sending device and receiving, form the sending device, a data result model in response to the data query. The data result model may include a table block. The method may also include analyzing the data result model to regenerate the data for storage at the receiving device. Analyzing the data result model may comprises reading at least one column definition and at least one data row from the table block, the data row including a row flag, a null location list, and a row payload field including the non-null data to be transferred to the receiving device. The method may further include processing each mapped data row to provide the regenerated data for storage at the receiving device.
