1. A method for transferring data, the method comprising:

  • sending, from a receiving device, a data query to request the data from a sending device;

    receiving, from the sending device, a result model in response to the data query, the data result model including a table block;

    analyzing the data result model to regenerate the data for storage at the receiving device, wherein analyzing the result model 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,determining the number of columns in the table block from the column definition,analyzing the row flag to determine whether the data row includes null values and, when the row flag indicates the presence of null values, further analyzing the null location list to determine location information for non-null and null values, andcreating at least one mapped data row by sequentially inserting the non-null data from the row payload field at non-null locations and inserting a null value at each null location determined in the analyzing step; and

    processing each mapped data row to provide the regenerated data for storage at the receiving device.
