Abstract: The present invention provides for data to be bilaterally transferred between general applications such as databases and task specific applications. The transfer maps and transports data between applications. The first application includes a data structure with a data structure identifier and a table. The second application includes a data grid. The mapping of data is performed by: associating a column in the grid to a table data field; associating a mapping icon with the column; and associating the table identifier with the column. The transporting of data between the applications include: identifying a transport function; identifying at least one of the mapping; and transporting data according to the selected mapping and the selected transport function.
