ABSTRACT:
A method and apparatus for is provided for efficiently transmitting multiple rows of data to a client station. The client station generates a query that is transmitted to a remotely located server, which in turn generates a query result. The server transmits the first row of data from the query result to the client. The remaining rows of data are transmitted by first calculating the difference between successive rows of data. Next, the server sends only the unique rows resulting from the calculated row difference to the client. The server also send an indication of the number of non-repeated value columns detected in order to allow reconstruction of the query result by the client station.
