A method for reducing the latency time for interactive data communication between a server computer ( 6 ) and a client computer ( 2 ) via a satellite network ( 4 ) comprising a geostationary satellite ( 12 ), whereby a data processing application ( 14 ), in particular a database application, runs on the server computer ( 6 ) and generates screen displays of an interactive user application with several data fields ( 18 ) that are processed one after the other in a processing sequence in line with predetermined parameters (# 1, #2, #3 ) based on commands and data entered via an input medium ( 30 ) connected to the client computer ( 2 ), and then transferred to the client computer ( 2 ) in the form of data packets essentially without acknowledgment of receipt and displayed by this client computer ( 2 ) on a display medium ( 26 ), whereby an input prompt ( 7 ) on the display medium ( 26 ) signalizes that additional data is to be entered in a corresponding data field ( 18 ) via the input medium and then transferred in the form of additional data packets via the telecommunication network ( 4 ) to the server computer ( 6 ), wherein the parameters (# 1, #2, #3 ) for the processing sequence of the data fields ( 18 ) are transmitted via the satellite network ( 4 ) to the client computer ( 2 ); and an independent program routine ( 22 ), which runs on the client computer ( 2 ), alters the screen display independently in such a way when entering specified commands via the input medium ( 30, 32 ) based on the parameters (# 1, #2, #3 ) for the processing sequence that the input prompt ( 7 ) within a data field ( 18 ) is moved to the next or previous data field in line with the processing sequence.
