                        "This move 
                        extends our Unwired Enterprise strategy and positions 
                        Sybase to play a pioneering role in the next technology

                        time."

                        users. 
                        "We have 
                        very strong partnerships with both Sybase and Dejima and 
                        feel that this is a match made in heaven," said Marc 
                        Benioff, chairman & CEO, salesforce.com. "Joining

                        technology with Sybase's robust data management,
