No industry group has yet defined XML tags suitable for the RTGM application. Thus, designers must develop appropriate tags for this application. If you aren’t already familiar with XML, do at least 30 minutes of background research on the Web. Refer to the class diagram in the Chapter 4 RTGM case to determine required data content. Then, design XML tags and message formats suitable to transmit time-stamped glucose levels from the cell phone app to the server and to transmit updated alert conditions from the server to the cell phone app. If medical personnel choose to send a text message to the patient, how will the server transmit that message? To help answer that question, research Short Message Service (SMS), Enhanced Messaging Service (EMS), and SMS gateways.
