As the lead software engineer for a medium-sized hospital, you have been asked to spearhead an effort to improve the tracking of Voice Over IP (VOIP) calls made within the hospital system. You have also been asked to begin planning out an emergency vehicle discovery program that will improve the response times of medical personnel to remote emergency locations by pinpointing the closest vehicle to the emergency using GPS.
Design the Requires and the Provides interfaces of at least two (2) components that might be used in a system in an emergency control room for a call-logging component that records calls made.
Design the interfaces of at least two (2) components that might be used in a system in an emergency control room for a vehicle discovery component that, given a post code (zip code) and an incident type, finds the nearest suitable vehicle to be dispatched to the incident.
Include both the Requires interface and the Provides interface in your design.
Develop a visual rendering depicting your design through the use of Microsoft Visio or its open source alternative, Dia.
