1. Create a comprehensive and detailed  Activity UML diagram with ten or more elements or nodes.

2. Create a  Use Case UML diagram that illustrates the interactions between a doctor and the Mentcare system. Identify use cases with at least 4 other user groups, such as receptionists, medical records staff, the Human Resources Department, Legal Department, Pharmacy, Safety, Finance Department, potentially the patient population, etc.  Create a comprehensive and detailed use case diagram containing at least five such actors.

3. Compare and contrast the two different diagramming approaches and how the goals of each vary. This short essay should be between 100 and 150 words.

2.Create a  UML Activity Diagram for the Wilderness Weather Station that tracks the flow of weather data from the Satellite box into the archival database.

This diagram does not need to account for error handling or human intervention.

I expect this will contain a minimum of 20 elements and will span all three sub components of the Wilderness weather station.  Label each sub component in some way - such as a color, a number, a different shape, or something.  Whatever you do, do so in such a way that it is easy for me to see "this is part of the satellite box" and "this is part of the control panel".
