System Vision Document

Wayne Johansen has become an active fan of geocaching and would like to keep track of all of his geocaching activities. Rather than use one of the free or commercial web sites, he would like to have his own geocaching system on his own computer. The system will need to have to support several different geocaching types of activities, including listing interesting geocaches and trips that Wayne would like to do, also geocaches that he has found and trips he has taken. In addition, since Wayne also would like to create his own geocaches, he would like to be able to create and describe his own geocaches and track those that he has posted for public use.

This system is essentially an information tracking system. It will need its own database to keep track of all of the information about his activities and his geocaches. Wayne has decided that it would suffice to have a system built to run on his laptop.

System Capabilities

The new system should do the following:

• Keep track of interesting geocache locations that have not been located yet.
• Keep track of geocaches that have been located.
• Record detailed and ancillary information about located geocaches.
• Keep track of new geocaches that are being created by Wayne.
• Keep track of posted geocaches that Wayne has posted to geocaching sites.
• Provide summary information (reports) about Wayne geocache activities.

Application Benefits

This system should provide the following benefits to Wayne:

• Enable Wayne to easily track all of his geocaching trips and find them.
• Enable Wayne to easily create and post new geocaches.
• Allow Wayne to share his geocaching interests with other friends.
• Allow Wayne to update his geocaching information while traveling with his laptop.

1. Identify and clearly describe at least four use cases for this envisioned system.
2. Based on your answer for step 'a,' draw a simple use case diagram. Help draw software for this purpose but you will need to embed this sketch.
3. Select a single use case from the list of use cases in step 'a,' and identify the steps required to perform the use case.
