Mountain Hiking Database
A popular hiking club has asked you to create a database that shows information about mountains
to hike on in the United States. For serious club members, extra information is provided about
the 25 top 14ers (14ers are mountains over 14,000 ft in elevation). The database includes the
name of the mountain, the location (Range, State, County, summit GPS coordinates), the name of
the trailhead, the hike distance one way and round trip, the hike difficulty (easy, moderate, hard),
the elevation in feet at the summit, the elevation gain during the hike. For the 14ers, the members
also see data about any special gear needed and whether or not camping is required to
accomplish
the hike. When club members use your database, they enter their name, date of birth, the state
and county that they live in, the date of each hike to any summit theyve accomplished, the time it
took them to reach the summit and their round trip time. Two other national clubs for hiking also
send hiker data to the Mountain Hiking Database. They import their users as members of this
club too (a dual membership) because their members can track their hikes here once they have an
account.
[1] This database offers users a list of top 25 14ers and details about those hikes.
[2] Users can see the number of hikes represented in each difficulty level.
[3] They can get a list of the hikes theyve already done and the list is in date order with
their age at the time of each hike.
[4] For each 14er, the database lists all of the hikers who have climbed it and reports the
average age of hikers on that peak and the average hiking speed to the summit and for a
round trip.
[5] Hikers are recognized with a trophy sent to their address when they have hiked all 25
of the top 14ers.
[6] Hikers are recognized with a walking stick icon and their photo on a high achievers
page when they have hiked more than 1000 miles in the mountains of the United States.
