Mountain Peak Adventures $($MPA$)$ is a premier guide service company that organizes and conducts hiking and climbing expeditions in various mountain ranges across North America. The company needs a new information system to manage their operations effectively.

MPA employs experienced guides who must be certified in first aid, mountain rescue, and specific terrain specialties. Each guide is assigned a mentor from the other guides, sharing their expertise in particular skills. Each guide can mentor several $($or no$)$ other guides. Guides can lead multiple expeditions throughout the season, and complex expeditions often require multiple guides working together.

Clients book expeditions through MPA's booking system. Each expedition has specific requirements for fitness levels, experience, and necessary equipment. Clients can participate in multiple expeditions throughout the year, and each expedition can accommodate multiple clients up to a safety$-$determined maximum capacity. Before joining an expedition, clients must complete a medical clearance form and sign a liability waiver.

MPA also tracks various mountain routes, each with detailed information about difficulty ratings, seasonal accessibility, typical weather conditions, and required permits. Routes can be combined to create different expeditions, and the same route might be used in multiple expeditions throughout the season. The company maintains detailed logs of each completed expedition, including weather conditions encountered, any incidents or notable events, and client feedback.
