In a hotel booking application, which properties should be considered target properties?

In a hotel booking application, the total cost for the hotel room is a target property because it represents the primary outcome of a customer’s booking decision. This property encapsulates the financial commitment made by the user and is crucial for the application to present a comprehensive view of the booking.

The total cost for the hotel room directly impacts the business's financial metrics and user satisfaction, making it critical for calculations, reporting, and decision-making processes within the application. This property ensures that both users and the hotel management can see the final price that reflects the various factors involved in the booking, such as seasonal rates, promotions, or cost increases based on demand.

In contrast, while the number of days at the hotel, the total cost of options, and the price of each option are relevant data points, they are either components of or related to the total cost and may not serve as standalone target properties for tracking the overall booking expense. Therefore, focusing on the total cost for the hotel room aligns best with the objectives of understanding and managing the booking process effectively.
