A use case diagram is a visual representation of the interactions between a system and its users, or actors, in a particular environment. It is a valuable tool for understanding the functionality of a system and identifying the primary and secondary goals of its users. In the context of an online hotel reservation system, a use case diagram can help to illustrate the various ways in which a user may interact with the system in order to search for, select, and reserve a hotel room.
There are several actors that may be involved in an online hotel reservation system, including the guest, the hotel staff, and the system administrator. The guest is the primary actor, as they are the ones who initiate the process of searching for and reserving a hotel room. The hotel staff and the system administrator are secondary actors, as they are responsible for managing the availability of rooms and ensuring the smooth operation of the system.
The primary goal of the guest is to find and book a suitable hotel room at a convenient location and price. In order to achieve this goal, they may need to perform a number of different tasks, including:
Searching for available rooms: The guest can use the system to search for available rooms based on a variety of criteria, such as location, price range, and room type.
Viewing room details: Once the guest has found a room that meets their needs, they can view detailed information about the room, including its size, amenities, and availability.
Making a reservation: If the guest decides to book the room, they can use the system to complete the reservation process, which may involve entering personal and payment information.
Cancelling or modifying a reservation: If the guest needs to cancel or modify their reservation, they can use the system to do so.
In addition to these primary goals, there are also a number of secondary goals that may be relevant for the guest, such as:
Receiving confirmation of the reservation: After the guest has completed the reservation process, they should receive confirmation that their booking has been successful.
Viewing and printing a reservation itinerary: The guest may want to view and print a summary of their reservation, including the details of their stay and any additional services or amenities they have requested.
Receiving notifications or updates: The guest may want to receive notifications or updates from the hotel or the system, such as confirmation of their reservation or changes to their itinerary.
The hotel staff and the system administrator also have their own goals and tasks related to the online hotel reservation system. The staff may be responsible for managing the availability of rooms and handling any requests or queries from guests, while the administrator may be responsible for maintaining and updating the system itself.
In summary, a use case diagram for an online hotel reservation system can provide a useful overview of the various interactions and goals of the system's actors, including the guest, the hotel staff, and the system administrator. It can help to identify the primary and secondary goals of each actor and understand the various tasks and processes involved in searching for, selecting, and reserving a hotel room.
