Singleton Pattern

[Jazarumag]

The Singleton pattern could be used to centralize and manage information related to immigration processes in a single instance. It provides global access to functions such as medical registration, document verification, and travel guidance, facilitating consistent interaction with immigration data. Attached UML:

Positive Consecuences:

• Ensures a single access point to the TravelGuideBuilder instance, avoiding the creation of multiple instances and ensuring consistency in the construction of the object.
• By ensuring that only one instance exists, you save memory and processing resources that would be used to create additional unnecessary instances. Negative Consecuences:
• It can introduce strong coupling into the code, as the Singleton pattern can be globally accessible, which can make components directly depend on it.
