Redesign applying the Facade pattern

[gsus25]

The suggestion is to apply the Facade pattern to the existing code by creating the InmigrationFacade class to simplify the interface and enhance modularity. This class will act as a unified interface, encapsulating the complexities of the CovidRegistration, MedicalTest, TbTestsStatus, and TravelGuide classes. The proposal involves providing cohesive methods in InmigrationFacade, such as registerForCovid, medicalTest, tbTestsStatus, and travelGuide, hiding the internal complexity. This approach not only simplifies the user experience but also improves code maintainability by isolating the underlying classes and facilitating future updates.

Consequences: • Simplified Interface: End-users will interact with a unified and coherent interface, reducing complexity and enhancing understanding of immigration functionalities. • Improved Maintainability: Isolating underlying classes facilitates future modifications and updates to internal implementations without affecting the external interface. • Increased Modularity: The introduction of InmigrationFacade enhances system modularity by providing a clear entry point and separating responsibilities of specialized classes.
