Presentation Layer

The Presentation Layer provides a way to visually respresent data stored in the database. It transforms and presents data from the Business Layer, which provides data assembled and configured, into suitable formats within the application for the users. It includes components such as Menu, Screen, Component, and Control.

1. Menu: This is the same as the categories in the library, dividing the collection of books into different genres or subjects as fiction, business, etc.
2. Screen: Similar to the layout of the library itself, where the shelves and functionalities are organized, screens in the Presentation Layer organize the components and controls.
3. Component: Components resembe shelves in the library, where multiple books (controls) are housed together. Each component can represent a section of the library containing related books.
4. Control: Controls are like individual books within a shelf(component). Controls are the smallest unit of the information management, allowing users to interact with and access specific data.
