Redesign applying the Composite pattern

[gsus25]

Proposal: It is proposed to implement the Composite pattern to hierarchically structure entities such as products, categories, and shopping carts in the project. A common interface will be created to allow clients to interact uniformly with individual products and categories, facilitating standard operations like adding, removing, and retrieving information. The introduction of the Composite pattern aims to simplify the manipulation of the product and category structure consistently, promoting code reusability, and facilitating the system's expansion into future functionalities.

Consequences: • Uniform Interaction: The implementation of the Composite pattern will provide a consistent interface for products and categories, allowing consistent operations and simplifying client interaction. • Flexibility and Extensibility: By treating products and categories uniformly, the system's flexibility to build complex structures is enhanced. Additionally, adopting the Composite pattern facilitates the introduction of new functionalities without substantial modifications to existing code. • Code Simplification and Coherence: The Composite pattern centralizes common operations in a shared interface, simplifying the code and increasing coherence in the manipulation of products and categories. This results in more maintainable and easily understandable code.
