Layered Architecture: This pattern is commonly used in large-scale enterprise applications where separation of concerns, scalability, and maintainability are key considerations. For example, a web-based e-commerce application might be structured into separate layers for presentation (UI), business logic, and data access, allowing each layer to be developed, tested, and maintained independently. Structural Architecture: This pattern is commonly used in applications where the data model is complex and relationships between data entities are important. For example, a database-driven application such as a financial management system or a hospital patient management system might use a structural architecture to organize the code around data structures such as tables, records, and fields. Presentational Architecture: This pattern is commonly used in web and mobile applications where there is a clear separation between the presentation layer and the domain layer. For example, a mobile banking...

  Architecture Pattern Definition Key Characteristics Pros Cons Layered A pattern in which the application is divided into logical layers, each responsible for a specific function Separation of concerns, modular design, easier maintenance and testing, scalability Clear separation of layers simplifies maintenance and testing, promotes code reuse, supports parallel development May introduce performance overhead due to communication between layers, may be difficult to implement in small projects Structural A pattern that organizes the code around the data structures used in the application Emphasizes data structures and their relationships, promotes reusability of code, simplifies maintenance and testing, supports parallel development Easier to understand and modify code, promotes code reuse, supports parallel development Can be less flexible when requirements change, may not be suitable for projects with complex business logic Presentational A pattern in which the application is sepa...
