Compare different architectural patterns

 

Architecture PatternDefinitionKey CharacteristicsProsCons
LayeredA pattern in which the application is divided into logical layers, each responsible for a specific functionSeparation of concerns, modular design, easier maintenance and testing, scalabilityClear separation of layers simplifies maintenance and testing, promotes code reuse, supports parallel developmentMay introduce performance overhead due to communication between layers, may be difficult to implement in small projects
StructuralA pattern that organizes the code around the data structures used in the applicationEmphasizes data structures and their relationships, promotes reusability of code, simplifies maintenance and testing, supports parallel developmentEasier to understand and modify code, promotes code reuse, supports parallel developmentCan be less flexible when requirements change, may not be suitable for projects with complex business logic
PresentationalA pattern in which the application is separated into presentation and domain layersPromotes separation of concerns, modular design, easier maintenance and testing, supports parallel developmentAllows for separate development of UI and business logic, promotes reuse of presentation componentsCan be difficult to implement for large or complex projects
Service-OrientedA pattern that emphasizes the use of independent, loosely-coupled servicesPromotes separation of concerns, modularity, and scalabilitySupports reuse and interoperability of services, easier to scale and maintain individual services, reduces coupling between componentsCan introduce performance overhead due to communication between services, may require additional infrastructure and management overhead
HybridA pattern that combines multiple architectural patterns to meet specific project requirementsOffers flexibility to adapt to project needs, supports modularity, and scalabilityCan leverage the strengths of different patterns, provides a tailored solution to specific project requirementsCan be complex to design and maintain, may require additional development time and cost

Sample use cases for each of the architectural patterns

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...
