Software architecture patterns are reusable solutions to commonly occurring problems in software design. They provide guidelines and best practices for structuring and organizing the codebase to achieve specific goals such as scalability, maintainability, and reliability. Understanding different software architecture patterns is crucial for software developers and architects as it helps them make informed decisions when designing and implementing systems. Here's an overview of software architecture patterns, including their methods, types, and importance:
1. Understanding Software Architecture Patterns:
Software architecture patterns are high-level structures that provide a blueprint for organizing and designing software systems. They define the overall layout and interaction of components within a system and guide developers in making design decisions.
2. Methods of Software Architecture Patterns:
Software architecture patterns can be categorized based on their method of organization and control flow. Some common methods include:
a. Structural Patterns:
- Structural patterns focus on organizing the structure of a software system. They define how components and modules should be organized and interact with each other. Examples include: Layered Architecture
- Model-View-Controller (MVC)
- Microservices Architecture
b. Behavioral Patterns:
- Behavioral patterns describe the interaction between objects and the flow of control within a system. They define how objects communicate and collaborate to achieve specific tasks. Examples include: Observer Pattern
- Command Pattern
- State Pattern
c. Creational Patterns:
- Creational patterns are concerned with object creation mechanisms, trying to create objects in a manner suitable to the situation. They focus on hiding the creation logic and making the system independent of how its objects are created, composed, and represented. Examples include: Singleton Pattern
- Factory Method Pattern
- Builder Pattern
The subsequent discussion revolves around major android architecture, underlying components, and their basic usage.
It starts with analysis and planning, designing the wireframes + prototype, implementing the design into code, testing the code, deployment or production and deployment of software.
Architectural guidelines must be followed throughout the development process, as these help in writing the software in a disciplined and well-structured approach.
Of course, a well-written application is good to test, can be easily scaled up and maintained.
This pattern was laden with issues as usual like in case developer choose to adopt a Model View Presenter Pattern, they needed to come up with their solution from scratch, involved a lot of coding efforts (might be directionless), or adopt a library without any official support (Google).
Android architecture comes with four components, each with a specific role to lift up the burden of underlying architecture: Room, ViewModel, LiveData, and Lifecycle.
