kehysarkkitehtuuria

Kehysarkkitehtuuria, or framework architecture, refers to the underlying structure and principles that guide the design and implementation of software frameworks. A framework is a reusable set of software components and libraries that provides a common foundation for developing applications. Kehysarkkitehtuuria defines how these components interact, what rules govern their behavior, and how developers can extend or customize the framework to meet specific needs.

Key aspects of kehysarkkitehtuuria include the separation of concerns, where different parts of the framework are responsible for distinct functionalities. This promotes modularity and maintainability. Another important principle is inversion of control, often referred to as the Hollywood principle ("Don't call us, we'll call you"). In this model, the framework dictates the flow of execution and calls upon the developer's code when needed, rather than the developer's code directly controlling the framework.

Common patterns found in kehysarkkitehtuuria include Model-View-Controller (MVC), Model-View-ViewModel (MVVM), and Aspect-Oriented Programming (AOP). These patterns help organize code, manage data, and handle cross-cutting concerns like logging or security. Understanding the kehysarkkitehtuuria of a particular framework is crucial for developers to effectively use it, contribute to its development, and build robust and scalable applications. It provides a blueprint for how an application should be structured within the confines of the chosen framework.
