Patterns

Monolith

The Monolith is a traditional software architectural style that structures an application as a single, self-contained unit. All components – user interface, business logic, data access, and database – are bundled together and deployed as one. This approach simplifies initial development and deployment, as everything …

Multiton

creational

The Multiton pattern is a variation of the Singleton pattern. While a Singleton restricts the instantiation of a class to only one instance, a Multiton allows a limited number of instances. This is useful when multiple instances are needed to represent different, but related, states or configurations without allowing …

MVC

behavioral architectural

The Model-View-Controller (MVC) pattern is a widely used architectural pattern for developing user interfaces. It divides an application into three interconnected parts: the Model, which manages the application’s data and logic; the View, which displays the data to the user; and the Controller, which handles user …

MVP

architectural behavioral

The Model-View-Presenter (MVP) pattern is a user interface architectural pattern that originated from a desire to improve the separation of concerns in graphical user interface (GUI) development. It’s similar to Model-View-Controller (MVC), but with a key difference: the View in MVP is entirely passive, …

MVVM

architectural behavioral

MVVM (Model-View-ViewModel) is an architectural pattern that facilitates the separation of an application’s concerns – data presentation (View), interaction logic (ViewModel), and data management (Model). It’s primarily used in conjunction with data binding, allowing automatic synchronization of data between the …

N-Tier

architectural structural

The N-Tier pattern is an architectural pattern that organizes an application into distinct layers, each responsible for a specific aspect of the application. These tiers are logically and physically separated, promoting modularity, maintainability, and scalability. Common tiers include the Presentation Tier (UI), …

Onion Architecture

architectural DDD

Onion Architecture is a software design pattern that advocates for separating concerns into distinct layers, with the core business logic residing at the very center. This central core is independent of any external concerns like databases, UI frameworks, or external services. Layers represent different levels of …

Page Controller

behavioral web

The Page Controller pattern is a simple and straightforward approach to handling user requests in web applications. It centralizes request handling logic within a controller, which is responsible for determining which data needs to be fetched, preparing the data, selecting the appropriate view, and rendering the final …

Peer-to-Peer

distributed structural networking

The Peer-to-Peer (P2P) pattern is a distributed application architecture that eliminates the need for a central server. Instead, individual nodes (peers) in the network share resources directly with each other. Each peer acts as both a client and a server, contributing its own resources (storage, bandwidth, processing …

Pipes and Filters

behavioral data processing

The Pipes and Filters pattern is a data processing paradigm where a series of independent processing components (Filters) are connected by channels (Pipes). Each Filter performs a specific transformation on the input data and passes the result to the next Filter in the pipeline. The pattern promotes modularity, …
