Aspect-Oriented Programming (AOP) is a programming paradigm that focuses on separating cross-cutting concerns from the main business logic of a program. In traditional programming approaches, such as Object-Oriented…

Command Query Responsibility Segregation (CQRS) is a software architecture pattern that separates the responsibilities of reading data (queries) and writing data (commands) into two distinct models. Instead of…

Domain-Driven Development (DDD) is a software design approach introduced by Eric Evans in his book Domain-Driven Design: Tackling Complexity in the Heart of Software. At its core, DDD…

Inversion of Control (IoC) is a design principle in software engineering that shifts the responsibility of controlling the flow of a program from the developer’s custom code to…

A Minimum Viable Product (MVP) is the most basic version of a product that still delivers value to users. It is not a full-fledged product with every feature…

Separation of Concerns (SoC) is a foundational design principle: split your system into parts, where each part focuses on a single, well-defined responsibility. Done well, SoC makes code…

State is the “memory” of a system—the data that captures what has happened so far and what things look like right now. State management is the set of…

Tight coupling is when one component depends directly on the concrete implementation, lifecycle, and behavior of another. If A changes, B likely must change too. This is the…

Dependency Injection (DI) is a design pattern in software engineering where the dependencies of a class or module are provided from the outside, rather than being created internally.…

Loose coupling is a design principle in software engineering where different components, modules, or services in a system are designed to have minimal dependencies on one another. This…

Model-View-ViewModel (MVVM) is a software architectural pattern that helps organize code by separating the user interface (UI) from the business logic. It acts as an evolution of the…

MVC stands for Model–View–Controller, a popular architectural pattern used in software engineering. An MVC framework provides a structured way to separate concerns in an application, making development, testing,…

The Waterfall Model is one of the earliest and most traditional approaches to software development. It follows a linear and sequential design process, where each phase must be…

A modular monolith is a software architecture style where an application is built as a single deployable unit (like a traditional monolith), but internally it is organized into…
