CBD

Component-Based Development (CBD) is a software development approach in which systems are constructed and reused through components that define clear responsibilities, contracts, and interfaces. Components are designed to be independent and replaceable, enabling loosely coupled architectures that improve maintainability and reusability. In the logical model, a component serves as an abstract structural unit defining functionality and contracts; in the physical model, it corresponds to implementation and deployment units.

In the AI era, CBD is being redefined as a structured development foundation that AI can interpret, design, and optimize. In the SimpleModeling approach, components’ responsibilities, contracts, and dependencies are expressed through literate models and DSLs (CML) in a form understandable by AI, enabling AI-assisted design, verification, generation, and integration—an AI-collaborative form of CBD.
