Component-Based Development
A software engineering approach that emphasizes the separation of functionality into independent, reusable modules called components, each encapsulating distinct features or services.
Component-Based Development
Component-based development (CBD) represents a fundamental shift in how software systems are designed, built, and maintained. This approach emphasizes breaking down complex systems into discrete, self-contained units that can be developed, tested, and deployed independently.
Core Principles
-
Modularity
- Independent functional units
- Clear interfaces and boundaries
- Encapsulation of internal complexity
- Separation of Concerns
-
Reusability
- Components designed for multiple contexts
- Software Reuse across projects
- Reduced development time and costs
- Standardized interfaces
Component Characteristics
Essential Properties
