Software Component

A Software Component is a modular unit that provides software functionality (through component interfaces and component implementations).

• AKA: Program Component, Code Module, Software Unit.
• Context:
  • It can (typically) provide Component Functions through interface definitions.
  • It can (typically) implement Component Logic through code implementations.
  • It can (typically) maintain Component State through data management.
  • It can (typically) support Component Integration through module interfaces.
  • ...
  • It can (often) enable Code Reuse through modular design.
  • It can (often) facilitate System Extension through plugin architecture.
  • It can (often) manage Component Dependencys through interface contracts.
  • It can (often) ensure Component Quality through unit testing.
  • ...
  • It can range from being a Simple Component to being a Complex Component, depending on its functionality scope.
  • It can range from being a Stateless Component to being a Stateful Component, depending on its state management.
  • It can range from being a Library Component to being a Service Component, depending on its deployment type.
  • It can range from being a Frontend Component to being a Backend Component, depending on its system layer.
  • ...
  • It can integrate with Software Frameworks for component execution.
  • It can utilize Component Patterns for design implementation.
  • It can incorporate Testing Frameworks for quality assurance.
  • ...
• Examples:
  • Application Components, such as:
    • UI Components, such as:
      • Widget Component for user interaction.
      • Display Component for data visualization.
  • System Components, such as:
    • Service Components, such as:
      • Data Access Component for database operations.
      • Network Component for communication protocols.
  • Framework Components, such as:
    • Extension Components, such as:
      • Plugin Component for system customization.
      • Module Component for functionality extension.
  • ...
• Counter-Examples:
  • Hardware Component, which provides physical functionality.
  • Documentation Component, which provides information content.
  • Process Component, which defines workflow steps.
• See: Software Module, Software Library, Component Architecture, Software Design, Code Organization.
