Connector Design

Principal objective of Component Based Development

• Rapid development of software products from a kit of components.

• Change the functionality of an assembled product just by reconfiguring its components.
   

The Usual Approach

• An Interface specifies list of operations a Component performs.

• Little attention paid to interaction that must exist over time between components.
   

Connector Based Approach

• Uses Connectors to model the interactions. A Connector is an abstract representation of the interaction between the components it connects.

• Powerful technique for Designing Component Infrastructures
  with replaceable parts.
