Bridge Design Pattern

 The Bridge Design Pattern is a structural pattern that separates an abstraction from its implementation so that both can evolve independently. This pattern is useful when you need to decouple an abstraction from its implementation, allowing them to vary independently without affecting each other. The Bridge Pattern is particularly effective in scenarios where you have multiple variations of both an abstraction and its implementation.

 Real-Time Use Cases for the Bridge Pattern

1. Database Connectivity

  • Scenario: A data access layer needs to support multiple databases (e.g., MySQL, PostgreSQL, Oracle) and provide a unified interface for database operations.
  • Bridge Use Case: Create an AbstractDatabaseConnection class and an IDatabaseImplementor interface. Implementations like MySQLConnection and PostgreSQLConnection provide database-specific functionality. This setup allows for adding new databases without changing the data access interface.

2. Notification Systems

  • Scenario: A notification system needs to support various notification channels (e.g., email, SMS, push notifications) and provide a unified notification interface.
  • Bridge Use Case: Define an AbstractNotification class and a NotificationChannelImplementor interface. Implementations like EmailNotification and SMSNotification handle specific channels. This design allows for adding new notification channels or modifying existing ones without changing the notification system interface.
