Bridge
Bridge is a structural design pattern in software engineering that decouples an abstraction from its implementation, allowing them to vary independently. It involves separating a class into two hierarchies: one for abstraction and another for implementation, connected through a bridge interface. This pattern is used to avoid a permanent binding between abstraction and implementation, enhancing flexibility and scalability in complex systems.
Developers should learn and use the Bridge pattern when designing systems where abstraction and implementation need to evolve separately, such as in cross-platform applications or when supporting multiple database drivers. It is particularly useful for avoiding a proliferation of classes in scenarios like GUI toolkits or device drivers, as it reduces coupling and simplifies maintenance by allowing changes on one side without affecting the other.
