Facade Pattern and Session Facade

The Facade Pattern is a structural design pattern. It primarily hides complexity, leading some to call it a “good sense pattern.” It also effectively decouples code, which is a significant benefit. However, it’s crucial not to overuse the Facade Pattern in your applications.

Just as excessive abstraction can harm code readability, so too can over-simplification. Introducing too many layers, while seemingly simplifying, can inadvertently add new layers of complexity.

A Session Facade is particularly useful for encapsulating the complexities involved in interactions between a client and a server. It manages business objects and provides a uniform service access layer to clients. Essentially, it acts as a centralized component that minimizes method calls over a network, exposes a consistent interface, and manages security and transactions from a single point.
