The Composite Entity design pattern is aimed at managing a set of interrelated persistent objects as if they were a single entity. It is commonly used in the context of Enterprise JavaBeans (EJB) and similar enterprise frameworks to represent graph-based data structures within business models, enabling clients to treat them as a single unit.
The primary goal of the Composite View design pattern is to compose objects into tree structures to represent part-whole hierarchies. This allows clients to treat individual objects and compositions of objects uniformly, simplifying the management of complex structures.
The Embedded Value design pattern aims to enhance performance and reduce memory overhead by storing frequently accessed immutable data directly within the object that uses it, rather than separately.
Event-Driven Architecture (EDA) is designed to orchestrate behavior around the production, detection, consumption of, and reaction to events. This architecture enables highly decoupled, scalable, and dynamic interconnections between event producers and consumers.
The Front Controller design pattern aims to provide a centralized entry point for handling all incoming web requests, ensuring that request handling is managed consistently and efficiently across an application.
The Gateway design pattern aims to encapsulate the interaction with a remote service or external system, providing a simpler and more unified API to the rest of the application.
