The Business Delegate pattern is a structural design pattern in Java that adds an abstraction layer between the presentation and business tiers. By using the pattern we gain loose coupling between the tiers and encapsulate knowledge about how to locate, connect to, and interact with the business objects that make up the application.
The Composite Entity design pattern in Java is aimed at managing a set of interrelated persistent objects as if they were a single entity. It is commonly used in enterprise applications, particularly within the context of Enterprise JavaBeans (EJB) and similar enterprise frameworks, to represent graph-based data structures within business models. This pattern enables clients to treat these complex structures as a single unit, simplifying operations and interactions.
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 hierarchical views.
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. This pattern ensures consistent and efficient request routing and management across a Java web application.
The Gateway design pattern is a crucial concept in Java design patterns for simplifying API integration and interactions with remote services. It provides a unified and simplified interface to external systems, enhancing the maintainability and architecture of applications. By encapsulating these interactions, the Gateway pattern ensures loose coupling and promotes a more modular and scalable software design, making it essential for robust and efficient application development.
The Identity Map design pattern in Java aims to ensure that each object gets loaded only once by keeping every loaded object in a map, enhancing database performance and memory management.
The Layered Architecture design pattern helps organize applications into groups of subtasks at different levels of abstraction, facilitating independent development and maintenance of each layer.
Metadata Mapping Design Pattern is designed to manage the mapping between database records and Java objects in a way that keeps the database schema and object model decoupled and manageable.
The API Gateway design pattern aims to provide a unified interface to a set of microservices within a microservices architecture. It acts as a single entry point for clients, routing requests to the appropriate microservices and aggregating results, thereby simplifying the client-side code.
