Intent of Anti-Corruption Layer Design Pattern
The Anti-Corruption Layer (ACL) is a crucial design pattern in Java development, particularly for system integration and maintaining data integrity. Implement a façade or adapter layer between different subsystems that don't share the same semantics. It translates between different data formats and systems, ensuring that the integration between systems does not lead to corruption of business logic or data integrity.

- Service Representative
Intent of Business Delegate Design Pattern
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.
Intent of Clean Architecture.
To organize the system so that the core business logic remains independent from external concerns and frameworks.
Detailed Explanation of Clean Architecture Pattern with Real-World Examples
Real-world example
Imagine a large pizza chain with multiple ordering channels—web, mobile app, phone calls, and in-store kiosks. The core “pizza domain” logic (calculating prices, preparing orders, managing loyalty points) is kept entirely separate from the user interfaces and storage mechanisms. As a result, the chain can add or change the ordering channel (for example, introducing a chatbot or swapping out the database) without altering the fundamental pizza-ordering rules, thanks to the layered boundaries and strict dependency rules of Clean Architecture.
Also known as
- Data Access Layer
- DAO
Intent of Data Access Object Design Pattern
The Data Access Object (DAO) design pattern aims to separate the application's business logic from the persistence layer, typically a database or any other storage mechanism. By using DAOs, the application can access and manipulate data without being dependent on the specific database implementation details.
Also known as
- Transfer Object
- Value Object
Intent of Data Transfer Object Design Pattern
The Data Transfer Object (DTO) pattern is used to transfer data between software application subsystems or layers, particularly in the context of network calls or database retrieval in Java applications. It reduces the number of method calls by aggregating the data in a single transfer.
Also known as
- Conceptual Model
- Domain Object Model
Intent of Domain Model Design Pattern
The Domain Model pattern aims to create a conceptual model in your software that matches the real-world system it's designed to represent. It involves using rich domain objects that encapsulate both data and behavior relevant to the application domain, ensuring business logic is centralized.
Also known as
- Centralized Request Handling
Intent of Front Controller Design Pattern
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.
Also known as
- Ports and Adapters
Intent of Hexagonal Architecture Design Pattern
Hexagonal Architecture, also known as Ports and Adapters, is a design pattern in Java that promotes decoupling of core business logic from external interfaces like databases and user interfaces. This architectural approach enhances maintainability and testability of software systems.
Intent of Intercepting Filter Design Pattern
The Intercepting Filter Pattern in Java is a powerful design pattern that allows for efficient web request handling. This pattern enables the application of multiple filters in a filter chain to process and modify requests and responses.

Also known as
- N-Tier Architecture
Intent of Layered Architecture Design Pattern
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.
