Oracle Fusion Applications Architecture

Oracle Fusion Applications architecture is based on a service-oriented architecture (SOA) and utilizes Oracle Fusion Middleware technology. It is designed to provide a scalable, flexible, and integrated enterprise application suite. Here are the key components and layers of the Oracle Fusion Applications architecture:

1. Presentation Layer: The presentation layer is the user interface (UI) layer that allows users to interact with Oracle Fusion Applications. It provides a web-based interface accessible through browsers or mobile devices. The UI layer is built using technologies like HTML5, JavaScript, and Oracle Application Development Framework (ADF).

2. Application Layer: The application layer consists of various modules and functional areas within Oracle Fusion Applications, such as Financials, Human Capital Management (HCM), Supply Chain Management (SCM), Customer Relationship Management (CRM), and more. Each module provides specific business functionalities and processes.

3. Service-Oriented Architecture (SOA) Layer: The SOA layer is a key component of the Oracle Fusion Applications architecture. It enables seamless integration and interoperability between different modules and external systems. It provides a set of services and connectors for data exchange, process orchestration, and integration with other applications.

4. Oracle Fusion Middleware: Oracle Fusion Middleware is the underlying technology platform for Oracle Fusion Applications. It includes components such as Oracle WebLogic Server, Oracle SOA Suite, Oracle Identity and Access Management, Oracle Business Intelligence, and more. These components provide the infrastructure, tools, and services for building, deploying, and managing the applications.

5. Data Layer: The data layer consists of the Oracle Database, where the application data is stored. The Oracle Database provides a reliable, scalable, and secure data management platform for Oracle Fusion Applications. It stores transactional data, configuration data, and metadata related to the application modules.

6. Security and Identity Management: Oracle Fusion Applications incorporate robust security and identity management capabilities. This includes authentication, access controls, data encryption, and user provisioning. Oracle Identity and Access Management (IAM) components are used to manage user identities, roles, and permissions.

7. Reporting and Analytics: Oracle Fusion Applications offer reporting and analytics capabilities for data analysis and decision-making. This includes prebuilt reports, dashboards, and ad-hoc query tools. The reporting and analytics layer integrates with Oracle Business Intelligence (BI) tools for advanced reporting and data visualization.

8. Integration and Extensibility: Oracle Fusion Applications provide various integration methods and tools to integrate with other systems and extend the functionality. This includes web services, application programming interfaces (APIs), and tools like Oracle Application Development Framework (ADF) for building customizations and extensions.

The architecture of Oracle Fusion Applications is designed to provide a comprehensive, modular, and scalable solution for organizations. It enables seamless integration, flexible deployment options, and a unified user experience across different functional areas.
