Oracle Fusion Applications is a suite of business software applications developed by Oracle Corporation. It encompasses various modules covering various aspects of business operations, including financials, human resources, supply chain management, customer relationship management, and more. The technical aspects of Oracle Fusion Applications involve a combination of technologies and tools, and understanding them requires a strong foundation in Oracle technologies, database concepts, and application development.

Here’s a general overview of the technical aspects you might encounter when working with Oracle Fusion Applications:

1. Oracle ADF (Application Development Framework): ADF is a Java-based development framework used to build rich web applications that are compatible with Oracle Fusion. It provides a set of pre-built components and services for creating user interfaces, business logic, and data services.
2. Oracle WebLogic Server: WebLogic is the application server used to deploy and run Oracle Fusion Applications. It provides a platform for hosting Java EE applications, including those built using ADF.
3. Oracle SOA Suite (Service-Oriented Architecture): SOA Suite is used for integrating various components and services within the Fusion Applications environment. It enables the creation, deployment, and management of services and integrations.
4. Oracle Fusion Middleware: Fusion Middleware includes a collection of tools, technologies, and middleware components that facilitate the development, deployment, and management of Fusion Applications.
5. Oracle Database: Fusion Applications rely on an Oracle Database to store and manage data. Understanding database concepts, SQL, and PL/SQL is crucial for working with Fusion Applications.
6. Oracle Fusion Security: Security is a critical aspect of any business application. Oracle Fusion Security encompasses user authentication, authorization, and role-based access control.
7. Oracle Identity Management: This component is responsible for managing user identities, including user provisioning, single sign-on, and user lifecycle management.
8. Web Services and REST APIs: Fusion Applications expose various functionalities through web services and REST APIs, allowing integration with other systems and custom development.
9. Customization and Extensibility: Fusion Applications can be customized and extended to meet specific business requirements. This involves developing custom ADF components, extending data models, and integrating new functionalities.
10. Oracle Cloud Infrastructure (OCI): If you are working with Oracle Fusion Cloud, you may need to understand how to deploy and manage Fusion Applications in the Oracle Cloud Infrastructure environment.
