- Use Configuration Over Customization: Prefer configuration options over custom coding.
- Security Considerations: Ensure customizations do not introduce security vulnerabilities.
6. Describe the process of creating a BI Publisher report.
Creating a BI Publisher report in Oracle Fusion involves:
- Data Model Creation: Define data sources and structure for the report.
- Report Layout Design: Design the report layout using the BI Publisher layout editor.
- Report Generation: Run the report with the data model and layout.
- Report Delivery: Deliver the report via email, FTP, or web services.
7. How do you implement role-based access control (RBAC)?
Role-based access control (RBAC) in Oracle Fusion regulates access based on user roles. To implement RBAC:
- Define Roles: Identify roles within your organization.
- Assign Permissions: Determine permissions for each role.
- Create Role Hierarchies: Establish role hierarchies if necessary.
- Assign Roles to Users: Assign roles based on job functions.
- Review and Audit: Regularly review role assignments and permissions.
Roles are managed through the Security Console, where administrators can create and manage roles and permissions.
8. Explain the concept of Application Composer.
Application Composer in Oracle Fusion allows users to customize and extend applications without extensive coding. Features include:
- Custom Objects: Create custom objects to store additional data.
- Custom Fields: Extend existing objects with custom fields.
- Page Layouts: Modify page layouts to suit business processes.
- Business Logic: Add custom business logic using Groovy scripts.
- Security: Secure custom objects and fields for authorized access.
Application Composer provides a declarative interface, making it accessible to users without a technical background.
9. How do you monitor and manage workflows?
Monitoring and managing workflows in Oracle Fusion involves using built-in tools and administrative features. Key components include:
- Oracle BPM Worklist: Manage tasks and track workflow progress.

Example:
SELECT user_id, username, email
FROM users
WHERE status = 'ACTIVE';
In this query:
user_id
, username
, and email
are the columns you want to retrieve.
users
