Oracle Integration Cloud Enterprise (OIC) is a comprehensive solution to facilitate integration between various applications, both in the cloud and on-premises. 

1.     Pre-Built Integrations: OIC provides pre-built connectors and integrations for many popular Oracle and non-Oracle applications, enabling quick and seamless connectivity.

2. Visual Development Environment: Users can design and build integrations using a graphical, drag-and-drop interface. This enables faster development without needing extensive coding skills.

3. Process Automation: It offers tools to design, automate, and manage business processes. This helps in orchestrating complex workflows across various applications and systems.

4. API Management: OIC enables the creation, deployment, and management of APIs. This makes it easier to expose and consume services across different systems.

5. Hybrid Integration: The ability to connect cloud-based applications with on-premises systems enables flexibility and ensures smooth data exchange between various parts of an organization.

6. Security and Compliance: OIC provides robust security features, including encryption, identity management, and compliance with industry standards. This helps in maintaining the integrity and confidentiality of data.

7. Real-time and Batch Processing: It supports both real-time and batch processing, accommodating different integration needs.

8. Monitoring and Analytics: Through its detailed monitoring and analytics capabilities, OIC provides insights into integration performance, errors, and usage statistics, enabling proactive management and optimization.

9. Scalability: The cloud-native architecture ensures that OIC can scale to meet the demands of large and complex integration scenarios.

10. AI-Enabled Recommendations: Some versions of OIC include artificial intelligence (AI) capabilities that can provide recommendations and insights to assist developers in building more efficient integrations.

11. Event-Driven Architecture (EDA): OIC supports event-driven integrations, enabling real-time responsiveness to specific events or changes within applications or systems.

12. Collaboration Tools: It provides collaboration tools to enable teams to work together effectively on integration projects.

13. Serverless Computing: OIC allows for serverless computing, meaning you don’t need to manage underlying infrastructure, enabling a focus on developing integration rather than managing servers.

14. Adapters for Various Technologies: OIC offers a wide array of adapters to facilitate integration with various technologies like databases, file systems, RESTful web services, and more.
