Message Routing	Explore how messages are routed to different endpoints.
Message Transformation	Explore how messages are transformed into different formats.
Data Integration	Explore how data from various sources are used during message mediation.
File Processing	Explore how data from file systems are moved and used during message mediation.
SaaS and B2B Connectivity	Explore how to integrate with third-party systems using WSO2 connectors.
Service Orchestration	Explore how multiple Restful services are exposed as a single course-grained service.
Enterprise Messaging	Explore asynchronous messaging patterns using message brokers.
Scheduled Integration Processes	Explore how integration processes are scheduled and executed periodically.
Protocol Switching	Explore how message protocols are changed during message mediation.
