What types of integration have you worked with? Which ones do you know?

In the practice of a systems analyst, various types of integrations are encountered:

• API integration — data exchange via REST, SOAP, GraphQL, and other protocols.
• File exchange integration — CSV, XML, JSON files transferred via FTP, SFTP, or cloud storage.
• Database-level integration — direct access to databases, replication, use of ETL processes.
• Data bus integration (ESB) — using Enterprise Service Bus for message routing and transformation.
• Message queue integration — RabbitMQ, Kafka, and other systems for asynchronous communication.
• Middleware and broker integration — software layers that facilitate communication between systems.

Familiar with projects where REST API was used for data exchange between web applications, as well as using ETL processes for loading data from external sources into analytical systems.
