What are the main components involved in the data exchange structure between systems?

The main components of data exchange structures between systems include:

• Data format — defines how data is structured (e.g., JSON, XML, CSV).
• Transfer protocol — rules and methods for data transmission (HTTP, TCP/IP, MQTT, etc.).
• Data schema — description of data structure and types for validation and interpretation.
• Serialization/deserialization mechanisms — converting data to a format for transmission and back.
• Identification and authentication — ensuring security and access control.

For example, when exchanging data via REST API, data is usually transmitted in JSON format over the HTTP protocol, where the schema describes the structure of JSON objects.
