Explain

Mendix uses a visual modeling environment to define UI, data models, and logic.

Microflows and nanoflows allow declarative logic design for backend and frontend processes.

It supports multi-channel apps: web, native mobile, and hybrid.

Integration with REST, SOAP, databases, and enterprise systems is built-in.

Deployment can target Mendix Cloud, private cloud, or on-premise environments with CI/CD support.
