Django web application architecture separates concerns across presentation, application, and data layers using Views for request handling, Models for ORM database abstraction, and Templates for HTML rendering. User requests flow from the web browser through Views, which orchestrate data retrieval via Models and response formatting through Templates, then return rendered HTML back to the client. PostgreSQL serves as the persistent data store, accessed exclusively through Django's ORM layer to enforce data integrity and security. This three-tier pattern demonstrates Django's MTV (Model-Template-View) architecture, a best practice for maintainable, scalable web applications.
