- 2. INTRODUCTION Django uses the Model-View-Controller (MVC) pattern, with slight variations, primarily following the Model-Template-View (MTV) pattern. This structure enhances developer productivity and maintainability. Models represent the data layer, View handles presentation logic, and Controller coordinates interactions. MTV maintains data-related tasks, while Views serve as Controllers, promoting maintainable code and modularity in Django web applications. the data layer, View handles presentation logic, and Controller coordinates interactions.

DJANGO ARCHITECTURE COMPONENTS • Django's Model is the data layer, encapsulating application structure, ensuring integrity, and handling database interaction, defined as Python classes inheriting from django.db.models.Model. • Django's Views are Python functions that handle incoming requests, data retrieval, and rendering, encapsulating application logic and handling business logic, determining data display and user response. • Django templates, like the View component in MVC, generate the application's presentation layer, containing HTML markup, embedded tags, and filters, dynamically rendering data and sending output to the client's web browser.
