Emphasizing component reusability (DRY principle), Django offers out-of-the-box features like a login system, database connectivity, and CRUD operations (Create Read Update Delete). Operational Mechanism of Django: Django adheres to the MVT design pattern (Model View Template). Model: Represents data, typically sourced from a database. Django employs Object-Relational Mapping (ORM), simplifying database interaction. Unlike SQL, which necessitates database knowledge, ORM allows streamlined communication without intricate SQL coding.
