A DAG (Directed Acyclic Graph) is the core concept of Airflow, collecting Tasks together, organized with dependencies and relationships to say how they should run. It defines four Tasks - A, B, C, and D - and dictates the order in which they have to run, and which tasks depend on what others. In addition to using traditional operators, Airflow has introduced the TaskFlow API, which makes it easier to define DAGs and tasks using decorators and native Python code. Rather than explicitly using XComs to share data between tasks, the TaskFlow API abstracts away this logic, instead using XComs behind the scenes.
