What is Apache Airflow?

</aside>

Airflow is an orchestration tool. Apache Airflow is a tool for managing and automating workflows. It helps you schedule, organize, and monitor tasks like data processing or file transfers.

What is Workflow? (Workflow / Pipeline)

</aside>

A workflow is a series of steps or tasks that need to be completed to achieve a goal. In Apache Airflow, workflows are called DAGs (Directed Acyclic Graphs).

For example:

1. Extract data from a database.
2. Process or clean the data.
3. Load the data into a report or another system.

Each step is a task, and the order of tasks defines the workflow. Workflows ensure tasks happen in the correct sequence.

What is DAG?

</aside>

A DAG (Directed Acyclic Graph) is the structure Airflow uses to define workflows.

Key points:

• Directed: Tasks have a specific order (e.g., Task A → Task B).
