A directed acyclic graph is a directed graph that has no cycles. [1] [2] [3] A vertex v of a directed graph is said to be reachable from another vertex u when there exists a path that starts at u and ends at v. As a special case, every vertex is considered to be reachable from itself (by a path with zero edges).
Every time you run a DAG, you are creating a new instance of that DAG which Airflow calls a DAG Run. DAG Runs can run in parallel for the same DAG, and each has a defined data interval, which identifies the period of data the tasks should operate on.

Nov 8, 2023 · Introduction to Directed Acyclic Graph. Last Updated : 08 Nov, 2023. A Directed Acyclic Graph, often abbreviated as DAG, is a fundamental concept in graph theory. DAGs are used to show how things are related or depend on each other in a clear and organized way.
Jul 5, 2024 · A DAG is a Directed Acyclic Graph, a type of graph whose nodes are directionally related to each other and don’t form a directional closed loop. In the practice of analytics engineering, DAGs are often used to visually represent the relationships between your data models.
Jul 17, 2017 · A DAG is a Directed Acyclic Graph — a conceptual representation of a series of activities, or, in other words, a mathematical abstraction of a data pipeline. Although used in different circles, both terms, DAG and data pipeline, represent an almost identical mechanism.

The term DAG stands for Directed Acyclic Graph. A DAG is a mathematical concept, technically, a blockchain is the most simple form of a DAG.
A causal diagram, or causal ‘directed acyclic graph’ (DAG), is a cognitive tool that can help you identify and avoid, or at least understand and acknowledge, some potential sources of bias that might alter your study’s findings.
