DAG (Directed Acyclic Graph)

A Directed Acyclic Graph (DAG) is a type of data structure used in computer science and mathematics that consists of nodes connected by directed edges, where each edge has a direction indicating a one-way relationship. The term "acyclic" means that there are no loops or cycles, so you can’t return to a node by following the edges. DAGs are useful for representing processes where certain tasks depend on previous ones, such as project scheduling or organizing data in blockchain technology. This structure helps to efficiently manage and visualize relationships and dependencies in complex systems.
