The transitive reduction consists of the edges that form length-one paths that are the only paths connecting their endpoints. This is also known as a topological ordering of a graph. In this representation, data enters a processing element through its incoming edges and leaves the element through its outgoing edges.

A directed acyclic graph means that the graph is not cyclic, or that it is impossible to start at one point in the graph and traverse the entire graph. Other applications include scheduling, circuit design and Bayesian networks.

Provided that pairs of events have a purely causal relationship, that is edges represent The converse is also true. DAGs can model many different kinds of information.
The lack of a cycle follows because the time associated with a vertex always increases as you follow any Sometimes events are not associated with a specific physical time.
Dag is an Australian and New Zealand slang term, also daggy (adjective) and dagging (verb, to behave in a daggy way). The edges of the directed graph only go one way. DAGs leverage the concept of incremental deployment, which is the ability to deploy service and data availability for all Mailbox servers and databases after Exchange is installed.After you deploy Exchange Server Mailbox servers, you can create a DAG, add Mailbox servers to the DAG, and then replicate mailbox databases between the DAG members. In computer science and mathematics, a directed acyclic graph (DAG) is a graph that is directed and without cycles connecting the other edges.

For instance, in electronic circuit design, static Graphs in which vertices represent events occurring at a definite time, and where the edges are always point from the early time vertex to a late time vertex of the edge, are necessarily directed and acyclic. For example, it is possible to find Directed acyclic graphs representations of partial orderings have many applications in For instance, when one cell of a A somewhat different DAG-based formulation of scheduling constraints is used by the A directed acyclic graph may be used to represent a network of processing elements. For example, a Every directed acyclic graph has a The family of topological orderings of a DAG is the same as the family of These numbers may be computed by the It is also possible to check whether a given directed graph is a DAG in linear time, either by attempting to find a topological ordering and then testing for each edge whether the resulting ordering is validAny undirected graph may be made into a DAG by choosing a Any directed graph may be made into a DAG by removing a The transitive closure of a given DAG, with In all of these transitive closure algorithms, it is possible to distinguish pairs of vertices that are reachable by at least one path of length two or more from pairs that can only be connected by a length-one path.
That is in any application represented by a directed acyclic graph there is a causal structure, either an explicit order or time in the example or an order which can be derived from graph structure.
