Knowra Dependency graph Dependency graph A directed graph in which vertices represent components and edges represent dependencies between them. It can reveal ordering constraints, shared prerequisites, and dependency cycles.
Directed graph : A graph whose edges have orientations from one vertex to another. Dependency edges point from a component to a prerequisite, or in the reverse convention.
Build system : Software that automates compiling, linking, and packaging programs and their dependencies. Build systems use dependency relations to decide which targets to rebuild and in what order.
Graph theory : The mathematical study of graphs and their properties. Dependency graphs apply graph-theoretic ideas to relations among components.
Prerequisite graph : A directed graph whose edges represent prerequisite relations among courses, tasks, or steps. It is a domain-specific dependency graph, commonly used to plan course sequences.
Topological sorting : A linear ordering of a directed acyclic graph's vertices in which every edge points forward. It turns an acyclic dependency graph into a valid execution or build order.
Package manager : Software that installs, upgrades, configures, and removes software packages. Package managers resolve package dependencies before installation.
Adjacency list : A graph representation that stores, for each vertex, its neighboring vertices. It is a common way to store each component's direct dependencies.
Call graph : A graph representing which functions or procedures may call which others. Call edges describe possible control flow, not necessarily prerequisite availability.
Directed acyclic graph : A directed graph containing no directed cycles. Acyclic dependency graphs admit a topological ordering of their components.
Task scheduling : The assignment of tasks to times or resources subject to constraints. A dependency graph specifies precedence constraints among scheduled tasks.
