**Dependency graph**— In mathematics, computer science and digital electronics, a dependency graph is a directed graph representing dependencies of several objects towards each other. It is possible to derive an evaluation order or the absence of an evaluation order… …42

**Dependency (project management)**— This article is about project management dependency. For other uses, see Dependency (disambiguation). In a project network, a dependency is a link amongst a project s terminal elements. There are four kinds of dependencies with respect to… …43

**Dependency Structure Matrix**— A Dependency Structure Matrix, or DSM (also referred to as Dependency Structure Method, Design Structure Matrix, Problem Solving Matrix (PSM), incidence matrix, N square matrix or Design Precedence Matrix), is a compact, matrix representation of… …44

**Dependency diagram**— A dependency diagram is a visual representation of a dependency graph. Dependency diagrams are integral to software development, outlining the complex, interrelationships of various functional elements. Typically in a dependency diagram, arrows… …45

**Dependency Ratio**— A measure showing the number of dependents (aged 0 14 and over the age of 65) to the total population (aged 15 64). Also referred to as the total dependency ratio . Calculated by: This indicator gives insight into the amount of people of non… …46

**dependency theory**— A set of theories which maintained that the failure of Third World states to achieve adequate and sustainable levels of development resulted from their dependence on the advanced capitalist world. Dependency theories developed in opposition to… …47

**Dependency need**— A dependency need is characterized by two components: (1) It is a real need of the organism, something that must be present for the human being to thrive, (2) It is something that individuals cannot provide for themselves. An infant has very many …48

**Dependency relation**— In mathematics and computer science, a dependency relation is a binary relation that is finite, symmetric, and reflexive; i.e. a finite tolerance relation. That is, it is a finite set of ordered pairs D, such that If then (symmetric) If a is an… …49

**dependency ratio**— A simple indicator of the age composition of the population which typically varies in the range 0.5 to 1.00. Early definitions of the dependency ratio refer to the total number of young dependants divided by the total number of persons of… …50

**Dependency Inversion Principle**— Das Dependency Inversion Principle (DIP; dt. Abhängigkeits Invertierungs Prinzip ) ist ein Prinzip beim Objektorientierten Entwurf von Software. Es beschäftigt sich mit der Abhängigkeit von Modulen. Strukturierung von Modulen nach DIP Im… …
