Function tree

A function tree is a diagram describing the function of the features of a system with one another. One could also say, a function tree shows how a problem (or a problem solution) into sub-problems (or partial solutions ) can disassemble. From the perspective of an implementation of a computer program, this means that this diagram shows the function calls that other functions.

Function trees are commonly used to illustrate the functional dependencies of operations, for example in the economy or society. Even in software engineering can be employed, where there accurate representation forms are preferred, as they are defined, for example, of the Unified Modeling Language.

Function trees can also serve as a starting point for sequencing or parallel (→ graph partitioning ).
