Structured Analysis and Design Technique

The Structured Analysis and Design Technique (SADT) is a methodology for software development published by Douglas T. Ross in 1977. A descendant of this is IDEF. SADT basic element

The basic element of the modeling is the function, represented as a rectangle, which transforms the input variables (input, arrows from the left) into the output variables (English, output, arrows to the right). Mechanisms (arrows from below), for example resources, are required for execution. Other influences or disturbances (control) are shown as arrows from above.

Multiple functions can be executed one after the other in which an output of the one function is connected to the input of the other.

The step-by-step modeling can be done top-down. A function is decomposed hierarchically, i. a function of a level, is represented in the next level as the interconnection of several subfunctions. Single-level Edit source text Weblinks Edit sourcetext
