Structured Analysis and Design Technique (SADT)

What is Structured Analysis and Design Technique (SADT)?

Structured Analysis and Design Technique (SADT) is a method of systems analysis and design that is based on the use of graphical models and symbols to represent the various components and processes of a system. SADT is designed to be a systematic and organized approach to systems analysis and design, and is based on the concept of decomposing a system into smaller, more manageable pieces that can be analyzed and designed separately.

In SADT, the system being analyzed is represented using a hierarchy of models, each of which represents a different level of detail and abstraction. The top level of the hierarchy represents the system as a whole, while the lower levels represent increasingly detailed and specific aspects of the system.

SADT is often used in the development of software systems, as it provides a structured and systematic approach to defining and modeling the various components and processes of the system. It can also be used in the analysis and design of other types of systems, such as business processes or manufacturing systems.
