Q. Explain the Structured Design of system?
Structured Design utilizes graphic description (Output of system analysis) and focuses on development of software specifications. The objective of structured design is to lead to development of programs comprising functionally independent modules which perform relatively independently of each other. It is a specific program design scheme, not a comprehensive design method. So it doesn't specify database or file design, input or output layout or the hardware on that application will run. It offers specification of program modules which are functionally independent. It is a process-centred technique which transforms structured analysis models in good software design models. Structured Design introduced a modeling tool known as Structure Charts. They are used to explain software (program) structure to fulfil business requirements. Structure charts define the interaction between independent module and data flowing between the modules. These module specifications can be passed to programmers before the writing of program code. In structure chart whole application is divided into modules (set of program instructions) and modules are designed according to some principles of design.
