Describe structured analysis and structured design.

Answer:

 

Structured analysis:

Structured analysis is a software engineering technique that uses graphical diagrams to develop and portray system specifications that are easily understood by users. These diagrams describe the steps that need to occur and the data required to meet the design function of a particular software. The structured analysis technique is based on the following underlying principles:

  • Top-down approach
  • Application of divide and conquer principle
  • Graphical representation of the analysis results using DFDs.

Structured design:

The aim of structured design is to transform the results of the structured analysis into a structure chart. A structure chart represents the software architecture. The structure chart representation can be easily implemented using some programming language. The various modules making up the system are the module dependency and the parameters that are passed among the different modules.
