In the paper, we analyze the shortages of service-oriented analysis and design (SOAD) methodologies, and then review the features of data flow diagram as a kind of requirement analysis technology.

Existing software used to drawing the process flow diagrams (such as AutoCAD or Visio) does not have recognition and analysis function. For the images output by software, this paper describes the ...

In computing, algorithms are needed to design computer programs. is a logical, step-by-step process for solving a problem. Algorithm production is part of algorithmic thinking, an important ...
