The Construction of Improved Data Structure in Computer Software Development and Research of Contribution under Mechanism Analysis

In this article, studied the computer software development through the mechanism analysis method, and established improved data structure diagrams. It affirmed the importance of demand analysis in the software development process. First, introduced the concept of mechanism analysis, computer software development and demand analysis. Secondly, comprehensive evaluation was used for studying the several graphical tools in the process of requirements analysis. Screening of the most beneficial method of data analysis, which were data flow diagrams and structure of language. Finally, we gained the improved data structure which combined with the two ways of data flow diagrams and structured language to describe the data stream of complex problems.
