Construction on Data Flow Diagram and Data Dictionary of Chinese Online Examination System

Abstract:

Chinese plays an important role in human life, so Chinese online examination system must be developed in the light of shortcomings of the traditional Chinese examinations. Data flow diagram and data dictionary in this paper are the basic work of developing Chinese online examination system and lay the foundation for requirement analysis. A hierarchical data flow diagram was built in the data flow diagram, and the top-level data flow diagram consists of two things: the system name and two external entities that are teacher and student, and one-layer data flow diagram was divided into teacher subsystem and student subsystem data flow diagram according to subsystem; extracted one from each category entries in the data dictionary, and teachers (external entities), papers information (data stream), papers generation (processing), submission information tables (data storage) were described namely.
