Software Requirement Analysis Research Based on Event-Driven

This paper proposed a kind of software requirements analysis technology method based on event-driven. In structured analysis method, system relation diagram, DFD fragments and 0-level figure are developed through the establishment of events table. Further DFD diagram decomposition is carried on to obtain the analytical model. We can divide the subsystem through events and external entities interaction, data storage interaction and common point analysis in processing requirements. Regarding the object-oriented method, use case diagram and sequence diagram are developed based on the events. Presented two analysis methods in the analysis technology and realized the analysis in detail. Through the case analysis, briefly introduces how to use the method to carry on structured analysis and complete software requirement modeling. The result shows that the method is easy and feasible.
