Research And Implementation Of Automatic Generated UML Activity Diagram Technique

As users demand growth and demand for the addition of new features,makes software systems become more complex.Software development organizations in their efforts to address these needs,often in a continuing inability to deal with the dilemma of changing user needs.Based on the definition of use case model of the demand for ways to overcome these problems,can make the demand for rapid conversion to the system design level. Similarly,the use case can also be reused,so that the entire software life cycle becomes more rapid.Therefore,use case modeling will have an impact on the "software factory" in the field of model-driven software engineering progress.Were greatly enhanced by the development team and stakeholders the ability to communicate between,and enabled us to more easily determine more accurately the demand.Use-case driven approach is the current international epidemic,one of the software development process,all phases of software development activities are at the core use cases.In addition to its own research, but also extensive and in-depth into various fields of software engineering,such as requirements capture,system development,system testing,model-driven software engineering and so on.This paper describes the use-case driven demand in the capture of superiority,as well as the model for the conversion of technical studies,the major use case modeling will be automatically converted to UML activity diagram of the automatic conversion of technology to conduct in-depth analysis and research,and try to convert technology applied to.NET Framework from the realization of the development framework.In system design and realization of the process,use case and activity diagram of the automatic conversion between the MES system and process control needs of practical application to make a useful combination of exploration and research.
