Research And Application Of Agile Modeling And Flexible System Design

Today,with the frequent changes in software development requirements,agile modeling is becoming more and more popular among software developers.However,as development costs and maintenance costs increase,the abstract guidance of the senese of value and principle in agile modeling can not effectively save development costs in details and efficiency to advance the development process.The details of the practice in agile modeling depend on the management and development experience of the development team.Agile modeling is an engineering practice process for incremental development and rapid iteration.Increment and iteration are its two main features,but for how to increment and iterate,agile modeling itself does not provide guidance.Unscientific incremental iterations are the main cause of software activity failure,and may also cause confusion in software system design,laying a hidden danger for future software maintenance.The flexible system design idea is discussed from the organizational structure of the system,and the software system is designed scientifically and effectively to ensure the flexibility of the software system.This paper attempts to introduce the idea of flexible system design in agile modeling.While ensuring development agility,by optimizing the software organization structure and periodic incremental iteration,the software development is more agile and the software system is more flexible.This paper first elaborates on the agile modeling theory,introduces the application scenarios and characteristics of agile modeling,the tools and the methods,and proposes the incremental iteration problem that may exist in agile modeling.Aiming at this problem,this paper expounds the advantages of flexible system,and analyzes the possibility of introducing flexible system in agile modeling,and introduces a series of flexible system construction methods,including object-oriented method and dynamic design and refactoring methods,component structuring methods,workflow methods.At the same time,this paper studies the agile modeling cycle and introduces flexible factors to study.Finally,this paper demonstrates the feasibility and effectiveness of the agile flexible modeling method in the J province title management system,and provides guidance for the specific practice of the agile flexible modeling method.
