| With the development of computer information technology and software development, more and more strict with every stage of the software life cycle.Software requirements is key to the success or failure of the system development, so the demand of management, became a hot research.Demand is difficult to control in the development of demand changes, also often leads to the failure of the entire software development.This system is the core task is reasonable and effective management of requirement changes, changes to the request, assign, analysis, risk assessment, confirmation and implementation of control, and the changes in demand around the requirements baseline, change control, could obtain the hierarchy of business requirements, user requirements and functional requirements, and requirements traceability chain is formed.Demand management software for this article first discusses in some of the background and research status at home and abroad, then analyses the system development of related technology, finally in detail elaborated the system analysis and system implementation process.In this paper, the main work is as follows:(1) the system USES mature c # programming language and SQL 2008 database development technology, puts forward the technical scheme development system, and satisfy the demand of management software technical feasibility, with scalability, ease of use and stability.(2) analysis of the demand management software requirements, design the system function, system management, project management and the functions of the demand management.(3) the use of UML modeling analysis demand function of management software, through the use case diagram, activity diagram, sequence diagram and the ER chart system model is constructed.Demand management software by using the computer website to manage the demand information greatly convenient for software management and development personnel, improve the working efficiency, reduces the associated costs. |
