Analysis And Design Of Guiyang Swiss Source Yutong Technology Development Co., Ltd. Security Equipment Sales Management System

Aiming at guiyang ruiyuan yutong technology development co., LTD., the existing security equipment sales management system has been unable to cope with profit growth in the amount of information, and as the increasing of the determinants of participation in decision-making greatly improve equipment management complexity, this paper studies the characteristics of security equipment sales management, the purpose is based on the existing equipment management system, the use of database technology, analysis and design a set of suitable for yutong technology security equipment sales management system.This article is based on the object-oriented development method introduces the project summary of background and problems in the system, and the research significance and importance in detail, and expounds the main work and thesis research content. Secondly, in this paper, the system development method, modeling techniques and tools as well as the related database technology are described. Then in this paper the demand analysis of system in detail, including business requirements analysis, functional requirements analysis, data demand analysis and the analysis of the non-functional requirements. Business requirements analysis on the system of business process activity diagram are given; Function requirement analysis of system use case diagram is given, and the detailed use cases; It gives the concept of system in data requirements analysis class diagram and class diagram of the thumbnail, said demand mainly from the environment in the non-functional requirements analysis, performance requirements and safety requirements. Again, in the design of the system, the system overall design and function module design, mainly include the purchase management, sales management, inventory management and system management module. On function module design of system function structure is given package diagram, class diagram, activity diagram, sequence diagram and processing in detail to design the contents of this paper. On the database design, mainly using entity class diagram, e-r diagram and the database table structure to carry out the detailed design. At last, the paper summarized the content of the research, my main work is expounded, the shortage of the paper are pointed out, and the further work were also discussed.
