Design And Implementation Of Medium Enterprises Purchase-Sales-Inventory Management System

Commodity inventory management system is an important part of product information systems,as well as the normal operation of the enterprise network marketing indispensable part.Currently,the invoicing system software is facing low quality,which cannot effectively meet the development of enterprises.The goal of this paper is to design a high efficiency,low cost invoicing goods management system to directly help the companies on operating and economic efficiency.By completing all aspects of requirements,system functions have been analyzed.Combining with the system management module and communication components,the user privileges have been considered corresponding.The system address stable technology to meet practical requirements.Design and implementation purchase-sales-inventory management system,which can improve the quality and efficiency of software design.In summing up the basics of CMMI,based on a detailed description of the goals and practices CMMI risk management.From the development feasibility,use cases,requirements functional requirements,business processes and CMMI tracking matrix five aspects of the system carried out a detailed needs analysis,in-depth study of the corporate procurement management,functional sales management,inventory management,business logic and systems and non-functional requirements,clarify the design ideas.At the same time risk management in CMMI-based,increasing the risk of tracking process,making the software project risk management more systematic and complete.Then,the overall system design of the overall function of the system is divided.Then,at the design stage through CMMI tracking matrix of the system designed to monitor,grasp the system design progress and quality of design and detailed design of the line.On the basis of the system design,implementation and testing system to complete the function.The system development is reflected in the characteristics and advantages:Based CMMI project monitoring and control improvements,making the whole process of software project monitoring and process control formation of the corresponding specifications,software final quality,schedule and cost to achieve the desired standards.Ease of implementation and good scalability.
