Small And Medium Enterprises Design And Implementation Of Invoicing Management System

Invoicing management for small and medium enterprises is an important part of an enterprise business management. It is the key part whether the enterprise can gain. Invoicing management system in the enterprise management merges management science and computer technology. The system can make enterprise procurement, inventory and sales all naturally combine together. The combincation of logistics, capital flow and information flow greatly improves the productivity and benefit of enterprises.This system adopts the method of object-oriented analysis and design to complete the construction of the whole system.In specific written on paper, at first, this paper briefly introduces the origin and meaning enters sells saves the management system, analyzes the advantages and disadvantages of the existing system, and adopts C/S mode is presented, using vc + + as the system development language, SQL 2005 as the system’s database system solutions;In the systematic analysis of the requirements phase, according to the actual needs of enterprise management to the invoicing system, complete the function of the system requirements of the business, and identification system of the participants and the use cases, use UML to build the associated use case diagram of the whole system, and analyzes some important cases;In carries on the system design phase, determine the system USES the MVC architecture pattern, and according to the functional requirements and use case diagram, class diagram and system static structure model was established for dynamic structure model sequence diagram and state machine diagram, static modeling and dynamic modeling through detailed description of the operation of the entire system in invoicing system, at the same time to realize the concept design and physical design of database;In the final stages of system implementation, and use of vc + + engine control three layer separation, views, models, at the same time using ADO database access technology to achieve the database connection.System architecture, the function mainly realizes the basic information management, commodity procurement, warehousing, sales statistics, and several important function modules of the query.Through the above the realization of function module, effectively solve the traditional manual management enters sells saves the mode with low efficiency, easy to cause errors, and many other problems, to the development of enterprises play an important role in promoting.At present, the research designed by small and medium-sized enterprise enters sells saves the management system has been successfully implemented, and has carried on the detailed test validation.Function test and performance test results show that the system fully meets the requirements of all user expectations, complete implementation of all functions, but also meet the initial requirements of various performance indicators.To sum up, this system has realized the small and medium-sized enterprise enters sells saves the management work of electronic, can greatly improve the efficiency of enterprise enters sells saves the business processing, as well as the efficiency of management staff.The development of enterprises has important application value.
