Design And Implementation Of "Small And Medium Enterprises Invoicing Management System

Of the large number of small and medium-sized enterprises at present in China, there are many types of goods, it is difficult to manage, and mostly using artificial management, low efficiency, easy to mistake. In addition, due to the variety of data, data processing workload is very tedious and easy to make mistakes, and also easily lost and not easy to find. In short, there is badly in need of effective formal means of information management. In order to make up for the above shortcomings, the enterprises decide to develop the R & D Invoicing management system. This is a use of advanced computer technology and development, set the purchase, sale, storage, statistics, query and other links in one information system. The goods management standardization, systematization, program, improve the speed and accuracy of information processing.In the system development process, we mainly uses the component technology, C/S mode, the database system theory, which is used in the system application component amount, improve the system’s maintainability and scalability, but also greatly shorten the system development cycle, the SQL based Server 2000 data base, the implementation of the system development using Delphi7.0 a detailed description of the platform, his participation in the specific code design function module. And the system is a series of tests, the results show that: the system is stable, the correct results, achieved the desired design target of the project.This thesis mainly analyze from the small and medium-sized enterprise Invoicing management system development background, development situation at home and abroad, and the research purpose and content about, the system focuses on the related theory and technology, the requirement analysis, design, implementation and testing; demand analysis part of the feasibility, system requirements, system functional requirements, the main business case analysis are analyzed to describe; design part of the system design and implementation of the constraint, the overall structure of the system function, function design and database design; implementation part describes the realization of interface and program code of main modules in the system. In this thesis, the maximum in the design process to meet customer demand, has strong practical and targeted. The Invoicing management system is for the domestic small and medium-sized enterprises, can complete the function: basic information management, for all goods, suppliers and customer data can realize the input, modify, delete, query; purchase management, to manage the list and purchase return management; sales management, can management of sales orders and sales return, inventory management, can clearly see the quantity, inventory of products stored location information, can storage, and inventory management; query statistics, can quickly query, commodity, with customers suppliers, sales, sales returns, storage, warehousing, sales ranking and other information, and timely reporting; system management, can change the password, data backup, restore, see the log, but also for employees with different level of permissions settings, improve system security.
