Design And Implementation Book Sales Invoicing System

With the times progress, the IT popularizing,more and more commercial retail enterprise information management systems are increasingly being widely used. Due to the small and medium sized entities bookstore shortage of funds, the basic information is weak, uneven quality of personnel and other conditions, resulting in inefficient operations management, Prone to operating errors, the lack of real-time analysis functions. Compared with the manual management of small and medium sized bookstores,For small- and medium-sized bookstore for information management with a high efficiency, low error rate, ease of management and many other advantages, especially in the book sales, inventory, purchasing and other functions became more integrated inventory management software is currently needed for these bookstores. Although currently there are a lot of related software, but because each bookstore has its own unique business management model, and therefore a common inventory management software is not applicable, and the development of a targeted management system will be very important.The author from the bookstore ’s daily sales and inventory management services to the bookstore business processes conducted a detailed investigation, in different roles from the bookstore clerk, purchasing personnel, warehouse manager and other business needs for different starting conduct a needs analysis, the spirit of improving bookstore management efficiency, cost savings, convenient operation ideas, In detail elaborated the development front desk bookstore book sales Invoicing system, running processes and related technical specifications.This paper aims to design a suitable medium and small entities bookstore inventory management system and uses an object-oriented approach to design. System development process: first for enterprise field surveys, analysis of the functional requirements of the system which then recognition system use cases and actors, analyze the system use case diagram, and then gradually refine the use case diagram for each module, and then completed a data flow diagram and data dictionary specific design; system design stage completed a major division of function modules, the detailed design of the database, system interface design about the man-machine dialogue and Specific code design. The system includes several important part of the reception module sales, inventory management module, statistical analysis module, library management module, membership management module, information maintenance module. The system specific function can be achieved login, change password, future sales, inventory management, library management, membership management, supplier management, user management roles, sales statistics and analysis functions. Different users who use this system are given different permissions, all query results can be printed out in the form of a report, for easy access.
