【正文】 t System, which is the use of information technology means to bring advanced enterprise management methods into business practice for enterprises to enhance the management level to provide a practical way. Hankook Tire Company, taking into account their business in recent years, the gradual expansion of the daily flow of data within enterprises has also increased the amount, if you still simple to use manual operation, not only the process cumbersome, heavy workload, but also easily lead to inconsistencies in the data or loss of data. System to a mon enterprise purchasing, sales and inventory of such mercial activities as well as basic information related to customer management. The system is divided into six functional modules, which are: purchasing management function modules, function modules sales management, inventory management function module, basic information management function module, financial management function modules and systems management functional blocks. The system is based on B / S architecture design, using the popular Java technology development, background data is stored using SQL Server 2021 database to store data. Based on the current development of technical specifications, the program structure is divided into three levels, namely: presentation layer, logic layer and persistence layer. Presentation layer used in Struts2 framework implementation, business logic tier using Spring framework of the implementation, use of Hibernate persistence framework to achieve. This paper describes in detail Invoicing system development process, from initial feasibility studies to software testing have given a detailed description. After several demonstration and testing, ultimately reached in this graduation project design requirements.
