商品销售管理系统设计论 文毕业设计 II 内容摘要 在科学技术日新月异的今天，计算机已逐步渗入各个领域，无论是学习， 工作，还是娱乐都普及了计算机的使用，而随着网络的开通、并与 Internet 连 接更让我们社会成为信息化的时代，人们不再需要浪费太多的时间去手工的获 得信息，只要做在家中轻点几下鼠标不但能轻松获得各种信息，而且能够购买 到自己需要的商品，既摆脱了时间和空间的限制又节约了大量的时间，因此熟 练使用计算机及网络，已成为人们进入现代社会的必备技能。商品销售管理系 统正是在这种情况下诞生并逐渐发展起来的，它已成为我们进行商品交易中不 可缺少的部分。 商品信息管理系统是典型的信息管理系统(MIS),其开发主要包括后台数据 库的建立和维护以及应用程序的开发两个方面。对于前者要求建立起数据一致 性和完整性强、数据安全性好的数据库，而对于后者则要求应用程序功能完备, 操作简单等。 本系统是在分析了现行商品管理中存在的问题的基础上，结合信息管理系 统开发的概念、结构及系统开发的基本原理和方法，开发的一套商品信息管理 系统。根据实际情况，由目前各功能需求和公司里的情况而设计的这套系统。 全文共分为课题研究的意义、开发环境、系统的实现、性能测试与分析以及结 束语等章节，详细地阐述了本系统开发的目的、过程。 关键词：信息管理系统；系统开发 ；商品销售 Abstract The rapid advance of science and technology today, the computer has gradually infiltrated all areas, regardless of learning, work, or entertainment throughout all of the computers use, and with the opening of networks, connecting with the Internet and made us become information-based society of the times, People no longer need to waste too much time for manual access to information. As long as it is at home Click on the mouse and understand world, but to buy their needs of commodities, both out of time and space constraints to save a great deal of time, the use of skilled computer and network, People have become modern social skills required. Sales Management System is under such circumstances birth and gradually develops and it has become a commodity transactions indispensable part. Commodity information management system is typical of the Information Management System (MIS), including development of its key database background to the establishment and maintenance of front-end applications and the development of the two areas. Regarding the former requirement to establish data consistency and integrity of strong, good data security database. As for the latter demanded the application functions, and simple operation. The system is the analysis of the existing merchandise management problems that exist on the basis of a combination of information management systems development concepts, structure and system development and the fundamental principles and methods, developed a set of commodity information management system. According to the IV actual situation from the various functional needs and the situation of the company and the design of such systems.
