摘 要 随着市场竞争的加剧，企业需要更加快捷便利的管理方式。对销售型企业来讲，需要对其进货渠道、库存以及销售进行管理。随着业务量的不断增加，利用电脑软件对产品销售进行管理可以为企业提供方便、快捷、准确的数据，企业产品销售分析类软件在企业产品销售过程中逐步得到重视。 本系统着手于研究一个适用于超市类销售企业而开发的较为实用的产品销售分析软件。在该系统中，包括：处理产品保质期而设计的功能模块，处理入库和销售的定单模块，以及处理用户的管理等模块。在销售数据报表中，提供多种报表查看方式，可以按产品提供商为组查看库存状况，能清晰得到企业的产品销量，为后续产品销售提供参考。系统以订单为单位对销售进行管理，便于追踪每一个产品。系统在结构上采用了三层架构，视图层负责显示页面，业务逻辑层负责数据的运算而数据访问层负责数据库的存储和访问。 本系统在管理产品销售的同时，也注重研究对销售的数据进行统计分析，将销售的原始数据进行加工，能够根据目前的销售状况提出决策建议，帮助企业不断改善经营策略，在竞争中获得优势。 关键词：.NET框架； 销售预测； 数据分析；产品销售； Abstract Companies need more convenient and efficient management in face of fiercer market competitions. With ever-increasing business volumes, it is necessary for sales companies to better manage their purchase, storage and marketing. More and more companies are turning to sales analysis software during the process of marketing of their products as they can have easier and faster access to accurate data by using computer software in sales management.

The software is composed of several units, including a service module that handles product warranty, a supply module that keeps track of items sold and items in stock as well as a customer management module. The software can generate various report forms based on sales data, e.g. you can check on storage of an item according to its supplier so as to replenish stock of items that are selling well. It’s easy to trace each product as the system manages sales by indexing orders. The system has adopted a three-tier structure: the presentation tier displays the pages, the logic tier processing the data and while the data tier reads and writes the database. In addition to management of product sales, the system provides predictions on stocks based on statistical analysis of the sales data, thus, helping companies maintain their competitive edge with better business strate
