摘要:本设计是围绕食品企业的进销存管理的业务展开分析与设计的，针对现今企业这样的一个业务现状，我们采用的是结构化的软件开发方法进行系统的开发，整个过程可以分为系统调查，系统分析、系统设计以及系统实施这样的几个阶段。该系统是以企业的进货管理业务、退货管理业务、销售管理业务、以及库存管理业务为核心的。在整个系统的分析与设计的过程中，始终采用的是结构化方法。该方法要求本系统的开发的整个过程始终要按照规定步骤，要配合相应的图表工具，在结构化和模块化这样的基础之上进行开发。在设计的过程中，系统的分析和总体设计阶段，采用的是“自上而下”的方法，而在系统的详细设计阶段所采用的则是相反的“自下而上”的方法。该设计的方案基本上可以满足新系统对业务的需求，具有一定的实用性。

　　　正是为了适应了数字化的潮流，针对企业的进销存管理做出的这样一个系统，目的是提高企业的工作效率，增强企业的竞争能力，更好的迎合社会发展，大大节省了人力资源并简化了工作流程。经过我的慎重考虑，将ASP.NET作为系统的开发平台的首选，配合使用C#语法进行开发，主要是利用其提供的各种强大开发工具，首先应该在短时间内建立系统的应用原形，然后，对建立的原形系统进行需求迭代，不断的进行修正和加强，直到最后形成用户满意的可行系统，基本上能够实现产品的进销存管理所需的全部功能。 

　　　本文详细的介绍了系统开发的全过程。本系统采用生命周期法这样的软件工程的设计思想进行全程开发，包括系统分析、系统设计、系统测试等。

Abstract:This design is about food enterprises Invoicing management to analyze and design business, according to the business situation of enterprises, using the software development method of structured system investigation, system analysis, system design and system. The system is based on the purchase management, the enterprise returns management, sales management, and inventory management as the core. In the process of analysis and design of the whole system, we use the structured method. The method requires the development of this system has been in accordance with the provisions of procedure, with a certain graph tool, in a structured and modular basis. In the process of design, the system analysis and overall design stage, using the "top-down" approach, and for the detailed design stage of information systems is the "bottom-up" approach. Basically can satisfy the system requirements for the design, has a certain practicality.

　　　It is adapted to the digital trend, a system for Invoicing management of the enterprise, the purpose is to improve the efficiency of enterprises, and better meet the social development, save human resources and simplified the work process. After analysis, we use ASP.NET as the development platform of the system, using the C# syntax development, use the various object-oriented development tools, first established in a short time system application prototype, then, for the initial prototype system needs iteration, and constantly revised and improved, until forms the user satisfied feasible system, all the basic functions the marketing and product management.

　　　This paper introduces the system development process. According to the software engineering design ideas, using of the whole life cycle of method development, including system analysis, system design, system testing and so on.
