摘  要

二十一世纪，网络化、信息化等名词已经成为当下时代的标签，且随着Internet的飞速发展，网络应用日益广泛，互联网已经成为当今社会一个非常热门的研究领域，如：电子商务，网络教学，网络游戏，网上医疗等。

本文首先分析市场上已存在订餐系统的实际需求和业务流程，再结合顾客的习惯消费方式，设计并实现了一个实用的农家乐网站。具体研究内容包括以下几个方面：首先，本文在讨论网上订餐市场趋势和市场优势的基础上，分析系统的功能需求和非功能性需求，并对系统需求以用例图和用例描述的形式进行详细说明。其次，在需求分析基础上，根据系统需求提出系统设计目标和原则，分别设计了系统技术架构和功能架构。其中，技术架构主要考虑系统的可扩展性、可维护性以及性能问题，采用分层模型的J2EE架构，设计和分析了各层的功能；而功能架构设计主要讨论了系统各部分的功能组成，并给出一个动态的系统功能流程。再次，在系统架构设计的基础上我们进行了农家乐网站的详细设计。该部分按订餐用户、农家乐用户和系统管理员用户三个模块来设计系统，并对各个模块的设计进行了描述。在系统建模中，给出了农家乐网站的整体结构图，进而分别讨论了订餐用户、农家乐用户和系统管理员用户各个模块的详细设计。最后，本文对农家乐网站的应用情况作了简单介绍，并对系统进一步改进提出了建议。

综上所述，我们在分析业务需求和分析顾客的习惯消费方式的基础上，采用了SSH整合框架技术，设计并实现了农家乐网站。

ABSTRACT

    In the 21st century, informatization has become the contemporary label. With the rapid development of Internet and the increasingly wide range of network applications, Internet has become nowadays a very popular research fields, such as electronic commerce, network teaching, online games, online medical and so on.

In this paper, we design and implement a practical online meal ordering system  by analyzing some existing meal ordering systems and the actual needs of the business process, and combining the habits of customers. Specifically, we first will discuss the functional and non-functional requirements of the system based on the market trends and advantages. Then we present a detailed description of the system requirements by some case diagrams and descriptions. Secondly, according to the function analysis, we propose the design goals and principles of this system, and the technical and functional frameworks of this system. Among them, for the technical framework the scalability, maintainability and performance of this system are studied. We analyze and design the function of each layer by using the J2EE architecture of the layered model. For the function of architecture design, we mainly discuss the functionality of each model of the system, and give a dynamic system process. Thirdly, we show a detailed design of online meal ordering system based on the above analysis. In the whole system, there are three modules including customers, restaurant owners and system administrators. We describe the overall structure of the online meal ordering system. Moreover, the detailed designs of three modules are described. Finally, we conclude the whole system and propose some suggestions for the further improvements.

In summary, we apply Struts, Spring, Hibernate framework technology to design and realize an online meal ordering system on the basis of analyzing the business needs and the customer's consumption patterns
