摘 要
今天我们生活在充满数字的时代，随着GPRS、CDMA1X、蓝牙、WLAN等无线技术的突飞猛进，移动生活、移动办公逐渐由概念转为现实，信息数据随手可及。特别是广域无线数据传输技术的成熟，运营商的大力推广，WLAN的应用日渐普及，逐步渗透到金融、公安、教育、物流、商贸等行业中，并日益影响到人们生活的方方面面，种种梦想化为现实成为了可能。对于传统的餐饮业而言，也在潜移默化中感受到无线网络的无穷魅力。
通常情况，餐厅点餐、送单、结账都采用人工传递，这种工作流程效率低下，而且在就餐高峰期人员繁杂的情况下，服务员在快速手写点餐、人工送单中可能还会增加误操作的几率，造成客人投诉，影响到服务质量，甚至有损餐厅的美誉度。随着WLAN技术的普及，一些规模较大的酒楼餐厅开始考虑利用这种最为先进、最具时尚潮流的网络技术来建设一套灵活、快捷的信息管理系统，以优化管理流程，使酒店的服务和管理得到实质性的提升，提高品牌形象和行业核心竞争力。
本设计主要讲述了点餐系统的基本功能和数据库的设计方法。设计最终达成了包括用户登录，点菜管理功能模块，点菜管理功能模块、并台管理功能模块、转台管理功能模块、查台管理功能模块、结台管理功能模块、更新管理功能模块、注销功能模块、设置功能模块等。
并且系统能够正常运行，各个界面交互性较好。在系统规划中先后用数据流程图，系统功能结构图分析了系统所需的各种数据，详细的展示了系统的各个功能模块，并给出了主要功能运用界面图。

Wireless Ordering System Design And Implementation
Abstract
Today we live in full digital era, as GPRS, CDMA1X, bluetooth wireless technology of WLAN, etc by leaps and bounds, mobile, mobile office by concept into reality, gradually information and data conveniently. Especially the wide-area wireless data transmission technology maturity, operators of promoting the growing popularity of WLAN, application, permeate education, public security and finance, logistics, commercial, and other industries, and increasingly affect all aspects of people's lives, all sorts of dream a reality. For the traditional industry, also in imperceptible felt a wireless network infinite glamour.
Usually, a restaurant meal, single, using artificial transmission, check the work flow, and low efficiency in the miscellaneous meal peak personnel circumstance, waiter in quick meal, artificial send handwritten may increase the chances of wrong operation, guest complaints, affect the service quality, reputation or detrimental to restaurant. With the popularization of WLAN technology, some large restaurant dining began to consider using the most advanced, the most fashionable tide of network technology to build a flexible and convenient information management system, to optimize the management process, make hotel service and management, increase substantially brand image and core competitiveness.
This design is mainly about the basic function of the Order management system and database design method. Design eventually reached include user login, order management function module, order management function modules, and Taiwan management function module, the turntable management function module, check stage management function module, \management function module and update management function module, cancellation function module, function module, etc
And the system can run normally, each interface interaction is good. In systems with planning, system function structure of data flow analysis system for the detailed data shows that the system function module, and presents main function using interface diagram.
