摘 要
中国是举世闻名的美食大国，拥有五千年的饮食文化和巨大的餐饮市场。随着人民生活水平和生活方式的转变，渐渐的人们发现餐饮业具有巨大的投资市场。中国市场的竞争尤为激烈，而且随着餐饮业的迅速扩展，其中所暴露的问题也是不容忽视的，如餐饮业管理人才的专业化程度不够导致内供不足，餐厅缺少一套现代企业制度和监督管理体制，服务管理应变能力差，缺乏先进的信息工具等。所以，餐饮业管理从观念意识、经营思想和管理水平还有待专业化。因此，开发实用型点菜系统是餐饮业发展的必然趋势。
本系统是基于Linux系统下开发的餐厅点菜系统，运用服务器/客户端开发模式，采用的是RedHat企业版5，图形界面功能由QT类开发，后台数据库采用SQLITE3，网络编程使用的协议是Linux支配的Socket TCP/IP 协议。前台划分为前台管理，点菜管理，后厨管理，数据库管理，服务器五个功能模块。
本系统的主要作业流程，从顾客在前台查看餐桌空闲空闲状态，入桌点菜，可以加菜、删菜等，提交菜单，后厨按照菜单做菜，顾客到前台结账，前台打印账单，顾客结账，实现了开台、点菜、加菜、删菜等系统设计功能。

Abstract
China is world-famous cate big country, with five thousand years of diet culture and great food market. As the people's living standard and life transitions, gradually people found restaurant industry has great investment market. China was particularly intense market competition, and with the rapid expansion of catering industry, which is exposed to the problem is also not allow to ignore, such as catering management personnel of professional enough to lead to internal for shortage, lack of a restaurant modern enterprise system and supervision and management system, service management strain ability is poor, lack of advanced information tools etc. So, catering management from the idea consciousness, management thought and management level remains to be professional. Therefore, the development of practical order system is an inevitable trend in the development of catering industry.
This system is based on Linux system of development order system restaurant, using server/client development mode, use is RedHat enterprise version 5, graphic interface functions by QT kind of development, the backend database using SQLITE3, network programming use agreement is Linux dominate Socket of the TCP/IP protocol. The front desk is divided into the front desk management, order management, management after hutch, database management, server five function module.
The system's main operation process, from the customer in the front desk check table free idle state, into the table to order, can add food, delete vegetables etc, submit the menu, kitchen according to menu after cooking, the customer to front desk check, front desk print bill, customer checkout, realize the founding, order, and food, delete vegetables etc system design functions.
Keywords：Restaurant order system；Linux；QT；SQLITE3
