【正文】 I 摘 要 中國(guó)是舉世聞名的美食大國(guó)，擁有五千年的飲食文化和巨大的餐飲市場(chǎng)。隨著人民生活水平和生活方式的轉(zhuǎn)變，漸漸的人們發(fā)現(xiàn)餐飲業(yè)具有巨大的投資市場(chǎng)。中國(guó)市場(chǎng)的競(jìng)爭(zhēng)尤為激烈，而且隨著餐飲業(yè)的迅速擴(kuò)展，其中所暴露的問(wèn)題也是不容忽視的 ，如 餐飲業(yè) 管理 人才的專業(yè)化程度不夠?qū)е聝?nèi)供不足 ， 餐廳 缺少 一套現(xiàn)代企業(yè)制度和監(jiān)督管理體制， 服務(wù)管理 應(yīng)變能力差，缺乏先進(jìn)的信息工具 等。 所以 ， 餐飲業(yè) 管理 從觀念意識(shí)、經(jīng)營(yíng)思想和管理水平還有待專業(yè)化。 因此，開發(fā) 實(shí)用型點(diǎn)菜系統(tǒng)是餐飲業(yè)發(fā)展的必然趨勢(shì)。 本系統(tǒng)是基于 Linux 系統(tǒng)下開發(fā)的餐廳點(diǎn)菜系 統(tǒng)，運(yùn)用服務(wù)器 /客戶端開發(fā)模式，采用的是 RedHat 企業(yè)版 5，圖形界面功能由 QT 類開發(fā)，后臺(tái)數(shù)據(jù)庫(kù)采用 SQLITE3，網(wǎng)絡(luò)編程使用的協(xié)議是 Linux 支配的 Socket TCP/IP 協(xié)議。前臺(tái)劃分為前臺(tái)管理，點(diǎn)菜管理，后廚管理，數(shù)據(jù)庫(kù)管理，服務(wù)器五個(gè)功能模塊。 本系統(tǒng)的主要作業(yè)流程，從顧客在前臺(tái)查看餐桌空閑空閑狀態(tài)，入桌點(diǎn)菜，可以加菜、刪菜等，提交菜單，后廚按照菜單做菜，顧客到前臺(tái)結(jié)賬，前臺(tái)打印賬單，顧客結(jié)賬，實(shí)現(xiàn)了開臺(tái)、點(diǎn)菜、加菜、刪菜等系統(tǒng)設(shè)計(jì)功能。 關(guān)鍵詞： 餐廳點(diǎn)菜系統(tǒng)； Linux； QT； SQLITE3 II Abstract China is worldfamous cate big country, with five thousand years of diet culture and great food market. As the people39。s living standard and life transitions, gradually people found restaurant industry has great investment market. China was particularly intense market petition, 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, work 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 system39。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.
