8、各種各樣的菜品，確保每天的工作效率和身心健康，這些問題就產(chǎn)生了快捷訂餐的需求，實現(xiàn)這種式莫過于利用網(wǎng)絡，將餐飲業(yè)和網(wǎng)絡結合起來，就形成最快的方式-網(wǎng)上訂餐，這種方式能足不出戶，輕松方便地實現(xiàn)自己訂購餐飲和食品（包括飯、菜、飲料等）。有能力的餐飲企業(yè)可以對菜品、飲料等提供商提供網(wǎng)上訂餐服務，不僅提高餐飲企業(yè)的服務質(zhì)量，對于擴大知名度，和提升市場競爭力有很大的益處。隨著人民生活質(zhì)量要求的不斷提高，餐飲業(yè)及它在服務行業(yè)中的地位也越來越重要，如何從激烈的競爭中獨樹一幟，已經(jīng)成為每位餐飲老板所要思考的問題。經(jīng)過多年的發(fā)展，對餐飲企業(yè)的管理經(jīng)營已經(jīng)逐漸的由簡單的人為管理，進入到規(guī)范的利用科學手段進行管理。

9、在科學管理的具體實現(xiàn)方式和方法中，最有效率的工具就是應用餐飲管理軟件進行管理。將應用軟件用于現(xiàn)代的餐飲業(yè)，解決了傳統(tǒng)的筆上記賬，統(tǒng)計，對于核算方式計費等費時費力的難題，這種方式既容易操作，又不會出錯誤，提高了餐飲業(yè)管理水平。第一章 項目概述1.1 現(xiàn)狀概述科學技術在不斷發(fā)展，計算網(wǎng)絡機通信行業(yè)讓人們?nèi)藗兊臏贤ㄔ絹碓奖憬?，使今天的社會進入了以計算機為核心的社會，網(wǎng)絡通信的出現(xiàn)給我們諸多方面帶來了無限的商機與便利（比方說餐飲業(yè)）；計算機與網(wǎng)絡的普及也使人們對web的設計和外觀要求越來越嚴格，完美而動感的畫面給人們更好的視覺感受,因此，網(wǎng)站作為一個企業(yè)的代表需要精心設計。餐飲業(yè)經(jīng)營者也就可以利用自己

10、的網(wǎng)站，發(fā)布酒店的信息和菜品信息，每種菜都有精美的圖片，這樣可以實現(xiàn)酒店或餐館的自我推薦，從而吸引網(wǎng)民的關注。能夠很方便的預定需要的菜品及飲品。足不出戶就可以享受上等的佳肴，網(wǎng)上訂餐為客戶提供的是最方便的飲食方式，以最快、最便捷的訂餐服務，并且有自己的類似與肯德基的宅急送，送貨上門為客戶服務，這省去了客戶很多不必要的時間和麻煩，給經(jīng)營者帶來更多利益，同時，網(wǎng)上訂餐可以增加社會的就業(yè)率。通過信息管理成的方式，可以記錄餐飲企業(yè)各方面的數(shù)據(jù)和信息。與過去的的電話訂餐相比，網(wǎng)絡訂餐有著很多的優(yōu)點。例如如：顧客通過電話訂餐時，往往由于本身對餐飲企業(yè)提供的信息不太了解，就會進行不必要的咨詢，導致時間上的浪

11、費。電話接收人員在同一時間反復重復相同的信息，也造成了人力的浪費。相對而言，網(wǎng)絡訂餐提供圖片及文字介紹，豐富而詳實的信息讓客戶就像在超市里挑選商品一樣點擊添加自己喜愛的餐品，這在一定程度上滿足了客戶的自由選擇權是購買商品能夠更加的愜意。通過網(wǎng)上訂餐系統(tǒng)也將訂餐推廣到更加廣泛的群體當中，使得訂餐增多，飯店的知名度提高。網(wǎng)絡不會同電話一樣占線，在高峰期對訂餐的處理更是綽綽有余，很少會出現(xiàn)向系統(tǒng)崩潰的現(xiàn)象，而且網(wǎng)上訂餐的費用不會想電話訂餐那樣高，相比之下有自己的競爭力。同時兩者有事相輔相成的關系，可以擴大客流量，提升餐飲行業(yè)的業(yè)務量無論如何網(wǎng)上訂餐終將成為一種時尚一種潮流，將使傳統(tǒng)的餐飲更加具有勃勃

12、生機，在眾多行業(yè)中立于不敗之地。1.2 系統(tǒng)業(yè)務流程經(jīng)過前期調(diào)研分析和綜合其它各方面相關理論知識，現(xiàn)歸納網(wǎng)上訂餐系統(tǒng)的業(yè)務流程如下：1 .用戶進入登錄頁面后，可以選擇是否注冊個人信息，如果選擇注冊，即可進入注冊信息界面，注冊個人信息，成為會員；如果選擇不注冊，則可進入非會員通道。2. 用戶注冊后，如果忘記密碼，可以找回個人密碼。3. 用戶成功登錄后，即可進入訂餐頁面，首頁顯示的是今日特價菜，用戶可以訂購特價菜，也可以選擇其他菜式進行訂購。4. 用戶選好菜式后，可將其加入購物車，完成訂單。5. 用戶可以對自己選購的或者未選購的菜品進行評價，可以增加其他用戶對菜式的了解。6. 管理員在后臺數(shù)據(jù)庫進

13、行菜品的添加加，修改和刪除，同時還可設定今日特價菜。同時管理員也對會員進行管理。根據(jù)以上總結出來的業(yè)務流程，結合在學校學習到的java web知識，經(jīng)過對需求調(diào)研的總結，給出網(wǎng)上訂餐系統(tǒng)的業(yè)務流程圖。業(yè)務流程圖用于描述現(xiàn)系統(tǒng)各項業(yè)務處理過程，并結合業(yè)務流程圖詳細、詳實地說明業(yè)務處理過程中數(shù)據(jù)的采集、輸入、提交、存儲、加工的方法及算法、輸出的數(shù)量及形式等。業(yè)務流程圖的圖例如表1.1，網(wǎng)上訂餐系統(tǒng)業(yè)務流程圖如下圖1.1所示：表1.1業(yè)務流程圖圖例符號名稱說明處理可以改變數(shù)據(jù)的值或建工組件輸入輸出數(shù)據(jù)的輸入與輸出人員使用程序的人或系統(tǒng)數(shù)據(jù)流指明數(shù)據(jù)流動方向賬冊、報表用于記錄數(shù)據(jù)的紙質(zhì)文檔網(wǎng)上訂餐系統(tǒng)

14、的開發(fā)主要圍繞以上的業(yè)務流程進行，開發(fā)過程采用面向?qū)ο蟮木幊趟枷爰笆褂胘ava開發(fā)語言，詳細的開發(fā)過程見如下章節(jié)。圖1.1 網(wǎng)上訂餐系統(tǒng)業(yè)務流程圖第二章 系統(tǒng)需求分析2.1 需求陳述為了開發(fā)出真正滿足用戶需求，軟件產(chǎn)品首先必須進行需求分析。對軟件需求分析和了解是軟件開發(fā)成功的關鍵，不論項目人員把設計和編碼工作做得多么的出色，不能真正滿足用戶需求的程序只會令用戶失望，從而不斷地修改軟件給開發(fā)者帶來煩惱。需求陳述為以下工作提供了良好的機制；了解客戶需要什么，分析需求求，估計可行性，討論決定合理的方案，無歧義的詳細說明方案，確認規(guī)格說明，管理需求最終將這些需求轉化為可運行的軟件系統(tǒng)。根據(jù)調(diào)研分析得知

15、，網(wǎng)上訂餐系統(tǒng)共需要完成4項中心任務，即：用戶信息管理、菜單信息管理、菜品評論管理、訂單管理。每項任務具體描述如下：1.用戶信息管理用戶的注冊信息管理模塊主要由后臺管理人員負責，用戶注冊成功后，信息由后臺管理人員管理，管理人員根據(jù)用戶是否已經(jīng)注冊，確定其是否為會員，方便用戶管理。會員制是平臺應該具備的。通過會員制，不僅可以為顧客訂餐提供方便，還可以保持顧客積累量。顧客在登陸系統(tǒng)首頁后，可以在用戶注冊界面點擊注冊按鈕，頁面便跳轉到用戶注冊頁面，用戶在填寫完密碼，確認密碼，聯(lián)系電話，保留信息等資料后點擊提交便可完成注冊。用戶還可以點擊重置按鈕來清除已填寫的自己想改的信息，方便用戶在想重新填寫注冊資

16、料時使用。2.菜單信息管理菜單信息管理模塊主要由管理人員來操作，主要負責對增添新菜品、修改菜品信息、刪除菜品、設置特色菜進行管理。方便用戶進行菜品的訂購。3.菜品評論管理菜品評論管理主要是用戶可以對菜品進行評論，方便其他用戶對菜品的了解。4.訂單管理訂單管理主要是指用戶訂餐后，確定其訂購后，將菜品加入購物車中，產(chǎn)生訂單，方便用戶了解自己的菜品訂購。同時方便管理人員對用戶訂購菜品的管理。系統(tǒng)確認之后，接下來的工作就是進行系統(tǒng)的分析。系統(tǒng)分析主要是包括面向?qū)ο蠓治?，分析問題域等，畢竟我們采用的是面向?qū)ο蟮拈_發(fā)語言，如何設置對象，建立對象之間及對象和外度系統(tǒng)之間的關系，建立起必要的對象關系模型，如設

17、置對象中的屬性方法，使他能夠更精確的表示事物的客觀屬性，為系統(tǒng)分析提供假設條件。2.2 USE CASE建模2.2.1 定義參與者參與者(actor)是指與系統(tǒng)無關的、需要利用與系統(tǒng)交互的東西，包括人、設備、外部系統(tǒng)等。根據(jù)網(wǎng)上訂餐系統(tǒng)的需求可以確定2個參與者，即：管理員主要維護用戶基本信息管理，菜單信息管理，訂單管理，以及菜品評論信息管理。用戶主要的功能是注冊個人信息，登錄，找回密碼，訂購菜品，以及進行菜品評論。2.2.2 Use Case圖用例圖定義：由用例（Use Case）、參與者（Actor）和它們之間的關聯(lián)所組成的用于描述系統(tǒng)功能的動態(tài)視圖稱為用例圖。用例圖（User Case）是

18、被稱為參與者的外部用戶所能觀察到的系統(tǒng)功能的模型圖，呈現(xiàn)了一些參與者和一些用例，以及它們之間的關系，主要用于對系統(tǒng)、子系統(tǒng)或類的功能行為進行建模。用例圖展示了用例之間以及同用例參與者之間是怎樣相互聯(lián)系的。用例圖用于對系統(tǒng)、子系統(tǒng)或類的行為進行可視化，使用戶能夠理解如何使用這些元素，并使開發(fā)者能夠?qū)崿F(xiàn)這些元素 您好，為你提供優(yōu)秀的畢業(yè)論文參考資料，請您刪除以下內(nèi)容，O(_)O謝謝！A national survey was recently launched to evaluate the eye

33、ogging after a whole day's work can be a way to unwind. It is true for He Wenjun, whose workplace is right near the forest park. She discovered her athletic aptitude at the age of seven, when she began playing tennis. Then she turned to jogging, and she has persevered with it for 10 years. "

34、;I come to jog almost every day after work, whenever I have time. I think jogging is good for my health. And for me, a girl, it helps me to achieve to eternal goal, to keep slim," He said. He says she prefers jogging alone, so she can focus better. She loves jogging, even during Beijing's s

35、moggy days. "If the smog is severe, I'll hold off jogging for a while. But if I really want to get away from work, I'll wear a mask, or just ignore the smog and go on jogging," she said. For those who are not so athletic, jogging also has its attractions. Wu Houbin started roughly

36、two years ago, when he was severely obese. Within two months, his weight dropped from 82 kilograms to 64 kilograms. The success helped him recover health, and he has made friends. "Jogging does not require speed, but stamina. If you want to stick to the game, you need to take it as a mission, a

37、 habit, and then eventually a hobby," Wu said. But persevering with jogging is not always easy. Jogging is beneficial for heart-lung function, and the skeletal system, but doctors say improper technique damages the joints, especially the knees and ankles. "Excessive jogging wears down the

38、body, and harms one's health. Poor technique harms the muscles and skeleton, and can cause secondary injures. And, jogging in a bad environment can cause circulation problems," said Lu Zhiyong, attending doctor, Sports Hospital, General Admin. of Sports.Dr. Lu has some tips for joggers, and

39、 those who are thinking of taking it up.He says people should first evaluate their physical condition, to decide the amount and type of exercise, and jogging in the open air is better running on a treadmill. Conrad Macao will run special programs for the entire month of October this year to support

40、the Hong Kong Cancer Fund's Pink Revolution, an annual campaign that seeks to raise awareness and funds for breast cancer research, the hotel recently announced. A major sponsor of the campaign for three years in a row, Conrad Macao has pledged to donate a portion of its proceeds to the fund, in

In addition, on Fridays that month, members of the management and staff will add something pink to their uni

42、forms, regular e-mails and handwritten guest cards. "Breast cancer is the most prevalent type of cancer among women in Hong Kong and is also of significant concern in Macao and around the world, regardless of age," general manager Bede Barry said in a statement. The hotel has enlisted the

43、support of a number of international and local celebrities to help drive the cause, including South Korean actor Jung Suk Won. This year, a lucky guest who stays at the hotel during the campaign and also donates money for the cause will win a necklace specially designed by Arte Madrid, a Spanish jew

Xiao Ying, 36, works for a large law firm. Her job means lots of travel, a heavy caseload and a large number of meetings, so her schedule

45、 is hectic. She has been pregnant twice, but had abortions on both occasions because she felt her busy, high-pressure career wasn't conducive to raising a child. She planned to have children once she had achieved career success so she could provide a stable environment for her baby. After 10 yea

46、rs, Xiao felt the time was right, and she tried to conceive for about six months, but was unable to become pregnant. I conducted comprehensive physical checkups. The results suggested that Xiao's ovarian function has declined and a bilateral oviduct blockage has occurred, meaning that in vitro f

47、ertilization is her only option. So, after reducing her workload, Xiao underwent IVF treatment. Luckily, she got pregnant after just one treatment cycle, but later experienced vaginal bleeding, and rushed to the hospital. I told her to rest and carry on with the treatment (to prevent a miscarriage).

48、 As Zubin Zarthoshtimanesh, a yoga guru, demonstrated postures at a high school stadium in Dujiangyan city, Sichuan province, some 200 students sat on colorful mats watching him closely. It was part of the first India-China international yoga festival in the provincial capital, Chengdu, in Southwest

49、 China, where more than 1,000 fans from home and abroad gathered for lessons from 20 leading practitioners of the ancient Indian regimen, from June 17-21. Yoga is to India what perhaps tai chi is to China. Many countries other than India and China, also held the first World Yoga Day on June 21, afte

50、r the United Nations last year agreed to Indian Prime Minister Narendra Modi's suggestion that a special day be marked in the year for the global practice of the stress-busting regimen, which is already a multibillion dollar industry in the United States. Modi said in the speech: "Yoga is a

51、n invaluable gift of India's ancient tradition. . It is not about exercise but to discover the sense of oneness with yourself, the world and nature."Zarthoshtimanesh, who runs his own yoga center, Iyengar Yogabhyasa, in the Indian financial capital of Mumbai, says: "Chinese students ar

This, the worlds longest glass-bottomed walkway, is located in Shiniuzhai Geopark in Hunan, and spans 300m (984f) and is 180m (590f) above ground

54、. The floor is made of double-layered glass that is 24mm (0.94in), and is reportedly 25 times stronger than regular window glass. The bridge had previously been made of wood, linking the two peaks of Stone Buddha Mountain, but 11 engineers working 12 hours a day converted it to glass. Previously, yo

56、ts.At the age of 37, Shanghai native Lin Zhengu has become a star as a Western cuisine chef in the Chinese metropolis, a city that has a wealth of Western restaurants. The executive chef of Blue Frog Bar and Grill, a popular burger-based restaurant and bar chain on the Chinese mainland, Lin is the s

57、oul of the restaurant franchise's team of more than 550 chefs. Many of the franchise's most popular dishes are his brainchild. Lin says his secret of success is innovation rooted in experience: He spends months every year traveling and eating worldwide, seeking new ingredients and inspiratio

58、ns that could improve the offerings of Blue Frog restaurants. The restaurant chain regularly launches a new seasonal menu, usually featuring eight new dishes with fresh ingredients. The best-selling seasonal dishes later replace the least popular items on the regular menu, which is usually updated i

59、n late fall and boasts a selection of about 40 dishes. "Food should have no boundaries," Lin says. "As long as the food tastes good and is healthy, it doesn't really matter where it originates or how it is cooked." Lin likes to give the American-style restaurants' menu so

60、me culinary touches from other countries, such as China and Mexico, and customers love such innovation, he says. He started his career as an apprentice in a Chinese kitchen in 1993. By chance he learned from a French chef in 1994, and soon became enamored with the world of Western food. During the n

61、ext couple of years, he received strict training in Western culinary art from French, Chinese and German chefs. That was rare for a Chinese chef in the 1990s, he saysand so was being a Chinese chef who spoke fluent English. When an American entrepreneur invited him to join in his startup Blue Frog i

62、n 2000, Lin didn't hesitate to resign from a five-star hotel to work in the new restaurant with just five chefs, eager to explore the excitement of a life that had yet to unfold. Since that Shanghai launch, Blue Frog has opened 24 branches in seven cities across China, including Beijing, Tianjin

63、, Chongqing and Nanjing in Jiangsu province. The new menu for this fall, which was launched in early September, showcases how flavors of East and West meet to create a variety of delicious burgers and other entrees in the cozy, soft-lit restaurants. I liked the mapo burger best. Just imagine the flavorful combination of the hot, mildly numb-spicy mapo tofu sauce and grilled 100-percent Australian beef patty, along with a slice of cheddar cheese and a side of french fries. The sav
