網(wǎng)上建材銷售系統(tǒng)畢業(yè)設(shè)計開題報告

1、v1.0可編輯可修改連海工摩院畢業(yè)設(shè)計（論文）開題報告理工類題基于 ASP的網(wǎng)上建材銷售系統(tǒng)的設(shè)計目：與實現(xiàn)學(xué) 院：計算機工程學(xué)院專業(yè)班級：計算機科學(xué)與技術(shù) D計061班學(xué)生姓名： 黃 剛 學(xué)號：09指導(dǎo)教師： 巫曉琳（講師）2010年1 月9 日淮海工學(xué)院畢業(yè)設(shè)計（論文）開題報告1 .課題研究的意義，國內(nèi)外研究現(xiàn)狀、水平和發(fā)展趨勢”一番菠于苕天!拓和賴亞而雨i而曩而匚''示下美麗前及“ 向了網(wǎng)購。對網(wǎng)購者來說，只需鼠標(biāo)輕輕一點，即可完成購買。雖然同樣是上網(wǎng)點點鼠標(biāo)，但途徑還是有所區(qū)別的。記者調(diào)查發(fā) 現(xiàn)，目前大致有三條上網(wǎng)購買建材的通路。第一條通路是建材大超市開設(shè)的網(wǎng)上商城。

2、這些建材超市已經(jīng)以 實體店的形態(tài)存在多時，有規(guī)范的進貨渠道，有嚴(yán)格的驗貨制度，有 專業(yè)的導(dǎo)購人員，是三條網(wǎng)購?fù)緩街凶顬榘踩?，但這樣的網(wǎng)上商城 很少。據(jù)了解，很多建材超市只在網(wǎng)站上提供部分商品的展示和促銷 信息，并不能進行網(wǎng)上購物，真正開通網(wǎng)購的建材超市非常少，因此, 消費者選擇的余地也非常小。止匕外，消費者還要承擔(dān)貨物延期、訂單無法執(zhí)行的風(fēng)險。因為這 些建材超市將主要的精力投入在實體店上，網(wǎng)上商城則每天最多僅同 步一次庫存信息，庫存信息無法得到及時更新，而消費者在網(wǎng)上購買 的商品又在門店同時銷售，因此可能出現(xiàn)其他顧客買走了剩余商品的 情況，造成臨時斷貨或者不再進貨的可能，這時，到貨期就會相應(yīng)

3、延 長，甚至出現(xiàn)訂單無法執(zhí)行的情況。在支付方式上，這些網(wǎng)上商城也不能完全做到貨到付款。消費者 一般需要先支付一定數(shù)量的定金或者全額付款。第二條途徑是以電子商務(wù)為背景的網(wǎng)上建材超市， 擁有數(shù)萬款商 品，并且通過網(wǎng)站上的專業(yè)分類，再配合以搜索功能，可以幫助消費者在海量產(chǎn)品中輕松找到需要的商品。 網(wǎng)上設(shè)有即時溝通平臺，隨時 答疑。這些電子商務(wù)網(wǎng)站的更新速度很快，一般也開設(shè)有“第三方支 付”的金融服務(wù)，交易比較安全，但是，這些網(wǎng)站是近年來才紅火起 來的，他們雖然精于網(wǎng)絡(luò)技術(shù)，但對建材這一傳統(tǒng)商品卻尚稱不上十 分專業(yè)，而建材這類商品又是非常龐雜非常需要有專業(yè)的進貨經(jīng)驗 的。第三條途徑是一些個人在類似淘寶

4、網(wǎng)這樣的“ c to c”網(wǎng)站上開 設(shè)的網(wǎng)絡(luò)小店，產(chǎn)品不可能十分齊全，一般專做某類產(chǎn)品，或者干脆 做宜家等一些品牌店的專業(yè)代購。大家都知道信息勝似黃金！但是在這個信息爆炸的年代，網(wǎng)絡(luò)上 充斥各種各樣的信息，其中有真有假，有好有次。這往往使從商者無 所適從。本網(wǎng)站會提供專業(yè)準(zhǔn)確的信息，還會幫助分析各方面的綜合 因素。本網(wǎng)站會為各位商人提供交流的平臺， 切實的反應(yīng)建材市場的現(xiàn) 狀，讓商人根據(jù)具體的信息作出自己準(zhǔn)確的商業(yè)判斷。-23 -淮海工學(xué)院畢業(yè)設(shè)計(論文)開題報告2 .課題的基本內(nèi)容，可能遇到的困難，提出解決問題的方法和措施本網(wǎng)站是借鑒其他網(wǎng)站設(shè)計的，IDE環(huán)境用的是 Visual Studi

NET mobile controls 1 (formerly known as MMIT, short for theMicrosoft Mobile Internet Toolkit) for example, it reduces the work required for developers to

At runtime, MMIT will automatically detect the target device and return the proper presentation format. Thus, the developers can focus on the application logic without worrying about the presentation is

25、sues.Similar academic researches on this topic include 2 and 3. Both of them provide plug-ins for famous IDEs, such as JBuilder and Visual respectively, to assist developers to author a single generic application. Accompanied with the PUML transformation technology 4, this generic application can be

26、 further transformed into specific target formats for different mobile devices.MotivationWidespread of mobile devices makes it common to browse Web pages via them. However, most Web pages are mainly designed for desktop computers that are equipped with big screens. When browsing on mobile devices, a

27、 user might have to scroll up and down, left and right all the time to find the information they want. Because of the limited screen size, this kind of operation is really not user-friendly at all.Fortunately, somefamous websites have another simplified version of Web content specially provided for

28、mobile devices, such as Google Mobile 5 and Yahoo Mobile 6. On the other hand, it is a heavy burden on Web developers to craft and maintain multiple versions of the same website. Even with the help of the fascinating toolkits.If weresize the original Web page to fit the width of mobile device, the v

29、ertical scroll bar will be too long to view, and the information is crowded. On the other hand, if we provide another version of the original Web page, there may be some important information lost in the mobile version, and the transformation of each page costs a lot for Web page developers. Hence,

30、in this research, we propose a system that is designed to help users to personalize their mobile Web pages for handheld device browsing.Research objectivesIn this sub-section, the four major research objectives are listed and introduced briefly.Easy-to-useIt does not makesense to launch another prog

Parts of them are used to maintain a consistent style f

33、or the website, and other parts of them are used for navigation. Some renowned websites may even contain a lot of advertisements on it. In many Web pages, only a few of information is really needed to be shown on the mobile phone screen. This research also aims at allowing a user to determine which

34、parts of a Web page should be retained while browsing this page with their mobile device.A friendly user interface should thus be available for a user to perform this task. For example, with appropriate visual aids (such as highlight), a user can choose blocks in a Web page one by one with different

35、 granularity.Through the operation of drag-and-drop,a user candetermine the relativeposition of the chosen blocks according to his/herpersonal preferences. In short, a user can reconstruct a mobile Web page simply with visual manipulations, and does not have to write any line of code.According to th

A cross-browser configuration tool is designed.2. The web -based nature of our configuration tool allows a user to configure the setti

41、ngs from different computers, and requires no pre-installation of any software.3. Blocks in a Web page can be chosen correctly under the premise that the layout of a Web page does not change frequently.4. A web -based management interface is provided.5.

In Section 2, an overview of the proposed system and its three major components are given. In Section3, the System design details, problems encounte

43、red, and our corresponding solutions are 川ustrated. Furthermore, we discuss our mobile Web page generation algorithm in Section 4. In Section 5, sometests are conducted to evaluate our system. A practical example showing how to make use of the proposed tool to eliminate unnecessary scrolling is also

44、 presented.Several related works are discussed in Section 6. Finally, in Section 7, we make the conclusion and discuss about the future work.2. System design .Overview Basically, the personalizing process in our Web page tailoring system comprises two steps (Fig. 1). First, user must specify his/her

45、 preferences of a Web page using a PC or laptop. Second, he/she has to configure the browser on his/her mobile device to go through a specially madeproxy, which is responsible for adjusting the content of Web pages according to the preferences set in the first step. Twopictures are given below to il

46、lustrate separately the relationship between a user, our Web page tailoring system, and a remote Web server (such as in each step.Fig. 2 describes the interaction in the first step. Whena user enters a URL in his/her Web browser, a HTTP request is sent to (Line 1) the corresponding Web server specif

47、ied in the URL. After processing the request by the server, a HTTPresponse is sent back (Line 1). If the user wants to personalize that page, a program hosted on a tiny Web server included in our system would be downloaded (Line 2) and executed in his/her browser. With the help of that program, the

48、user can specify his/her preferences simply by visual manipulations. After finishing the job, preferences about this page will be sent back and stored in a database for later use (Line 2).Fig. 2. Personalize Web pages using PC or laptop.Fig. 3 pictures the interaction in the second step. Since the u

49、ser would configure the browser on his/her mobile device to use a proxy included in our system, we would snoop each HTTP request and modify its corresponding response (Lines 3 and 4) in between. For example, if the user visits a Web page that has been personalized before, someactions would be taken

50、to tailor the Web page to meet the user preferences.Fig. 3. Browse Web pages via mobile devices.In order to achieve the above tasks, three components are designed in our system: Page Tailor,Configuration Manager, and Mobile Proxy. Thepurpose and functions of each component will be introduced separat
