公司信息,公司名稱、公司概述、公司地點等,可修改公司資料,只有先填寫了公司信息,才能發(fā)布招聘信息,確保信息的真實性。由于此工具最重要的評測標(biāo)準(zhǔn)就是速度,因此在設(shè)計過程中,具體過程盡量做到資源占用少,速度快。設(shè)計思想遵循以下幾點:(1) 采用B/S模式進(jìn)行開發(fā),其優(yōu)點是后臺與前臺處理層次分明,而且符合眾多已經(jīng)習(xí)慣網(wǎng)頁搜索方式的用戶。國內(nèi)外經(jīng)驗表明,一個成功的企業(yè)網(wǎng)站必須注重客戶的體驗,良好的客戶體驗才是將瀏覽者轉(zhuǎn)化為客戶的重要關(guān)鍵。輸入量越少,錯誤率就越少,數(shù)據(jù)準(zhǔn)備時間也減少。用戶界面是指軟件系統(tǒng)與用戶交互的接口,通常包括輸出、輸入、人機(jī)對話的界面格式等。企業(yè)用戶需求:企業(yè)可以使用系統(tǒng)注冊成為企業(yè)用戶并發(fā)布招聘信息。用戶的管理:可以查看普通(個人或者企業(yè))用戶創(chuàng)建的時間,查用戶角色,也可以刪除用戶。本網(wǎng)站主要實現(xiàn)的功能如下:包括與系統(tǒng)可靠性相關(guān)的各種指標(biāo)有:正常運行率、平均無故障時間、平均修復(fù)時間、精確度、最高錯誤或缺陷率。本網(wǎng)站無論是一般的用戶還是系統(tǒng)管理員只要通過身份驗證就可以通過互聯(lián)網(wǎng)對頁面進(jìn)行訪問。技術(shù)可行性是指使用現(xiàn)有的技術(shù)能否實現(xiàn)網(wǎng)站的設(shè)計開發(fā)與實現(xiàn)。XP操作系統(tǒng),SQL (9)共享組件的集成SQLServer2000利用新的 Web組件和位于瀏覽器中的 COM 控件,為用戶提供了多種查看和分析數(shù)據(jù)的方式。 (3)用于信息管理的強(qiáng)大解決方案高級用戶和開發(fā)人員可以創(chuàng)建那些將SQLServer2000界面(客戶端)的易用性和SQL服務(wù)器的可擴(kuò)展性和可靠性結(jié)合在一起的解決方案。ANSI(美國國家標(biāo)準(zhǔn)學(xué)會)聲稱,SQL是關(guān)系數(shù)據(jù)管理系統(tǒng)的標(biāo)準(zhǔn)語言。這使得Web頁面開發(fā)人員能夠使用熟悉的工具和如同標(biāo)識一樣的執(zhí)行特定功能的構(gòu)件來工作。(2)強(qiáng)調(diào)可重用的群組件絕大多數(shù)JSP頁面依賴于可重用且跨平臺的組件(如:JavaBeans或者Enterprise JavaBeans)來執(zhí)行應(yīng)用程序所要求的更為復(fù)雜的處理。 JSP簡介JSP是Sun公司推出的新一代網(wǎng)站開發(fā)語言,Sun公司借助自己在Java上的不凡造詣,將Java從Java應(yīng)用程序和Java Applet之外,又有新的碩果,就是JSP,Java Server Page。一兩年前還處于新興地位的博思人才網(wǎng)網(wǎng)絡(luò)招聘求職方式已經(jīng)名符其實地走向了招聘求職的主流地位。Internet上發(fā)布信息主要是通過網(wǎng)站來實現(xiàn)的,獲取信息也是要在Internet“海洋”中按照一定的檢索方式將所需要的信息從網(wǎng)站上下載下來。這與市場上的生產(chǎn)和消費兩者關(guān)系完全類似,消費促進(jìn)生產(chǎn),生產(chǎn)帶動消費。使用JSP標(biāo)識或者小腳本來產(chǎn)生頁面上的動態(tài)內(nèi)容。(3)采用標(biāo)識簡化頁面開發(fā)Web頁面開發(fā)人員不會都是熟悉腳本語言的程序設(shè)計人員。由于JSP頁面的內(nèi)置腳本語言是基于Java程序設(shè)計語言的,而且所有的JSP頁面都被編譯成為Java Servlet,JSP頁面就具有Java技術(shù)的所有好處,包括健壯的存儲管理和安全性。雖然絕大多數(shù)的數(shù)據(jù)庫系統(tǒng)使用SQL,但是它們同樣有它們自立另外的專有擴(kuò)展功能用于它們系統(tǒng)。例如,當(dāng)用戶重命名表中的字段時,將自動在諸如查詢的相關(guān)對象中進(jìn)行相應(yīng)的更改??尚行哉撟C其實是在更高層次上進(jìn)行的一次大大簡化的需求分析和設(shè)計。2008編譯工具。server只有先填寫了公司信息,才能發(fā)布招聘信息,確保信息的真實性。輸出設(shè)計的原則是考慮既要全面反映不同管理層的各項需要,又要言簡意賅,不要將用戶需要和不需要的都提供給用戶。(4)輸入數(shù)據(jù)盡早地用其處理所需的形式被記錄,以避免數(shù)據(jù)由一種介質(zhì)轉(zhuǎn)移到另一種介質(zhì)時需要轉(zhuǎn)錄而可能發(fā)生的錯誤。(3)“自頂向下”的原則。(3) 采用模塊化設(shè)計。根據(jù)對求職者和招聘單位的分析,按照系統(tǒng)開發(fā)的基本觀點對網(wǎng)站進(jìn)行分解,對網(wǎng)站做如下劃分:個人用戶:注冊、登錄、職位搜索、職位瀏覽及申請、應(yīng)聘記錄。求職人員可以注冊成為個人會員后通過該系統(tǒng)來發(fā)布求職信息。普通游客只能瀏覽、閱讀網(wǎng)站信息,注冊用戶除了可以完成普通用戶的操作外,個人用戶還可以進(jìn)行職位搜索、職位瀏覽及申請。在創(chuàng)建存儲過程時,就進(jìn)行了分析和優(yōu)化。數(shù)據(jù)庫的設(shè)計一般經(jīng)過規(guī)劃。管理員實體屬性圖如下:(3)新聞主要有標(biāo)題、內(nèi)容、時間等。介于本系統(tǒng)數(shù)據(jù)庫的簡單性,我們沒有采用聚集存儲之類的結(jié)構(gòu)設(shè)計。POPEDOM39。BOOKREADERS39。BOOKS39。 } public void doGet(HttpServletRequest request, HttpServletResponse response)個人用戶可以瀏覽招聘信息、發(fā)布求職信息、查看申請職位流程。這同時也意味著,最好別把文字的規(guī)格設(shè)得太小、也不能太大。有研究顯示,如果一個網(wǎng)站頁面的主體在15秒之內(nèi)顯示不出來,用戶會很快失去興趣。(3)運行結(jié)果如下圖: 新聞添加修改流程圖如下所示: 、修改、刪除流程圖實現(xiàn)關(guān)鍵代碼如下:public class NewsServlet extends HttpServlet { private ServletConfig config。 private TLiuyanDAO liuyanDAO。 ()。 在測試之初,由于將數(shù)據(jù)庫中的數(shù)據(jù)是隨便輸入,沒有實用性,為了使系統(tǒng)更加完善,在系統(tǒng)測試的過程中,本系統(tǒng)將一開始編程隨便輸入的數(shù)據(jù)全部清理后,輸入了一些有效的測試數(shù)據(jù),這樣可以更真實的反映系統(tǒng)的功能實現(xiàn)情況。前臺主要是后臺信息的管理,以及個人或企業(yè)用戶登錄發(fā)布或修改自己信息。就比如說在這次的設(shè)計,我不但對JSP和MS SQL SERVER2000有了深刻的認(rèn)識,積累了使用軟件工程的思想來開發(fā)軟件的經(jīng)驗,同時最重要的是摸索出了一套考慮問題和解決問題的方法,這對于我以后的學(xué)習(xí)受益匪淺。我會在以后的工作和學(xué)習(xí)中不斷完善自己,為我最熱愛的母校爭光,為自己翻開輝煌的新篇章。 Throughout the 1960s, Leonard Kleinrock, Paul Baran and Donald Davies independently conceptualized and developed network systems which used packets to transfer information between puters over a network.– Satellites municate via microwave radio waves, which are not deflected by the Earth39。t prevent sending large amounts of information.Communications protocols and network programmingA munications protocol is a set of rules for exchanging information over a network. In a protocol stack (also see the OSI model), each protocol leverages the services of the protocol below it. An important example of a protocol stack is HTTP running over TCP over IP over IEEE . (TCP and IP are members of the Internet Protocol Suite. IEEE is a member of the Ethernet protocol suite.) This stack is used between the wireless router and the home user39。– Wireless local area networks use a highfrequency radio technology similar to digital cellular and a lowfrequency radio technology. Wireless LANs use spread spectrum technology to enable munication between multiple devices in a limited area. IEEE defines a mon flavor of openstandards wireless radiowave technology.Infrared munication can transmit signals for small distances, typically no more than 10 meters. In most cases, lineofsight propagation is used, which limits the physical positioning of municating devices.A global area network (GAN) is a network used for supporting mobile across an arbitrary number of wireless LANs, satellite coverage areas, etc. The key challenge in mobile munications is handing off user munications from one local coverage area to the next. In IEEE Project 802, this involves a succession of terrestrial wireless LANs.[4]Exotic technologiesThere have been various attempts at transporting data over exotic media: In 1972, mercial services using were deployed, and later used as an underlying infrastructure for expanding TCP/IP networks.Today, puter networks are the core of modern munication. All modern aspects of the public switched telephone network (PSTN) are putercontrolled. Telephony increasingly runs over the Internet Protocol, although not necessarily the public Internet. The scope of munication has increased significantly in the past decade. This boom in munications would not have been possible without the progressively advancing puter network. Computer networks, and the technologies that make munication between networked puters possible, continue to drive puter hardware, software, and peripherals industries. The expansion of related industries is mirrored by growth in the numbers and types of people using networks, from the researcher to the home user.An interconnected collection of autonomous puters (unique identity) is known as a puter network.PropertiesA puter network has the following properties:Facilitates interpersonal municationsPeople can municate efficiently and easily via , instant messaging, chat rooms, telephone, video telephone calls, and video conferencing.Allows sharing of files, data, and other types of informationAuthorized users may access information stored on other puters on the network. Providing access to information on shared storage devices is an important feature of many networks.Allows sharing of network and puting resourcesUsers may access and use resources provided by devices on the network, such as printing a docum
