【正文】 on enables the system to have someinsurmountable flaws, but adopted in the technology systemperformance to have the very big improvement, it mainly displayed infollowing several aspects: After 1. because the ASP page each time opens the process which allmust pass through first translates explained, therefore the pagerepeatedly is opening time speed not any promotion, after but page only needs a time of translation not to need retotranslate, is revised until this page or the Web application procedurerestarts. This enabled when visited many times the speed to have theenormous promotion. 2. because ASP has not provided any output data for the content part,therefore when uses ASP poses the database page only can drawsupport from ADO the RecordSet object to readby the pen takes therecord, but database part and so on DataGrid which providesthrough may directly with the database relation. 3. support application procedure realtime renewal. Themanager does not need to switch off the work server or not to evenneed to stop the application procedure the movement being allowed torenew the application document. The application procedure documentnever can lock, therefore even in procedure movement time the documentmay cover. After the file updating, the system can temperatelytransform to the new edition. 4. adopts Codebehind The way pilation codecauses the code to be easier to pile, the structure was clearer,reduced the system development and maintenance plex and theexpense. 1 system development principle based on technology system structural model The structure is three systems: UI level, service logiclevel and data level, The UI level is responsible with the user interactive, thereceive user39。 Many options including the news category, the origindepartment and so on only need to click on the mouse to be allowed toplete。其中新聞管理系統(tǒng)是構(gòu)成企業(yè)網(wǎng)站的一個重要組成部分，它擔(dān)負(fù)著雙層作用，一方面可以用來動態(tài)發(fā)布有關(guān)新產(chǎn)品或新開發(fā)項目，另一方面又可以及時向顧客公告企業(yè)經(jīng)營業(yè)績、技術(shù)與研發(fā)進(jìn)展、特別推薦或優(yōu)惠的工程項目、產(chǎn)品和服務(wù)，從而吸引顧客，擴(kuò)大顧客群。這使得在多次訪問時速度有了極大的提升。應(yīng)用程序文件永遠(yuǎn)不會被加鎖，因此甚至在程序運(yùn)行時文件就可以被覆蓋。它由 Web 表單、 XML Web 服務(wù)和組件服務(wù)組成。 3 種方式由于應(yīng)用層次的差異，使得效率由低到高，獨(dú)立性由高到低。當(dāng)瀏覽器向 Web 服務(wù)器請求網(wǎng)頁時，服務(wù)器處理這個請求，并將所請求的網(wǎng)頁發(fā)送給瀏覽器，然后連接就被斷開，直到瀏覽器發(fā)出下一個請求。不論數(shù)據(jù)從何處獲取，數(shù)據(jù)集都是通過使用同樣的程序模板而被操作的，并且它使用相同的潛在的數(shù)據(jù)緩沖區(qū)。注冊用戶除系統(tǒng)管理員外只能對自己錄入的新聞進(jìn)行刪改操作。 （ 4）方便移植：針對不同的企業(yè)，只需要稍作修改就可以開發(fā)出適合本企業(yè)特點(diǎn)的網(wǎng)站新聞管理系統(tǒng)！ 3 系統(tǒng)的詳細(xì)設(shè)計 系統(tǒng)的主要功能是通過幾個功能模塊來實(shí)現(xiàn)的。 ⑷ 新聞查詢：該模塊提供了新聞查詢功能，輸入待查找的內(nèi)容及選定分類信息可以快速地找到符合條件的新聞，并輸出查詢結(jié)果。該模塊還負(fù)責(zé)編輯狀態(tài)下的更新，這時，它將根據(jù)取得的 Title 字段值對頁面控件初始化。非新聞發(fā)布者除系統(tǒng)管理員外不具有對該條新聞的處理權(quán)限，所以不同用戶進(jìn)入此頁面將顯示不同的內(nèi)容。 ⑵ 新聞瀏覽：該模塊負(fù)責(zé)分頁列出網(wǎng)站所有新聞的信息，包括標(biāo)題、類型、來源部門字段及發(fā)布日期，每條新聞的標(biāo)題被做成一個超鏈接，點(diǎn)擊它們就能跳轉(zhuǎn)頁面進(jìn)行新 聞閱讀。 （ 2）即時可見：對新聞的處理（包括錄入、修改、刪除）將立即在主頁的對應(yīng)欄目顯示出來，達(dá)到即時發(fā)布、即時見效 的功能。圖 2 給出系統(tǒng)的功能結(jié)構(gòu)圖。一個數(shù)據(jù)集是內(nèi)存中提供數(shù)據(jù)關(guān)系圖的高速緩沖區(qū)。 傳統(tǒng)的應(yīng)用程序是通過先建立到數(shù)據(jù)庫的連接，在程序的整個運(yùn)行過程中維護(hù)連接的方式來設(shè)計
