Ajax技術(shù)在流量分析系統(tǒng)中的應(yīng)用

摘  要
 Ajax為近兩年網(wǎng)路上熱門的討論話題，它的全名為Asynchronous java script and XML（異步的java script與XML），是一種建立互動(dòng)式網(wǎng)頁的瀏覽器端的開發(fā)技術(shù)，主要原理是運(yùn)用java script針對(duì)網(wǎng)頁文件DOM（Document Object Model）進(jìn)行動(dòng)態(tài)顯示及交互控制，并使用XML和XSLT進(jìn)行資料交換及相關(guān)操作。它的優(yōu)點(diǎn)是整個(gè)網(wǎng)頁頁面不需要重新下載，加快網(wǎng)頁界面顯示速度，減少網(wǎng)路流量，減輕服務(wù)器負(fù)擔(dān)，減少使用者等待頁面更新的時(shí)間，如果使用得當(dāng)，能建立更具互動(dòng)性與親和性的使用操作界面，讓執(zhí)行網(wǎng)絡(luò)應(yīng)用程序也能像桌面應(yīng)用程序一樣方便，靈活，快速。
 本文將Ajax技術(shù)運(yùn)用于流量分析系統(tǒng)的開發(fā)中，改善一般動(dòng)態(tài)資料庫網(wǎng)頁操作過程中，需要頻頻換頁與重新載入的弊病，減輕服務(wù)器負(fù)擔(dān)，解決前后端之間大量資料的傳輸及處理問題，明顯改善網(wǎng)頁資料的顯示及處理速度。并且本文還闡述了流量分析系統(tǒng)中系統(tǒng)管理模塊和流量分析模塊中實(shí)時(shí)模式的開發(fā)過程，包括系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn)。

Ajax Application in FlowAnalyzer System

Abstract
Ajax has becomes the popular topic of discussion on the Internet for the last two years.The name is shorthand for Asynchronous java script And XML what are development technologies to create an interactive Web browser.Its main principle is to run the dynamic display and interaction control using java script for Web Document DOM (Document Object Model)and use XML and XSLT to exchange informations and other related operations.Its advantage is the entire Web pages do not need to reload,speeding up the Web interface shows,reducing the network traffic,reducing the burden on the server, reducing the waiting time for users to update pages,and can establish more interactive and compatibility interfaces to use if used properly, so that the implementation of network applications can also like desktop applications,convenient,flexible,fast.    The Ajax technology will be used in the devlopment of the FlowAnalyzer system in this paper flow to treatment with the ills that need to change frequently and reloading the page in the course of operations for the general dynamic database pages,reduce the burden on the server,solve the problem of transfering and handling a great deal of informations between the front and end,improve the page display and information processing speed obviously.And this paper also described the development process of the system management model and the real-time pattern in the flow analysis module,including design and implementation.
