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.
