| With the rapid development of computer hardware and network, C/S application which has been out of the market of enterprise application is refered to by customer again. Refering to C/S application is not caused by customer's following his heart. They hope to use applications with C/S's experience degree. The following will introduce the advantages and disadvantages of C/S developing mode.The C/S application responses fast and has beautiful UI(user interface). The C/S application also can be customized according to customer's requirement and implement complex business process. C/S application needs special client setup and its ability of distributed deployment is weak. Because a large number of clients don't have essentials for network, it's hard to deploy, install and configure quickly. It has great limitations when using defferent developing tool, such as high cost of developing and can be only developed by technical staff with some skills. Then B/S developing mode came into being. It is characterized by wide distribution and can be runned anytime and easy add functions and maintenance cost low and development cost low and sharing strong.The B/S applications hava so many advantages but customer begin to missing C/S applications.Because personalized characteristics reduce,Page refresh are depent on network. If network state is bad,the response speed will become slow.The B/S application can not implement paging display,database must bear more pressure.The client can achieve browse,query,data input functions,most functions are implemented by server.A technology and a framework which can develop B/S application which contains C/S characteristics are introduced in this article.Now one concept is widely mentioned which is Rich International Application. The development technology is Flex,use to develop client.With Flex,customized UI can be easy developed.Flex development need communicate with server.The server develop mode is J2EE which transimit data with Flex client. |
