10/08/2006 Characteristics of Conventional web Applications "Click. wait. and refresh"user interaction Page refreshes from the server needed for all events, data submissions, and navigation Synchronous "request/response"communication mode the user has to wait for the response Page-driven: Workflow is based on pages Page-navigation logic is determined by the server So these are characteristics rather limitations of the conventional web applications First, in a conventional web application, a user interaction is basically a repeated sequence of " click, wait and refresh cycles. In fact, a total page refresh has to occur for anything you do with the server whether it is to send a small piece of data to the server, or retrieving a small piece of data from the server Then the user has to wait for the arrival of the response from the server. This interaction is considered synchronous in the sense that the user has to wait until a response from the server is received. of course we all know what it means hen the network is down or slow-blank screen The flow of conventional web application is page-driven meaning the workflow of the application is based on pages And which page to display next is determined by the serverSo these are characteristics, rather limitations of the conventional web applications. First, in a conventional web application, a user interaction is basically a repeated sequence of “click, wait and refresh” cycles. In fact, a total page refresh has to occur for anything you do with the server whether it is to send a small piece of data to the server, or retrieving a small piece of data from the server. Then the user has to wait for the arrival of the response from the server. This interaction is considered synchronous in the sense that the user has to wait until a response from the server is received. Of course, we all know what it means when the network is down or slow - blank screen. The flow of conventional web application is page-driven meaning the workflow of the application is based on pages. And which page to display next is determined by the server. 7 Characteristics of Conventional Web Applications • “Click, wait, and refresh” user interaction > Page refreshes from the server needed for all events, data submissions, and navigation • Synchronous “request/response” communication model > The user has to wait for the response • Page-driven: Workflow is based on pages > Page-navigation logic is determined by the server 10/08/2006
