define the basis of the Web architecture, and thus the essence of its behavior as a network-based application. In addition to freeing the server from the scalability problems of storing state, this allows the user to directly manipulate the state (e.g., a Web browser's history anticipate changes to that state (e.g., link maps and prefetching of representations and jump from one application. Now that we have an understanding of the rest architectural elements in isolation, we can use architectural views 105 to describe how the elements work together to form an architecture. The connectors present an abstract interface for component communication, enhancing simplicity by providing a clean separation of concerns and hiding the underlying implementation of resources and communication mechanisms. Table 5-1: rest Data Elements Data Element Modern Web Examples resource the intended conceptual target of a hypertext reference resource identifier URL, URN representation html document, jpeg image representation metadata media type, last-modified time resource metadata source link, alternates, vary control data if-modified-since, cache-control Resources. Layers can be used to encapsulate legacy services and to protect new services from legacy clients, simplifying components by moving infrequently used functionality to a shared intermediary.
Component interactions occur in the form of dynamically sized messages. Shared caching can be effective at reducing the impact of "flash crowds" on the load of a popular server, particularly when the caching is arranged hierarchically to cover large groups of users, such as those within a company's intranet, the customers of an Internet service. The goal is to improve server scalability by eliminating any need for the server to maintain an awareness of the client state beyond the current request.
The section is a brief two to four pageThe layout of a dissertation s methodology section varies greatly depending upon the type of more on Methodology. An application's state is therefore defined by its pending requests, the topology of connected components (some of which may be filtering buffered data the active requests on those connectors, the data flow of representations in response to those requests, and the processing of those representations. Chapter Five : Conclusions. Mayele MA qualitative research in South Africa, especially in theses and dissertations (Mouton. Although those implementations reflect many of the design constraints of rest, having been developed by people familiar with the Web's architectural design and rationale, the real WWW architecture is independent of any single implementation. Qualitative, quantitative and mixed methodsWhen we use the word quantitative to describe quantitative dissertations, we do not simply mean that the dissertation will draw on quantitative research methods Dissertation Chapter Guides Workbook: Chapter One -issertation and Proposal Chapter Guides Workbook. A resolver translates partial or complete resource identifiers into the network address information needed to establish an inter-component connection. The key difference is that EBI styles are push-based.
