web application development

2. As we all know how the world is going digital and the web had evolved in to global environment for delivering all kinds of applications, • ranging from small scale and short lived services to large scale enterprise workflow systems distributed over many servers, applications that use HTML based front ends benefit from the pervasive destruction of web browsers for universal, cross-platform access. OBJECTS OF WEB

3. Another striking advantage of web deliver les in the concept of thin clients and centralized maintenance facilitating instantaneous ploy mint of software updated at minimal cost. • While the popularity of the web and its advantageous as client server platform have led to countless HTML based applications, the development of web application development is still mostly as hoc, there is no rigorous systematic approach and most current we application management practices rely on the knowledge and experiences of individual developers, one reason for the lack of a structure approach may be in the web legacy as an information medium rather than an application platform. • Web development is seen primarily as an authoring problem rather than s a software development to which well-established software engineering principal should apply OBJECTS

4. We believe another is that web implement model does not relate well to state of the art software development models. • web application development implementation is based on low level technologies that do not provide high level abstractions for sharing and re use seethe lack of suitable abstractions makes if difficult to construct frameworks that capture architectural design decision for reuse in different parts of an web application or in the different web application projects the lack of abstractions also makes it difficult to maintain and evolve web based applications , • design decision are very hard to track in a low level implementation as the web application development evolves changes can easily lead to inconsistencies. Because web applications development services tend to evolve quickly with frequent updates and redesign poor maintainability is a critical pro OBJECTDS

5. To illustrate some problems we found to be typical of web application development, we will describe a small part of a travel assistant systems that we developed over the past year. • The application integrates travel booking and routing systems for intermodal travel planning, the web was chosen as the integration platforms to capitalize on already existing travel information states on html browsers as a means of global systems access • .one requirement was for the application to support systems access for mobile handheld computer in principle state of the are handheld computers support html browsing but the small displays pose problems in rendering html a one size fits all design is obviously not satisfactory for deliver in web application development based user both standard desktop browser and handheld browsers instead web based user interfaces must be adapted to the different browsers characteristics and delivered accordingly. • The user interfaces primary in page out, while the content messages form elements and so on remain the same. STUDY ON WEB APPLICATION DEVELOPMENT

6. Thus the user interfaces design include recurring pattern based web application development in the well-known decorator pattern, below figure illustrates a pattern an html based user interface screens defined on an abstract label by a set of screen elements basically the content of the screen, • from the abstract screen specific screens are derived for each target browser platform works that are re defined In terms of a abstract objects such as the one described. • Nor can the model the, more specific in the figure, which is also based web application on an abstract and the notion of specialization by inheritance, • the lack of abstraction means that a web application development implementation cannot factor properties shared between objects into a generalized objects but must build them into each specific object, the alternatives of delegating shard code to a third object is also only minimally supported through extensions such as a server side incl STUDY ON WEB

7. Another problem also illustrates in our small example is the gap between higher level designs and implementation there is a drastic transition from the design as a represented in the object model , • its difficult to redesign during systems evolution because a wen implementation cannot figure the concept of the ordinal design, • the development process is not are visible which means that design decisions are difficult to tack and to access the implementation
