OBJECTS OF WEB

• 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

• 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

OBJECTDS

• 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

STUDY ON WEB APPLICATION DEVELOPMENT

• 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

• 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

• 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
