3. Web technologies related to the interface
B/w Web services and their client. To
access web, the user need a computer
machine or related device, a browser on
the machine and an internet connection.
This information include programming
interface and languages And standards
for documents identification and display.

4. The World Wide Web was developed in 1989 by
English computer scientist Timothy Berners-Lee.
International World-Wide Web Consortium was
founded in January 1995 to guide the World Wide Web
by rising common protocols that support its evolution
and ensure its interoperability

5. Whenever a user wants
to access a web page the
first step is for the server-
name part of the URL to
be resolved. The next
step is for an HTTP
request to be sent to the
web server at that IP
address. Then web
browser displays the
page. Web pages contain
the links of other related
pages, or download and
web resources etc.

6. Since 1989 web has grown initially as a medium for
the broadcast of read-only material. Now a day, the
web users want all information on the web. Three
categories are as follows:
 Static document
 Dynamic Document
 Active Document

7. Web services are Internet enabled, self
contained applications that possesses the
capability of performing any tasks and
activities but can also involve other web
service to complete certain business related
activities.
Web services allow different applications
from different sources to communicate.

8. There are various phases or activities involved in the
life cycle of composite web service.

10. 1)Service wrapping: A native or legacy service can
be invoked by other web service can be planned
activities that need to be retrieved and assembled to
fulfil a service request.
2)Specification or Definition: Web services are
identified by available services at a level of
abstraction, external descriptions and service level
agreement. The user request task that needs to be
done with composition of services and abstract
specification along with functional and non-
functional requirements.

11. 3)Service planning and validation: The service is
planned on the basic of information given by the
processes that are published via the directories such
a UDDI (Universal Description, Discovery and
Integration).

12. 4)Service advertisement/Discovery: The Description of web
service is published in the service registry for the subsequent
discovery. The services discovered can be bound to design-
time binding/static binding or run-time binding/dynamic
binding.
5)Service Scheduling: Service composition need to be
scheduled according to the abstract definition provided by
the client that can be easily handled by the scheduler . Upon
its constituent service that can be based upon execution order
or dependencies among services.

13. 6)Service Negotiation: The web services are
negotiated, established for Contractual obligations
enforced with other services.
7)Service Evolution: Composite services need to be
adapted to accommodate organizational changes,
new technological opportunities and feedback from
monitoring is also considered during this phase.

14. [Benatallah et al. 2002, second] As a step further in
this direction, our ongoing work in the context of
the SELF-SERV project aims at providing high-
level modeling constructs and supporting tools to
search, compose, execute, monitor, an evolve Web
services. SELF-SERV provides a framework in
which services can be declaratively composed and
the resulting composite services can be executed in
a peer-to-peer way within a dynamic environment.
One of the main objectives of the project is to
devise novel integration techniques that allow fast
development of new services from existing ones.

15.  Our algorithms currently do not incorporate
variance or uncertainty in the response time of
web service, or more generally,quality of
service(QoS) information about web services .
It is important to address the problem of
finding plans that consistently choose the
highest-quality available web services and that
adapt to changes in web service response time.

16. Various theories and techniques are developed to
improve the web services. But with the growth of
internet usage the challenges listed below need to
be resolved efficiently.
 Optimised Web Services
 Web Service Composite correctness
 Time Limit
 Transaction Failures

17.  With the revolution of electronic media, world is
connected all time . The changes in the development,
life cycle activates, services of web were done from
time to time as per the requirements were increased. In
the modern era, there are many problems like security,
access time, numbers and type of users, heterogeneous
data on the web. In this research, the focus is on how
the life cycle and web services are affected as the
requirements and use of the web is increased.

18.  To compare various activities of Web
life cycle activities in Composite Web
Services from evolution of web to this
era.
 To analysis and propose the improved
Web life cycle activity framework for
Web Services.

19. The fundamental idea behind this research is to increase the
Efficient and reliable transmission over the network. The tools and
techniques used in the study will be:
•Study of Literature
•Analysis of different types of web services used
•On line Interpretation of Optimized results
•Research Paper publication
•Change order upon interrupts in form of feedback and publications
•Overall outcome processing, development of related facts
