Regardless of the latest news regarding Service–Oriented Architecture (SOA) failures, it is still clearly the choice for system integration and advantage
on legacy systems. The expertise needed to put in place SOA will surely change to report developing requirements, but the theory will stay. The legacy
systems act as a hub for various clients design distributes applications, which locate information through the five–web endpoint. The EAI retailer's

The web services technology utilizes the wrapped legacy system elements in the beginning and then switch them with brand new components (Lewis,
Smith, & Kontogiannis, 2010). Legacy systems are referred to large software systems that companies do not understand how to handle but the systems
are important to the corporation. The software used in the legacy systems written some time ago with old fashion techniques, it continues to operate.
To migrate and modernize the baggage that was used in the past would create a technical and nontechnical demand, with issues from explaining the
cost of justifying the expense in doing business with external contractors to using program knowledge and visualization methods (Bennett, 1995).
While other might describe legacy systems as current Information Systems used previously and runs vital, company procedures within the present
enterprise IT architecture. Legacy plays a vital part and is thought of as the heart of businesses operating revenue making it a business value for the
firm (Shahbaz & Galinium, 2009). The procedures of migrating to SOA is considered from two separate perspectives the IT (technical) and company

Dynamic Composition Of Distributed System Or Multi Agent
Dynamic composition in distributed system or multi–agent system has long time been a hot field in research community. This report investigates some
models and languages which have been developed in recent years and used to model multi–agent and distributed system. By comparing their
advantages and drawbacks, some proposals are given for possible future research. Author Keywords Coordination language, Linda, GALS, SystemJ I.
INTRODUCTION In recent years, with the popularity of service orientation architecture, many modern business applications adhere to the paradigms
of service orientation and service oriented architectures in order to create loosely coupled, modular software systems, which is easy to be maintained
and extended. In the field of automation and control systems, SOA–based flexibility is of even more interest, because it contributes not only to
substantial reductions of installation and setup costs. These costs are of particular importance since manufacturing plants again and again have to be
adapted to new products resulting in changes of the technical equipment and the process flows performed. One of the proposed approaches to achieve
this goal is the creation of new services by composing already existing ones, instead of building up everything from scratches. This is called process
service composition. Service composition facilitates the creation of innovative services that suit the end–user needs, with a reduced time to–market and
better component reuse.

Advantages And Disadvantages Of Grid Computing
This paper gives an overview about Grid Computing and the various key issues related to that.Today we are in the Internet world and everyone prefers
to get fast access to the Internet. The growth of the internet with various resources and high speed networks changes the society enormously. We can
improve the speed of the computer using Grid. This paper presents clearly the vision of the grid computing and the architecture of grid computing.The
advantages and the disadvantages of the grid computing has also been discussed.

resources efficiently and securely. Grid computing is an... Show more content on Helpwriting.net ...
The main services provided through utility grids are software and special equipments. For instance, the applications can be run on one machine and all
the users can send their data to be processed to that machine and receive the result back.Grid Computing will not come in reality unless it provides a
core of services ,reliability and enough usability1.
III. Advantages and Disadvantages
There is no need to have large number of SMP servers. It efficiently uses the idle resources. If there is any failure in one grid ,the grid environment
automatically uses the other resources. Easy to scalable. Jobs can be executed in parallel and increase the speed of the computation. Grid computing
consists of some disadvantages too. Some applications need to be modified in order to use this application in grid computing. The applications which
are not designed to use an MPI (Message Passing Interface) will have to revert to an SMP (Symmetric Multi–Processing). Grid computing requires an
advanced infrastructure like small servers, fast connections between the servers and the use of quality tools, software and skilled technicians to
manage the grid.This grid computing is also costly and security issues also need to be

different models of data storage in cloud and researches targeted most common cloud storage services like dropbox, unity e.t.c as these are more
vulnerable to attacks by malicious parties. With the grown internet usage, the file sharing through internet has been increased in recent years leading to
increase in the number of attacks.
2.1 Attacks on Dropbox
Dropbox is one such service that carries out file storing and sharing on large scale. It can be used to store the files, back up the files, ... Show more
Dropbox uses Amazon S3 storage service to store the encrypted data that has been uploaded. Even though most of the Dropbox code is written in
python, instead of using hashlib of python, it assigns the calculation of SHA–256 hash values to a wrapper library NCrypto. A malicious attacker can
modify NCrypto source code that is available publicly, such that it replaces the hash value of the uploaded file with his own hash value. So if the
attacker already knows the hash values of the victim 's file that has already been stored in the server, he can directly download the files from the
server as the server completely trusts the hash value calculation from the client. Thus by manipulating the hash values, one can get access to files
of other client 's that are stored in the dropbox. Dropbox can be installed on any device that it is compatible with and the user is registered to
dropbox by a unique HostID. By thieving the HostId, an attacker can get access to all the files stored in victim 's dropbox account. The attacker can
also link whimsical files to the victim 's dropbox account. The transmission of data from the local system to sever is built upon HTTPS. By using
any valid HostId any creating HTTP request, one can access files that are present in the dropbox server. These attacks can be used in different ways to
smuggle the data from a client. The attacker can act as a middle man between the victim and the dropbox. When the victim

There are three major cloud deployment models along with few other emerging models like federated and intercloud [1].
Private Cloud
Private cloud is the best choice for companies that already own datacenter and developed IT infrastructure and have specific needs around security or
performance. The cloud is managed, owned, and operated by the organization, a third party, or some combination of them, and it may exist on or off
premises.
Public Cloud
Public cloud is the infrastructure for open use. It is hosted on the premises of the cloud provider. Public cloud is flexible, scalable and cost–effective.
The data and processing environment are not under control of enterprises. The model is not suitable for applications or data with a security requirement.
Hybrid Cloud
Hybrid Cloud is a combination of cloud infrastructures (public, private, or community) that remain unique but are tied together by standardized
technology that enables application and data portability. Hybrid cloud is the most complicated configuration to manage and the most economical
model. It combines benefits of the secured environment in private clouds and rapid elasticity of public clouds.
Service Models
There are three widely used and accepted cloud service models. Service models like Data Analytics as a Service and HPC/Grid as a Service are
emerging as useful models [1]. One can select an appropriate service model based on the availability of suitable application, development and test

Comparing Web Services, Cloud Computing, and how Cloud Computing Impacts Companies Cloud Computing and Web Services have become well
known services that companies have been using. Web services provide the ways that organizations can use applications to communicate with each other
across the internet. Cloud computing provides various types of service, such as software as a service, where a provider gives the company software that
they can use for their business functions. While this may seem that both types of services are different from each other, they do share similarities that
companies should take notice. Service oriented architecture has also started to become a useful feature that helps with integration in companies. One
problem is that some companies have difficulty in implementing service oriented architecture, but cloud computing has started to become an option that
has caused an impact in service oriented architecture and integration. Software as a service in cloud computing does share similarities with web
services, one of them being that they take advantage of the internet. By using the internet, companies can use the services effectively, such as having a
good of communicating applications across system, and obtaining software that they would require for their business functions. Other similarities are
that the services help with integration. With web services, communication between systems becomes easier

This enables software to derive some of its functionality from other applications, hence being service–oriented applications.
Properties of a service–oriented architecture:
Self–contained web service: The client should contain no services itself and no additional software. The use of a programming language that can access
a server should be enough.
Self–describing web service: The data being handled should be self–describing. No additional software should be used to decode data being handled.
The client only retrieves from the server.
Follow strict standards: XML and HTTP being the most common basis for web services.
Programmatic access to data: SOA provides data at the most simple level. No GUI should be provided.
Language–independent web services: The client that is using the web services of a server do not have to be on the same platform or be using the
same language. Standard transfer protocols are used to send and receive data.
In order for a system to resourcefully use SOA, it must meet the following standards:
In service oriented architecture, services are independent elements of functionality.
Interoperability among different systems and programming languages that delivers the foundation for integration between applications on a diverse

range of platforms through a communications protocol
Clear–cut descriptive language. To use services from a provided system by clearly defined

Problem 3: This problem is a piece of large effort required to upgrade infrastructure for various products to support latest version of Java 1.8 and
latest versions of TLS (TLSv1.1 and TLS 1.2). Approach used for solving this problem includes following steps: 1) Read BDR of products and
understand architecture of product. 2) Check code of products and identify external JAR file used by products. 3) Research JAR file on their
official website and other reliable sources. 4) Gather initial information and consult with other senior team members who are familiar with particular
product in detail. 5) Groom with the team based on initial finding and add conclusive summary for initial research for each JAR. Knowledge of
various software and third party jars used in different subjects like Bouncy Castle JAR used for encryption algorithms which I had knowledge of while

organization. A proposed organizational structure for IT department that would sustain the transformation of AgCredit into a process
–centric
organization is different than what they exploit currently. Centralized IT structure would fit best for AgCredit's upcoming transformation. This will
help company since centralized structure would require taking orders from higher management. Employees will understand more of the company's
vision when they take direct orders from higher management. To make sure the entire project is done right a more navigated team will be needed,
they will also be able to help through approval process of all projects. To make this transformation process smoother conversion team will need to
ensure all the business and IT projects fit within a service oriented architecture (SOA) framework. CEO and CIO both should be involved in all these
diverse team so they can keep eyes on all the work that is being taking place and also to make sure employees are working towards the right direction.
CFO also should be involved in both business and IT departments, where he can give a better understanding of cost components. It would be helpful if
they also hire someone from outside with senior management experience, who can help company with business

Software Localization Strategies
2. LOCALIZATION STRATEGIES
There are two possible strategies for software localization as:
2.1. For designing a new localized software product
This strategy based on designing and developing a software product according to specific culture from scratch. Developer can put every resources
needed for localized software product in some type of resource repository. This repository may be Windows resource files, .NET assemble files, or a
database. This resource repository is easily editable, and also eliminates the need for source code recompiling.
2.2. For localizing an already existing software product
Here it is assumed that the source code (in the source language) for the software product to be localized is already available. This strategy reuses the
existing software product for the target locale. The localization tool explained in this paper is based on this strategy. Programmer has the code of
notepad software (available in English) and this code pass as input test case to the tool.
3. SERVICE ORIENTED ARCHITECTURE
Service oriented architecture is software architecture design pattern that provide application functionality as services, known as Service–orientation.
Similar to cloud computing in SOA services are shared and there exists a cloud of services. Hence SOA based on the concept of cloud computing.
Cloud computing used to describe a variety of different types of computing concepts that involve a large number of computers connected through a

Wal Mart And Sainsbury Target Mass Social Target Audience
The following report takes into account the selection of two integral companies with global operations, Wal–Mart and Sainsbury. These two companies
are critically assessed in link to their individual brand positioning strategies. Some strategies overlap each other whereas some are different, so both are
discussed in context. The brand positioning strategy has taken into account the individual companies' marketing objectives, sales pitches, expansive
strategies and service competition that are provided nationally and internationally. Wal–Mart has its extensive operations, hence has a more generic
service oriented approach where products are sold and retailed in an intelligent global manner. In this context, its international website layout, online
presence and promotional campaigns are discussed that hopes to target mass social target audience. On the other hand, Sainsbury deals in the same
business of retail and online shopping, but since its operations are more suited and favorable in the United Kingdom, that is why its operations are
limited compared to Wal–Mart. Sainsbury deals with niche market segment, which is limited by some geographic and demographic segmentation.
Sainsbury's promotional and marketing campaigns are also less generic, and keep intact its present social and cultural context. Both companies are
suggested for service development, market penetration and market developments. Since both companies are rates exceptionally agile, they still compete

Advantages And Disadvantages Of SOA Project
Abstract: In the last few decades SOA (Service Oriented Architecture) has become the new trend in the IT industry. Many organizations tend to migrate
to SOA in order to cope with the rapidly changing business. Effort estimation of SOA projects has become a real challenge to project managers due to
the limited literatures addressing this issue. The traditional effort estimation techniques do not fit SOA projects entirely, as SOA has unique
characteristics were not addressed by the traditional cost estimation approaches. These characteristics include: loose coupling, reusability, composability
and discoverability. On the other hand, SOA cost estimation approaches are still immature and can't be used in real life projects, as they are more
guidelines... Show more content on Helpwriting.net ...
Also, it is more guidelines than a practical cost estimation approach, which makes it hard to be applied in real projects.
AUS–SMAT Framework:
AUS–SMAT Framework вЂЋwas developed by NICTA organizationвЂЋвЂЋ[7]. It aims to develop a framework for scope, cost and effort for SOA
projects. In this framework the SOA project is decomposed into its constituent services. Each service is classified to its type either: service mining,
service development, service integration or application development. Each service type has its own specific activities, templates, cost factors and cost
functions. The overall cost of the project will be a summation of the cost of its constituent services.
Divide and Conquer (D&C) Approach: The Divide and Conquer approachвЂЋвЂЋвЂЋ вЂЋ[5] was inspired from the divide and conquer algorithm
that is used to solve complicated problems. This cost estimation approach not only takes the advantage of composability nature of services but also
solves the complexity problem of SOA. The whole project is broken down into services; the cost of each service is estimated. The overall cost of the
application is the summation of the cost of the component services вЂЋвЂЋ

The Technology Assets are becoming more complex and businesses are increasingly dependent upon these resources. It is important for IT managers to

help business managers understand the value of standard IT platforms across the organization to ensure reliable computer and communications
operations.
In addition to effectively managing the technological assets, IT managers must continually evaluate the Relationship Assets: how well the IS
department is working with business managers so that IT investment and implementation decisions are made that benefit the organization. IT leaders
who partner well with business managers are most likely to implement IT solutions that provide value to the business organization.

Microservices are a method of designing software applications in which the application components are divided into small independent processes called
Microservices which communicate with each other using API to form a complete application.

updated version of earlier technology. Many enterprises that use computers have legacy platforms, as well as legacy applications, that serve critical
business needs" (Rouse, 2017). For example, a large amount of banks and government entities still utilize legacy systems. Why would organizations
want to use outdated operating systems when there are likely new, better alternatives? In short, legacy systems have been altered so much over the

As stated previously, the adoption of service–oriented architecture can bring forth various complexities due to the nature of its design. For this reason,
it is necessary for organizations to make a considerable initial investment into adopting a service–oriented architecture design. In order to make
service–oriented architecture work well for an organization, there must first be a substantial analysis of every facet of the initiative. "The construction
of services can be expensive and time–consuming, introducing a more burdensome project delivery lifecycle, further compounded by some of the
top–down analysis requirements that may need to be in place before services can be built" (Erl, 2008, p. 88). The complexities of analyzing,

Web Service And Web Services
ABSTRACT
Web Services are modular, self–describing, self–contained and loosely coupled applications that can be published, located, and invoked across the
web. With the increasing number of web services available on the web, the need for web services composition is becoming more and more important.
Nowadays, for answering complex needs of users, the construction of new web services based on existing ones is required.
This problem is known as web services composition. However, it is one of big challenge problems of recent years in a distributed and dynamic
environment. The various approaches in field of web service compositions proposed by the researchers. In this paper we present a review of existing
approaches for web service composition and compare them among each other with respect to some key requirements. We hope this paper helps
researchers to focus on their efforts and to deliver lasting solutions in this field.

The Four Primary Design Principles Of Service Oriented...
One of the four primary design principles of service oriented architecture is service reusability is one of the design principles that are most commonly
incorporated within the service model process. The text defines service reusability as being responsible for defining the inventory blueprint, grouping
logic within the contexts of proposed agnostic service candidates and refining functionality (Thomas, 2008). The goals of a traditional system does not
differ much from this model, because they both focus on identifying and refining functionality. The next most commonly incorporated design principle
is service autonomy. The service autonomy process involves gathering and analyzing information about the system in order to prevent future mishaps....
I worked for a company named Fleet Management Expansion, which was responsible for maintaining equipment readiness, data management systems
and reporting. One of the issues that we dealt with was linking our host systems to our client systems in real–time. The equipment that we had was
separated by different unit ownership. Sometimes the equipment was located in separated areas from the main location. In these instances, we had to
set up client data management systems that displayed in real–time with the host systems. Setting this up in a top–down sequence would not be feasible
for this operation, because the main focus is not on the subsystem (client), the host has to be set up properly before the focus could lean toward the
client. If the client system had to be reverse engineered in order to setup the host system, then the top–down model would be sufficient. In our case we
used the bottom–up model to set up our data management systems. We made sure that all the details were covered at the host level first and then
moved on to the client. We made sure that the time zone was in sync, oracle was set up properly in order for the systems to interface and the data that
was in the systems was input correctly. Afterwards, we made a backup of the host system and loaded it on the client system; allowing changes to be

Service–Oriented Architecture
Software Architecture is how a system is structured, it is a collection of all the elements that are what make the system, there are several different
styles which can be used to create a Program or
Programs. Software Architecture styles will describe the classes of the architecture being used, these classes of course can be used repeatedly, there are
known practices that allow the reuse ( Clements, Kazman & Klein "Evaluating Software Architecture", 2002).

Resource – Oriented Architecture
Resource – Oriented Architecture (ROA) is the structural design supporting the internetworking of resources. A resource in this context is any entity
that can be identified and assigned a uniform resource identifier ( URI) (whatis.techtarget.com). Per Dr. Roy Fielding, Resource–oriented software is
known as an architectural style that exploits the existing technology and protocols of the web, including HTTP and XML. There are four concepts that
are most essential for ROA's which are:
Resources
Names (URIs)
What they represent
Links between each
And there are also four properties;
Addressability
Uniform Interface
Statelessness
Connectedness (whatis.techtarget.com).
With ROA's it is very important to first determine what should be considered as a Resource, this is what really distinguishes the difference between
the SOA's and the ROA's, once this has been done the next thing would be to determine the resource types and how to invoke methods and also how

to correspond to the responses. The resources will be accessed through the HTTP interface. Because the Resource – Oriented Architectures are still in
its beginning stages, in my opinion, I don't believe it would be the best choice between itself and a Service– Oriented
Architecture at this time, I honestly believe

ABSTRACT:– A Service Oriented Architecture is essentially a collection of services. These services communicate with each other. The communication
can involve either simple data passing or it could involve two or more services coordinating some activity.

Service autonomy is the term used to describe a service which is sel–sufficient in terms of managing all the necessary logic, resources and environment
and which is independent of external devices.
пѓ Business–Driven Infrastructure on–demand
Using service–orientation for the infrastructure provides a way to define dependencies of higher–level business services on the lower–level
infrastructure services, dow to the actual physical resources, such as network appliances, storage, and servers.
пѓ Service Management
Service–orientation defines service–level objectives as well as the measurement of the delivery of those objectives.
CONCLUSION:– Service–Oriented Architectures are rapidly being accepted by the IT world as a sound, modularized approach for building and
deploying services across the extended enterprise. Practical extension of these architectures requires careful planning. The SOA is mainly implemented
with web services. In this paper I have tried to explain the so many things about service oriented architecture I and I think this paper will help to other
for further study in the service oriented architecture.

The Invoice Of Customer Service Department
1)Local data: let us consider example of organization as amazon which maintains vast amount of data. It contains departments like developers, database
administrators, sales and many more. When local data is taken into consideration, for example, in sales if we take delivery service department. It
simply considers invoice of customer as it will start it service and keeps track until courier is delivered. After delivering, invoice will be erased from
their system as they won't be connected in remaining issues. This invoice number can also be used across the organization i.e. if we consider customer
service department they should maintain this invoice in order to inform details if any customer approaches them before delivery.
Shared data: To get a clear view on shared data we will consider sales department and analyst. In sales department, they have all the information like
product ordered, cancelled, insufficient funds, returned and it will be differed from time to time. When an analyst would like to go through the graph
of products sale they just need the data of products purchased which doesn't include orders cancelled, insufficient funds. So, data will be shared
between departments which can be altered from time to time.
Core data: In core data let us consider managing department, if they apply any changes to models whole organization will be upgraded. Core Data
portrays information with a high level data model communicated as far as entities and their relationships in

The Unreliable Web Services Revolution
The Untrustworthy Web Services Revolution Group No:15 Nishank Jain, Kartik Patel, Mayank Deora, Nallagatla Manikanta, Rishabh Chhabra
Summary:
Web services are software systems which are designed to support data transfer and exchange of information over a network. Web services use
various open standards like TCP, IP, HTML, and Java. Ever increasing demand for higher data transfer rates requires systems which can handle large
volume of data. The data should not be vulnerable to attack from hackers else many business organizations will go red (i.e. in loss).
The major hurdle in the development of reliable web services is the lack of trust in technology.
We should begin to take control of those limitations, rather than blindly building and deploying systems that simply cannot rise to the level of trust that
their roles demand.
The most important benefits of using trustworthy web services is interoperability and reusability.
Interoperability means programmers can use any programming language to access the web service using standard based communications that are
platform independent. Web services can be implemented in different applications without making an entirely new web service for a new application.
Application can choose from the existing web services and extend them to meet its requirement.
Coming to the disadvantages of web services, the major concern is security and reliability. The commoditization of the Web is bringing various
benefits, but also some serious

In the literature analysis, alternates are used to differentiate between the characteristics of the information that had been saved in files on a computer
as a soft copy and the information that had been saved in less thoroughly reviewed outlet. This review identifies more focused literature requirements
for the literature survey phase of the research. More specific topics give a solid background and knowledge to develop a model and methodology to
solve the research problems. The study of this research builds the prototype model. Building stage is the phase of the requirements, design, specifying
software tools, and designing the interfaces. Prototyping stage is the phase of coding and testing. The study of this research will prove that the model
works. The model provides prototyping stage developer with outlines to follow. There are three approaches. The first is top down. That is, the research
starts from the top component and ends with the bottom component. The second is bottom up; the research starts from the bottom component and ends
with the top component. The third is hybrid; the research starts from the middle of the model and ends with both the top and bottom components. 2.1

Service Orientated Architecture Analysis
Three factors that would encourage an organization to adopt a Service–Orientated Architecture (SOA) are the portability, the reusability, and
connectivity (Birekul & Dogerlioglu, 2011). In the area of portability one example of an SOA is video games. More companies are getting away
from the player being tied to a disk. They are instead "separating the game from the game engine" (BinSubaih & Maddock, 2007). By doing this
they are able to allow a player to keep different aspects of the game mobile or portable like the "game logic, the object model, and the game state
(brain)" (BinSubaih & Maddock, 2007). In doing this they also make development time shorter since the game engine is reusable. This leads me to my

To be able to compare and contrast a service and an object as a building block for defining new software one must first define what each one is. "A
service is a physically independent software component designed to carry out a specific goal" (Richardson, 2017). An example in our attend section
was a task that was a form that can be completed using a service is the processing of a business form. A service is also considered "a logical
manifestation of some physical resource (like database, programs, devices, or humans) grouped as a process that an organization exposes to the
network" (SYS–CON Media Inc, 2004). Another business problem that is solved with a service is production schedule. A plant manager uses a
production schedule to be sure that the plant is running smoothly. They require the customer service department and sales to input their orders which
will translate into what needs to be done each day to help with line balance in the plant. There are different types of services depending on what is
needed. According to our attend section, they are as follows:
Task service is the most comprehensive therefor the least interoperable.
Entity service is the most reusable and usually contain the create, read, update, and delete methods.

WEB SERVICES AND SEMANTIC WEB
The question of the relationship between these two activities is constantly in the air.
The whole description side is a clear semantic web application, and so long as XML languages are defined which introduced with English language
specs but no RDF mapping, there is a potential ambiguity which will have to be resolved later in making that mapping, there is an inability to use
common semantic web tools, and there is cost down the road assuming semantic web tools will eventually be used. Essentially, web serve ices become
instant legacy technology for the semantic web.
The DAML–services collation of researchers is tackling the job of service description at a higher level.
Many things which are described as web services can in fact be described as the publication of a series of semantic web documents, just as the billing
of a peer company is in reality effected by the issuance of an invoice.
When Semantic Web agents query each other, they could use SOAP (though a direct encoding into an HTTP URI may also be effective).
When Semantic Web agents update each other, they should use SOAP, running typically over HTTP POST.

Many businesses may decide to integrate Service Oriented Architecture with legacy systems to standardize systems across the organization. An
organization's reliance on legacy systems may limit their ability to adopt SOA on a large scale. There are ways of mitigating the transition legacy
systems to service orientation. Legacy systems become costly and affect efficiency throughout organizations. They lack the flexibility needed to
perform modifications. Ideally, a legacy system would be compatible with other systems across the company in a standardized fashion, therefore a

Time constraint and running out of funds may be avoided by utilizing a bottom up method if necessary, or even combining this with a top down
approach. A true analysis of the needs of the organization needs to be assessed and working closely with designers is a necessity. Instead of letting an
obsolete legacy system hinder upgrade attempts, consider re–engineering it. Companies may also find success in completing the migrations and
transition in phases instead of trying to complete the entire project at once.

Web Service Developments And Standards
chapter{Introduction}label{C:intro} section{Introduction} Modern enterprises need to respond effectively and quickly to opportunities in today 's
competitive and global markets.
To accommodate business agility, companies are supposed start with use existing applications instead of developing them from scratch.
A contemporary approach for addressing these critical issues is embodied by (Web) services that can be easily assembled to form a collection of
autonomous and loosely coupled business processes cite{Papazoglou}.
The arising of Web service developments and standards in support of automated business integration has driven major technological advances in the
integration software space, most notably, the Service Oriented Architecture (SOA) cite{Dan:2008}. In an SOA, software resources are packaged as
Web services, which are well defined, self–contained modules that provide standard business functionality and are independent of the state or context
of other services cite{Ran}.
A Web service is a software system allowing to expose services viaInternet. The
SOA promotes the composition of coarse–grained Web services to build more complex web applications using standards such as WS–BPEL cite{std
/ws–bpel2}. Because of the convenience, low cost cite{Aboolian} and capacity to be composed into high–level business processes, Web service
technology is becoming increasing popular.

anything help her. She told me that she's learning to use Microsoft Word 2010 to create a simple document. Then, I asked her why she doesn't come
to the basic computer using class at CALT building because it will be easily for her to learn how to use new technology in computer where she can
