Advantages And Disadvantages Of Web Services

The semantic web is a vision created and promoted by Tim-Berners-Lee and the World Wide Web Consortium. In his article the Semantic Web in Scientific American (2001) Berners-Lee explains that The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation What Berners-Lee means by this is that in its current state, internet technology is not designed in a way in which computers and machines can interact with each other most efficiently. The primary reason for this disconnect is

Thus, the flexibility in SOA is made possible by loose coupling. However, optimization should be restricted to certain situations in SOA like when the Quality of Service (QoS) profiles are fixed and predetermined. Unfortunately, in the SOA environment optimization is an unfeasible expectation because of the dynamic environment of web services. Moreover, web service providers might not be willing to publish and create the profiles even though using QoS profiles are more reliable than other less-flexible optimization techniques. Thus, web services provide an organization with loosely coupled reusable software. Thus, this flexibility allows interoperability between systems to accomplish business functions. Further, business services can be completely allocated and decentralized over the Internet and collected by numerous communications

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.

In this task I will explain the main roles of web architecture with relation to communication and the ways we can communicate online. This task I will look at the main functions of Web 2.0 and will also evaluate on the architecture that comes with the Internet in order to allow for communication between software and application programs.

After the learning and the introspection regarding service and other areas of my life in the past several years, however, my views have expanded radically. I would still consider the actions above with service, however I would be able to provide a more accurate definition of service that is more nuanced and more complex than simply "being useful." My understanding of service now incorporates the real effects and the real intentions of an act, and the concept of

1) What are the two types of services that the Internet provides to its applications? What are some of characteristics of each of these services?

Effective connectivity: SOAP and RESTFUL Web Service callouts in CRM Adapter ensures seamless integration and effective connectivity therefore information in two systems be integrates automatically, without the need for users to perform manual data

The client and server architecture is a distributed application that divide the tasks between the entities that provides the resource or service, called servers, and the entities that request for a service, called clients. Fundamentally, clients and servers are two software entities where one software is fulfilling the request of another software entity. The client machine request for the service and the server machine interprets the request message received from the client machine. In order to fulfill the request of client machine, the server may have to refer various knowledge domains, process data and sometimes make an additional request to another server. The client and server may reside on the same machine or sometimes lie

Agents in MAS should interact for giving solutions and for solving some specific tasks. Agents act on behalf of users with different goals and motivations. So, they must have ability to cooperate, coordinate, collaborate and negotiate with each other to successfully interact in order to solve problems. Cooperation represents a general form of interaction between agents. Coordination is about organizing actions of different agents Multi-agent systems consist of agents and their environment. Typically multi-agent systems research refers to software agents. However, the agents in a multi-agent system are equally to the human. Multi Agent System is concerned for developing control the architecture of both single agent and multiagent. Multi Agent development tool is relatively new concept in artificial

Service" at the top and immediately below "You have created a service." If not, a

In this ideal architecture the whole process is divided into the three main components the mediator, customer and a group of data service providers. Previously there is no interaction between the customer and the data provider. And when the client sends a query, the mediator forwards the information to all data holders and via exchange of the acknowledgements, the mediator generates the connection with the data providers[4].

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 platform shows the middle tier, which is a prominent level of abstraction in an attempt to decouple prior firmly coupled legacy systems. The abstraction of legacy features, implementation, and technology specifies that applications are not a requirement for the other to understand because of

In this type of attack, an opponent alters or changes the service’s Web Services Description Language file where explanations about service examples are stored. If the opponent succeeds to interrupt service request code from WSDL file at distributing time, then this attack can be possible. Since Metadata documents are distributed using communication procedures like HTTP or e-mail they are expected to open the options of spoofing attacks. It is likely for attackers to maliciously modify the content of the WSDL file and allocate them across all the Web service clients. This has serious costs and security effects.

3. Communication between data sources and the metadata catalog with the middle and database tiers is done through which of the following? Mark for Review

The vision of the Semantic Web promises a kind Machine Intelligence, which can support a verity of user tasks like improved search engine or Question Answering (QA). Ontologies are needed for realization of the semantic web, which in turn depends on the ability of system to identify and take advantage of relationships that exist between and within ontologies. There are huge numbers of ontologies present on the web they need to be integrated for data integration. These ontologies are having different in representation, quality of data and larger sizes of ontologies, this lead to be problem during ontology mapping, on analyzing these problems and to introduce Multiagent mapping system. Main aim is to achieve heterogeneous data integration through semantic mapping of ontologies. this paper provide a mapping framework for Multiagent ontology having heterogeneous data in Semantic web and develop a question answering system from developed framework of ontology’s and improve performance by adding semantic relation interpreter which improves response time.
