<p>Web services provides a distributed computing architecture, with an emerging way of service oriented architecture (SQA). Here service oriented architecture is an interface to both computer systems and web services. Which implements an interaction with each other in new and different ways. According to service oriented architecture it virtually provides a platform for web services to communicate with each other. As it was an easy way for communicating with both clients and services. Many organizations and companies are either evaluating themselves into an enterprise information architectures, or they are in the process of getting adopt to the web services technology. As web services are platform independent it is playing a major role in the enterprise environment, and currently web services are widely accepted by many companies and organizations. So commonly web services possess some challenges to the enterprise environment. As a part of it web service must be tested before publish into a service oriented architecture. It involves large number of test cases, test scenarios that takes more time and effort. Testing management is needed so that it should control the time effort and should reduce the complexity of web service in a large software system, also in a real time world. Automation testing faces these challenges and fixes these issues. Automation testing has an ability to handle the complexities which are experiencing by the web services in a current environment. This paper presents the automatic testing strategies of a web service and detect the problems between both manual and automation testing. Finally results shows the proper effective report on improving the visibility of testing process based on the web approach to enhance the critical communication among multiple testing groups.</p>

Similarity Scores

Web service (WS) discovery is an essential task for implementing complex applications in a service oriented architecture (SOA), such as selecting, composing, and providing services. This task is limited semantically in the incorporation of the customer’s request and the web services. Furthermore, applying suitable similarity methods for the increasing number of WSs is more relevant for efficient web service discovery. To overcome these limitations, we propose a new approach for web service discovery integrating multiple similarity measures and k-means clustering. The approach enables more accurate services appropriate to the customer's request by calculating different similarity scores between the customer's request and the web services. The global semantic similarity is determined by applying k-means clustering using the obtained similarity scores. The experimental results demonstrated that the proposed semantic web service discovery approach outperforms the state-of-the approaches in terms of precision (98%), recall (95%), and F-measure (96%). The proposed approach is efficiently designed to support and facilitate the selection and composition of web services phases in complex applications.

Web Services are built on service-oriented architecture which is based on the notion of building applications by discovering and orchestrating services available on the web. Complex business processes can be realized by discovering and orchestrating already available services on the web. In order to make these orchestrated web services resilient to faults; we proposed a simple and elegant checkpointing policy called "Call based Global Checkpointing of Orchestrated web services" which specifies that when a web service calls another web service the calling web service has to save its state. But performance of the web services implementing this policy reduces due to checkpointing overhead. In an effort to improvise this policy, we propose in this paper, a checkpointing policy which uses Predicted Execution Time and Mean Time Between Failures of the called web services to make checkpointing decisions. This policy aims at reducing the required number of Call based Checkpoints but at the same time maintains the resilience of web services to faults.

Service Oriented Architecture (SOA) is an approach to build distributed systems that deliver application functionality as services that are language and platform-independent. Web service is one of the fundamental technologies in implementing SOA based applications. Web services are modular, self-describing, self-contained and loosely coupled applications that can be published, located, and invoked across the web. As the number of web services is increased, finding a set of suitable web service candidates with regard to a user’s requirement becomes a challenge. Web service discovery is the process of finding the most suitable service by matching service descriptions against service requests. Various approaches for web service discovery have been proposed. In this paper, we present an overview of different approaches for web service discovery described in the literature and try to classify them into different categories. We also determine the advantages and disadvantages of each category. The goal is to help researchers to propose a new approach or to select the most appropriate existing approach for service discovery.

Concise Description

One of the key challenges of the Service Oriented Architecture is the discovery of relevant services for a given task. In Semantic Web Services, service discovery is generally achieved by using the service profile ontology of OWL-S. Profile of a service is a derived, concise description and not a functional part of the semantic web service. There is no schema present in the service profile to describe the input, output (IO), and the IOs in the service profile are not always annotated with ontology concepts, whereas the process model has such a schema to describe the IOs which are always annotated with ontology concepts. In this paper, we propose a complementary sophisticated matchmaking approach which uses the concrete process model ontology of OWL-S instead of the concise service profile ontology. Empirical analysis shows that high precision and recall can be achieved by using the process model-based service discovery.

Web services are playing a pivotal role in business, management, governance, and society with the dramatic development of the Internet and the Web. However, many fundamental issues are still ignored to some extent. For example, what is the unified perspective to the state-of-the-art of Web services? What is the foundation of Demand-Driven Web Services (DDWS)? This chapter addresses these fundamental issues by examining the state-of-the-art of Web services and proposing a theoretical and technological foundation for demand-driven Web services with applications. This chapter also presents an extended Service-Oriented Architecture (SOA), eSMACS SOA, and examines main players in this architecture. This chapter then classifies DDWS as government DDWS, organizational DDWS, enterprise DDWS, customer DDWS, and citizen DDWS, and looks at the corresponding Web services. Finally, this chapter examines the theoretical, technical foundations for DDWS with applications. The proposed approaches will facilitate research and development of Web services, mobile services, cloud services, and social services.

More and more systems provide data through web service interfaces and these data have to be integrated with the legacy relational databases of the enterprise. The integration is usually done with enterprise information integration systems which provide a uniform query language to all information sources, therefore the XML data sources of Web services having a procedural access interface have to be matched with relational data sources having a database interface. In this chapter the authors provide a solution to this problem by describing the Web service wrapper component of the SINTAGMA Enterprise Information Integration system. They demonstrate Web services as XML data sources in enterprise information integration by showing how the web service wrapper component integrates XML data of Web services in the application domain of digital libraries.

Nowadays, it becomes very hard for anybody in the digital world to search and find suitable Web Services fit into his/her needs, since there is a huge amount of data on the Web caused by the enormous increasing of the Web providers and Web Services widespread in this digital community, and one of the most difficulties Web Services have to overcome, in the attempt to use the contents of the World Wide Web, is heterogeneity which is caused by the nature of the Web itself, and has two origins: data or public process heterogeneity. So it is highly required in such environment to have an intelligent mechanism in which every user can search according to his/her needs and later on can fulfill it in a semantic way. The authors will focus in this chapter on the public process heterogeneity which describes the behavior of the participants during a conversation, and propose a solution for dealing with it, explaining the functionality of the process mediator developed as a part of the Web Service Execution Environment (WSMX) and its mediation scenario, and will also apply this proposed solution on Federated Enterprise Resource Planning (FERP) system to get the semantic extension from it.

Service oriented architecture has revolutionized the way a traditional business process is executed. The success of this architecture is Indue to the composition of multiple heterogeneous services at runtime. Web service composition is a mechanism where several web services are combined at runtime to build a complex application for a user. It is one of the most sought after processes in the context of semantic web. But, composition of web services at runtime is a difficult task owing to the availability of multiple service providers offering the same functionality. The process if exasperated by due conflicting preferences of a service consumer. In this paper, the authors address the issue of selecting a service based on Quality of Service (QoS) attributes. They utilize concepts customized from physics to create an environment that facilitates the selection of a best service from the set of similar services. The technique not only facilitates the selection of the service with the best QoS attributes, but distributes the load among expeditiously. Here in this paper, the authors concentrate on minimizing and equitably balancing the waiting time for a user. They conduct in silico experiments on multiple workflows to demonstrate the efficacy of the proposed technique to balance load efficiently among similar service offerings.

Service Oriented Architecture (SOA) approach in general and the Web services technology in particular enable creation of business applications from independently developed, deployed and owned components called services. A service captures a distinct business function offering some value independently of its usage context. However, it is not enough to have the business functionality of the partners packaged as (Web) services; there is also a need for business-aligned order of interaction between these services a.k.a. business protocols, which can also be reused. The contribution of the chapter is two-fold: it explores reusability of the applicable business protocols in different business scenarios and also suggests possible ways to adapt the implementations of the partners’ services (end-points) to the changes in the business protocols.
