Web Services

April 28, 2010 by BPELresource.com 5 Comments

Product Description
Like many other incipient technologies, Web services are still surrounded by a tremendous level of noise. This noise results from the always dangerous combination of wishful thinking on the part of research and industry and of a lack of clear understanding of how Web services came to be. On the one hand, multiple contradictory interpretations are created by the many attempts to realign existing technology and strategies with Web services. On the other hand, the emphasis on what could be done with Web services in the future often makes us lose track of what can be really done with Web services today and in the short term. These factors make it extremely difficult to get a coherent picture of what Web services are, what they contribute, and where they will be applied.

Alonso and his co-authors deliberately take a step back. Based on their academic and industrial experience with middleware and enterprise application integration systems, they describe the fundamental concepts behind the notion of Web services and present them as the natural evolution of conventional middleware, necessary to meet the challenges of the Web and of B2B application integration.

Rather than providing a reference guide or a “how to write your first Web service” kind of book, they discuss the main objectives of Web services, the challenges that must be faced to achieve them, and the opportunities that this novel technology provides. Established, as well as recently proposed, standards and techniques (e.g., WSDL, UDDI, SOAP, WS-Coordination, WS-Transactions, and BPEL), are then examined in the context of this discussion in order to emphasize their scope, benefits, and shortcomings. Thus, the book is ideally suited both for professionals considering the development of application integration solutions and for research and students interesting in understanding and contributing to the evolution of enterprise application technologies.

SOA und WebServices

Product Description

Service-orientierte Architektur (SOA) ist ein aktuelles Schlagwort, das nicht nur im Bereich der Softwaretechnik sondern auch im Unternehmens-Management auf sehr viel Interesse gestoßen ist. Bei der Wahl der Strategie zur Modernisierung von IT-Landschaften fällt die Entscheidung häufig zugunsten dieses neuartigen Architekturmodells.Der Kerngedanke von SOA besteht darin, IT-Funktionalitäten in einzelne, geschäftsorientierte Serviceblöcke aufzuspalten und damit komplexe Strukturen aufzulösen. Dem Leser werden einerseits die allgemeinen Grundlagen der Serviceorientierung vermittelt und andererseits die technologischen Konzepte und Standards zur praktischen Umsetzung Service-orientierter Architekturen unter Verwendung von WebServices vorgestellt. Der Fokus liegt dabei auf der Fragestellung, in wie weit WebServices zur Implementierung geeignet sind. Ergänzend wird die Orchestrierung von Services zu einem Prozess mittels der Prozessbeschreibungssprache WS-BPEL beschrieben und auf organisatorische Vorgehensmethoden im Rahmen der SOA-Governance eingegangen.

Meta workflows as a control and coordination mechanism for exception handling in workflow systems

Product Description
This digital document is a journal article from Decision Support Systems, published by Elsevier in 2005. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser.

Description:
A higher level control and coordination mechanism is required for exception handling in workflow systems. This paper describes such a framework based on events, states, and a new kind of process called a meta workflow. Meta workflows have five kinds of meta activities and facilitate control over base workflows. We describe the framework and illustrate it with examples to show its features. The paper gives an architecture for incorporating it into existing workflows and also provides a formal semantics of execution. This framework can be used in Web services, supply chains, and inter-organizational applications where coordination requirements are complex, and flexible and adaptable workflows are needed. It is also useful for handling not just failure recovery but also various kinds of special situations, which arise frequently in web-based applications.

Web Services and Formal Methods: 4th International Workshop, WS-FM 2007, Brisbane, Australia, September 28-29, 2007, Proceedings

April 28, 2010 by BPELresource.com Leave a Comment

Product Description

This book constitutes the thoroughly refereed post-workshop proceedings of the 4th International Workshop on Web Services and Formal Methods, WS-FM 2007, held in Brisbane, Australia, in September 2007 in conjunction with the 5th International Conference on Business Process Management, BPM 2007.

The 9 revised full papers presented together with 2 invited papers were carefully reviewed and selected from 22 submissions. The papers address the application of formal methods and reasoning techniques to Web service technology, and formal theories inspired by developments in the field of Web services. The papers feature topics such as service-oriented analysis and design, formal approaches to enterprise modeling and business process modeling, model-driven development, testing, and analysis of Web services, Web services for business process management, security, performance and quality of Web services, Web service coordination and transactions, Web service ontologies and semantic description, goal-driven discovery and composition of Web services, complex event processing in service-oriented architectures, as well as semi-structured data management and XML technology.

BPEL-Tools im Vergleich: Open Source-BPEL-Tools und Oracle SOA Suite

April 28, 2010 by BPELresource.com Leave a Comment

Product Description
Schon seit einiger Zeit sind die Probleme der Softwareentwicklung wie zunehmende Komplexität und Heterogenität sowie fehlende Flexibilität bekannt. Einen viel versprechenden Ansatz in Bezug auf die beschriebenen Probleme stellt die Service-orientierte Architektur (SOA) dar. Auch IT-Trends wie das steigende Interesse an Prozessorientierung und Schwerpunkverlagerung von Anwendungsprogrammierung zu Anwendungsintegration fließen hier ein. Eine aussichtsreiche Lösung im Kontext prozessorientierter Softwareentwicklung basierend auf einer SOA ist die Business Process Execution Language (BPEL). Anatoliy Babiychuk erläutert in seinem Buch ausführlich die Grundlagen des Workflow-Managements und der SOA. Nachfolgend werden die BPEL-Konzepte vorgestellt. Auch dem zunehmenden Interesse an Open Source wird in diesem Buch Rechnung getragen. Eine Übersicht über die vorhandenen Open Source-Tools und ein Vergleich des am weitesten entwickelten Open Source-BPEL-Tools mit einem kommerziellen Werkzeug (Oracle Soa Suite) bilden die Schwerpunkte dieser Arbeit. Abschließend werden auch Migrationsmöglichkeiten von BPEL-Prozessen analysiert. Das Buch richtet sich an IT-Experten und interessierte Studenten.
