Transition between process models (BPMN) and service models (WS-BPEL and other standards): A systematic review

BPMN and BPEL have become de facto standards for modeling of business processes and imple-mentation of business processes via Web services. There is a quintessential problem of discrep-ancy between these two approaches as they are applied in different phases of lifecycle and theirfundamental concepts are different — BPMN is a graph based language while BPEL is basicallya block-based programming language. This paper shows basic concepts and gives an overviewof research and ideas which emerged during last two years, presents state of the art and possiblefuture research directions. Systematic literature review was performed and critical review wasgiven regarding the potential of the given solutions

Virtual learning process environment (VLPE): a BPM-based learning process management architecture

E-learning systems have significantly impacted the way that learning takes place within universities, particularly in providing self-learning support and flexibility of course delivery. Virtual Learning Environments help facilitate the management of educational courses for students, in particular by assisting course designers and thriving in the management of the learning itself. Current literature has shown that pedagogical modelling and learning process management facilitation are inadequate. In particular, quantitative information on the process of learning that is needed to perform real time or reflective monitoring and statistical analysis of students’ learning processes performance is deficient. Therefore, for a course designer, pedagogical evaluation and reform decisions can be difficult. This thesis presents an alternative e-learning systems architecture - Virtual Learning Process Environment (VLPE) - that uses the Business Process Management (BPM) conceptual framework to design an architecture that addresses the critical quantitative learning process information gaps associated with the conventional VLE frameworks. Within VLPE, course designers can model desired education pedagogies in the form of learning process workflows using an intuitive graphical flow diagram user-interface. Automated agents associated with BPM frameworks are employed to capture quantitative learning information from the learning process workflow. Consequently, course designers are able to monitor, analyse and re-evaluate in real time the effectiveness of their chosen pedagogy using live interactive learning process dashboards. Once a course delivery is complete the collated quantitative information can also be used to make major revisions to pedagogy design for the next iteration of the course. An additional contribution of this work is that this new architecture facilitates individual students in monitoring and analysing their own learning performances in comparison to their peers in a real time anonymous manner through a personal analytics learning process dashboard. A case scenario of the quantitative statistical analysis of a cohort of learners (10 participants in size) is presented. The analytical results of their learning processes, performances and progressions on a short Mathematics course over a five-week period are also presented in order to demonstrate that the proposed framework can significantly help to advance learning analytics and the visualisation of real time learning data

An Integrated Methodology for Creating Composed Web/Grid Services

This thesis presents an approach to design, specify, validate, verify, implement, and evaluate composed web/grid services. Web and grid services can be composed to create new services with complex behaviours. The BPEL (Business Process Execution Language) standard was created to enable the orchestration of web services, but there have also been investigation of its use for grid services. BPEL specifies the implementation of service composition but has no formal semantics; implementations are in practice checked by testing. Formal methods are used in general to define an abstract model of system behaviour that allows simulation and reasoning about properties. The approach can detect and reduce potentially costly errors at design time. CRESS (Communication Representation Employing Systematic Specification) is a domainindependent, graphical, abstract notation, and integrated toolset for developing composite web service. The original version of CRESS had automated support for formal specification in LOTOS (Language Of Temporal Ordering Specification), executing formal validation with MUSTARD (Multiple-Use Scenario Testing and Refusal Description), and implementing in BPEL4WS as the early version of BPEL standard. This thesis work has extended CRESS and its integrated tools to design, specify, validate, verify, implement, and evaluate composed web/grid services. The work has extended the CRESS notation to support a wider range of service compositions, and has applied it to grid services as a new domain. The thesis presents two new tools, CLOVE (CRESS Language-Oriented Verification Environment) and MINT (MUSTARD Interpreter), to respectively support formal verification and implementation testing. New work has also extended CRESS to automate implementation of composed services using the more recent BPEL standard WS-BPEL 2.0

The CHORCH Approach: How to Model B2Bi Choreographies for Orchestration Execution

The establishment and implementation of cross-organizational business processes is an implication of today's market pressure for efficiency gains. In this context, Business-To-Business integration (B2Bi) focuses on the information integration aspects of business processes. A core task of B2Bi is providing adequate models that capture the message exchanges between integration partners. Following the terminology used in the SOA domain, such models will be called choreographies in the context of this work. Despite the enormous economic importance of B2Bi, existing choreography languages fall short of fulfilling all relevant requirements of B2Bi scenarios. Dedicated B2Bi choreography standards allow for inconsistent outcomes of basic interactions and do not provide unambiguous semantics for advanced interaction models. In contrast to this, more formal or technical choreography languages may provide unambiguous modeling semantics, but do not offer B2Bi domain concepts or an adequate level of abstraction. Defining valid and complete B2Bi choreography models becomes a challenging task in the face of these shortcomings. At the same time, invalid or underspecified choreography definitions are particularly costly considering the organizational setting of B2Bi scenarios. Models are not only needed to bridge the typical gap between business and IT, but also as negotiation means among the business users of the integration partners on the one hand and among the IT experts of the integration partners on the other. Misunderstandings between any two negotiation partners potentially affect the agreements between all other negotiation partners. The CHORCH approach offers tailored support for B2Bi by combining the strengths of both dedicated B2Bi standards and formal rigor. As choreography specification format, the ebXML Business Process Specification Schema (ebBP) standard is used. ebBP provides dedicated B2Bi domain concepts such as so-called BusinessTransactions (BTs) that abstractly specify the exchange of a request business document and an optional response business document. In addition, ebBP provides a format for specifying the sequence of BT executions for capturing complex interaction scenarios. CHORCH improves the offering of ebBP in several ways. Firstly, the execution model of BTs which allows for inconsistent outcomes among the integration partners is redefined such that only consistent outcomes are possible. Secondly, two binary choreography styles are defined as B2Bi implementation contract format in order to streamline implementation projects. Both choreography styles are formalized and provided with a formal execution semantics for ensuring unambiguity. In addition, validity criteria are defined that ensure implementability using BPEL-based orchestrations. Thirdly, the analysis of the synchronization dependencies of complex B2Bi scenarios is supported by means of a multi-party choreography style combined with an analysis framework. This choreography style also is formalized and standard state machine semantics are reused in order to ensure unambiguity. Moreover, validity criteria are defined that allow for analyzing corresponding models for typical multi-party choreography issues. Altogether, CHORCH provides choreography styles that are B2Bi adequate, simple, unambiguous, and implementable. The choreography styles are B2Bi adequate in providing B2Bi domain concepts, in abstracting from low-level implementation details and in covering the majority of real-world B2Bi scenarios. Simplicity is fostered by using state machines as underlying specification paradigm. This allows for thinking in the states of a B2Bi scenario and for simple control flow structures. Unambiguity is provided by formal execution semantics whereas implementability (for the binary choreography styles) is ensured by providing mapping rules to BPEL-based implementations. The validation of CHORCH's choreography styles is performed in a twofold way. Firstly, the implementation of the binary choreography styles based on Web Services and BPEL technology is demonstrated which proves implementability using relatively low-cost technologies. Moreover, the analysis algorithms for the multi-party choreography styles are validated using a Java-based prototype. Secondly, an abstract visualization of the choreography styles based on BPMN is provided that abstracts from the technicalities of the ebBP standard. This proves the amenability of CHORCH to development methods that start out with visual models. CHORCH defines how to use BPMN choreographies for the purpose of B2Bi choreography modeling and translates the formal rules for choreography validity into simple composition rules that demonstrate valid ways of connecting the respective modeling constructs. In summary, CHORCH allows integration partners to start out with a high-level visual model of their interactions in BPMN that identifies the types and sequences of the BusinessTransactions to be used. For multi-party choreographies, a framework for analyzing synchronization dependencies then is available. For binary choreographies, an ebBP refinement can be derived that fills in the technical parameters that are needed for deriving the implementation. Finally, Web Services and BPEL based implementations can be generated. Thus, CHORCH allows for stepwise closing the semantic gap between the information perspective of business process models and the corresponding implementations. It is noteworthy that CHORCH uses international standards throughout all relevant layers, i.e., BPMN, ebBP, Web Services and BPEL, which helps in bridging the heterogeneous IT landscapes of B2Bi partners. In addition, the adoption of core CHORCH deliverables as international standards of the RosettaNet community give testament to the practical relevance and promise dissemination throughout the B2Bi community.Betriebsübergreifende Geschäftsprozessintegration ist eine logische Konsequenz allgegenwärtigen Wettbewerbsdrucks. In diesem Kontext fokussiert Business-To-Business integration (B2Bi) auf die Informationsaustausche zwischen Unternehmen. Eine B2Bi-Kernanforderung ist die Bereitstellung adäquater Modelle zur Spezifikation der Nachrichtenaustausche zwischen Integrationspartnern. Diese werden im Rahmen dieser Arbeit in Anlehnung an Service-orientierte Architekturen (SOA)-Terminologie Choreographien genannt. Bestehende Choreographiesprachen decken die Anforderungen an B2Bi-Choreographien nicht vollständig ab. Dedizierte B2Bi-Choreographiestandards definieren inkonsistente Austauschprozeduren für grundlegende Interaktionen und nur unvollständige Semantiken für fortgeschrittene Interaktionen. Formale oder Technik-getriebene Choreographiesprachen bieten die benötigte Präzision, lassen aber Domänenkonzepte vermissen oder operieren auf einer niedrigen Abstraktionsebene. Angesichts solcher Mängel wird die Spezifikation valider und vollständiger B2Bi-Choreographien zu einer echten Herausforderung. Gleichzeitig sind mangelhafte Choreographiemodelle gerade im B2Bi-Bereich besonders problematisch, da diese nicht nur zwischen Fach- und IT-Abteilung, sondern auch über Unternehmensgrenzen hinweg eingesetzt werden. Der CHORCH-Ansatz schafft an dieser Stelle mittels maßgeschneiderter Choreographien Abhilfe, welche die Vorteile von B2Bi-Choreographien und von formalen Ansätzen kombinieren. Als Ausgangspunkt wird das ebXML Business Process Specification Schema (ebBP) verwendet, das als B2Bi-Choreographiestandard Domänenkonzepte wie zum Beispiel sogenannte BusinessTransactions (BTs) bietet. Eine BT ist der Basisbaustein von B2Bi-Choreographien und spezifiziert den Austausch eines Geschäftsdokuments sowie eines optionalen Antwortdokuments. Darüber hinaus bietet ebBP ein Format zur Spezifikation von BT-Kompositionen zur Unterstützung komplexer Interaktionen. CHORCH erweitert ebBP wie folgt. Erstens, das Ausführungsmodell für BTs wird neu definiert, um inkonsistente Ergebniszustände zu eliminieren. Zweitens, für Entwicklungsprojekte werden zwei binäre Choreographieklassen definiert, die als B2Bi-Implementierungskontrakt dienen sollen. Die Formalisierung beider Klassen sowie formale operationale Semantiken gewährleisten Eindeutigkeit, während Validitätskriterien die Ausführbarkeit entsprechender Modelle mittels BPEL-basierter Orchestrationen garantieren. Drittens, zur Analyse der Synchronisationsbeziehungen komplexer B2Bi-Szenarien wird eine Multi-Party-Choreographieklasse nebst Analyseframework definiert. Wiederum wird für diese Klasse eine Formalisierung definiert, die mittels Standard-Zustandsautomatensemantik Eindeutigkeit gewährleistet. Ferner garantieren Validitätskriterien die Anwendbarkeit der definierten Analysealgorithmen. Insgesamt bieten die Choreographieklassen des CHORCH-Ansatzes ein B2Bi-adäquates, einfaches, eindeutiges und implementierbares Modell der Nachrichtenaustausche zwischen B2Bi-Partnern. B2Bi-Adäquatheit wird durch Verwendung von B2Bi-Domänenkonzepten, Abstraktion von rein technischen Kommunikationsdetails und Abdeckung der meisten praktisch relevanten B2Bi-Szenarien gewährleistet. Einfachheit ist ein Ausfluss der Verwendung eines Zustandsmaschinen-basierten Modellierungsparadigmas, das die Definition des Interaktionsfortschritts in Form von Zuständen sowie einfache Kontrollflussstrukturen ermöglicht. Eindeutigkeit wird durch die Verwendung formaler Semantiken garantiert, während Implementierbarkeit (für die beiden binären Choreographieklassen) durch Angabe von Mapping-Regeln auf BPEL-Orchestrationen sichergestellt wird. Die Validierung der CHORCH-Choreographieklassen erfolgt in zweierlei Hinsicht. Erstens, die Implementierbarkeit der binären Choreographieklassen mit Hilfe von Web Services und BPEL wird durch die Definition entsprechender Mappingregeln belegt. Weiterhin wird das Analyseframework der Multi-Party-Choreographieklasse als Java-Prototyp implementiert. Zweitens, für alle Choreographieklassen wird eine abstrakte Visualisierung auf BPMN-Basis definiert, die von diversen technischen Parametern des ebBP-Formats abstrahiert. Damit wird die Integrierbarkeit der CHORCH-Choreographieklassen in Entwicklungsansätze, die ein visuelles Modell als Ausgangspunkt vorsehen, belegt. CHORCH definiert, wie sogenannte BPMN-Choreographien zum Zweck der B2Bi-Choreographiemodellierung zu verwenden sind und übersetzt die Validitätskriterien der CHORCH-Choreographieklassen in einfache Modell-Kompositionsregeln. In seiner Gesamtheit bietet CHORCH somit einen Ansatz, mit Hilfe dessen B2Bi-Partner zunächst die Typen und zulässigen Reihenfolgen ihrer Geschäftsdokumentaustausche auf Basis eines abstrakten visuellen BPMN-Modells identifizieren können. Im Fall von Multi-Party-Choreographien steht dann ein Framework zur Analyse der Synchronisationsbeziehungen zwischen den Integrationspartnern zur Verfügung. Im Fall von binären Choreographien können ebBP-Verfeinerungen abgeleitet werden, welche die Modelle um technische Parameter anreichern, die zur Ableitung einer Implementierung benötigt werden. Diese ebBP-Modelle sind in Web Services- und BPEL-basierte Implementierungen übersetzbar. Damit erlaubt CHORCH die schrittweise Überbrückung der semantischen Lücke zwischen der Informationsaustauschperspektive von Geschäftsprozessmodellen und den zugehörigen Implementierungen. Ein beachtenswerter Aspekt des CHORCH-Ansatzes ist die Verwendung einschlägiger internationaler Standards auf allen Abstraktionsebenen, im Einzelnen BPMN, ebBP, Web Services und BPEL. Die Verwendung von Standards trägt dem heterogenen Umfeld von B2Bi-Szenarien Rechnung. Zusätzlich wurden Kernergebnisse des CHORCH-Ansatzes als internationale Standards der RosettaNet-B2Bi-Community veröffentlicht. Dies belegt die praktische Relevanz des Ansatzes und fördert die Verbreitung innerhalb der B2Bi-Community

A Reference Architecture for Service Lifecycle Management – Construction and Application to Designing and Analyzing IT Support

Service-orientation and the underlying concept of service-oriented architectures are a means to successfully address the need for flexibility and interoperability of software applications, which in turn leads to improved IT support of business processes. With a growing level of diffusion, sophistication and maturity, the number of services and interdependencies is gradually rising. This increasingly requires companies to implement a systematic management of services along their entire lifecycle. Service lifecycle management (SLM), i.e., the management of services from the initiating idea to their disposal, is becoming a crucial success factor. Not surprisingly, the academic and practice communities increasingly postulate comprehensive IT support for SLM to counteract the inherent complexity. The topic is still in its infancy, with no comprehensive models available that help evaluating and designing IT support in SLM. This thesis presents a reference architecture for SLM and applies it to the evaluation and designing of SLM IT support in companies. The artifact, which largely resulted from consortium research efforts, draws from an extensive analysis of existing SLM applications, case studies, focus group discussions, bilateral interviews and existing literature. Formal procedure models and a configuration terminology allow adapting and applying the reference architecture to a company’s individual setting. Corresponding usage examples prove its applicability and demonstrate the arising benefits within various SLM IT support design and evaluation tasks. A statistical analysis of the knowledge embodied within the reference data leads to novel, highly significant findings. For example, contemporary standard applications do not yet emphasize the lifecycle concept but rather tend to focus on small parts of the lifecycle, especially on service operation. This forces user companies either into a best-of-breed or a custom-development strategy if they are to implement integrated IT support for their SLM activities. SLM software vendors and internal software development units need to undergo a paradigm shift in order to better reflect the numerous interdependencies and increasing intertwining within services’ lifecycles. The SLM architecture is a first step towards achieving this goal.:Content Overview List of Figures....................................................................................... xi List of Tables ...................................................................................... xiv List of Abbreviations.......................................................................xviii 1 Introduction .................................................................................... 1 2 Foundations ................................................................................... 13 3 Architecture Structure and Strategy Layer .............................. 57 4 Process Layer ................................................................................ 75 5 Information Systems Layer ....................................................... 103 6 Architecture Application and Extension ................................. 137 7 Results, Evaluation and Outlook .............................................. 195 Appendix ..........................................................................................203 References .......................................................................................... 463 Curriculum Vitae.............................................................................. 498 Bibliographic Data............................................................................ 49
