Modeling Adaptable Business Service for Enterprise Collaboration

Cloud computing, a more recent computing paradigm, has evolved from a variety of legacy technologies that include Service oriented Architecture (SOA) and Web services besides several others. The software services in a cloud must be developed based on the service-oriented approach, in order to derive their full potential and benefits. Since, SOA inherently nurtures interoperability; it will enhance the integration and interaction among the cloud software services. Also, leveraging the Model Driven Architecture (MDA) approach to develop individual cloud software services will result in services that are more robust, flexible and agile in the wake of ever changing technologies. This paper is an attempt by the authors to lay emphasis on the convergence of Cloud computing, SOA and MDA in development of optimum business solutions.KeywordsCloud computingCloud SaaSService Oriented Architecture (SOA)Model-Driven Architecture (MDA)Computation Independent Model (CIM)Platform Independent Model (PIM)Platform Specific Model (PSM)Interoperability

The current approach to the design, maintenance, and governance of service-oriented architecture (SOA) solutions has focused primarily on flow-driven assembly and orchestration of reusable service components. The practical application of this approach in creating industry solutions has been limited, because flow-driven assembly and orchestration models are too rigid and static to accommodate complex, real-world business processes. Furthermore, the approach assumes a rich, easily configured library of reusable service components when in fact the development, maintenance, and governance of these libraries is difficult. An alternative approach pioneered by the IBM Research Division, model-driven business transformation (MDBT), uses a model-driven software synthesis technology to automatically generate production-quality business service components from high-level business process models. In this paper, we present the business entity life cycle analysis (BELA) technique for MDBT-based SOA solution realization and its integration into service-oriented modeling and architecture (SOMA), the end-to-end method from IBM for SOA application and solution development. BELA shifts the process-modeling paradigm from one that is centered on activities to one that is centered on entities. BELA teams process subject-matter experts with IT and data architects to identify and specify business entities and decompose business processes. Supporting synthesis tools then automatically generate the interacting business entity service components and their associated data stores and service interface definitions. We use a large-scale project as an example demonstrating the benefits of this innovation, which include an estimated 40 percent project cost reduction and an estimated 20 percent reduction in cycle time when compared with conventional SOA approaches.

Enterprise application integration makes data sharing easier, efficient and provides flexibility for organizations to seize opportunities and respond to stakeholder needs. Faculty of Mathematics and Natural Sciences (FMIPA) Tanjungpura University is an organization that wants to apply information technology effectively to support its business processes. Currently the application at FMIPA is built with different platforms and databases so that it cannot be integrated to share data between parts of the organization. FMIPA intends to build a service-oriented technology architecture to support the realization of organizational goals. SOA (Service Oriented Architecture) can be used as a framework for enterprise application integration. SOA adoption is often not as expected because organizations do not plan their processes comprehensively. It is necessary to measure the maturity level of the organization's SOA adoption so that the current state of the organization's SOA and future expectations can be found. ISO/IEC 16680 (OSIMM) is a method for measuring the SOA maturity level with 7 levels of maturity and 7 dimensions. To expedite the SOA adoption process in FMIPA, SOA maturity level was measured using ISO/IEC 16680. Based on measurements of the seven dimensions of SOA at ISO/IEC 16680, it was found that the current level of SOA adoption maturity (As-Is) at FMIPA Untan was at the level one (Silo), while the expected maturity level (To-Be) is level four (Service). Gap analysis then carried out related to the gap in maturity levels, and is followed by making recommendations dan roadmap for SOA adoption.

Enterprises continue to face the challenge of cost effective operations and thus, standardization and openness are becoming an imperative for operational efficiencies at a much higher business level than information systems and related IT infrastructure. Business processes have governed enterprise operational modeling for several decades and have provided the basis for many business transformation approaches. Business processes have thus become an early form of standardization and their continuous maturity has given rise to a very important outsourcing market that has helped companies produce substantial savings by T. Davenport (2005). However, there is a clear need for new ways of modeling enterprise operations that exploit deeper levels of industry-specific commonalities across companies, thus realizing further economies of scale while yielding more savings and enhanced resilience. This paper introduces the concept of business service-based modeling of companies and related ecosystems as an innovative approach for attaining these goals. The concept of is not new. Service oriented architectures (SOA), related Web services and other service standardization efforts are well-known today. However, the focus of existing service models is primarily integration of IT systems based on interoperability. These models, which are targeted towards solution implementers, do not adequately address the needs of higher level, business-oriented modeling within the context of a service-oriented operation and corresponding service-oriented ecosystems. Companies are beginning to recognize the importance of business-level service orientation as a pre-requisite to becoming competitive. For on demand interaction with their customers, suppliers, partners, and employees, companies are actively exploring what business services to provide and how to develop them rapidly in order to be responsive and grow margins. Hence, there is a need for proper operational modeling constructs and corresponding SW tools that support design, representation, and analysis of services that are required by service-oriented, on demand businesses. Business Services provide such a new paradigm for extended business-level standardization and componentization. In this paper, the concept of business services is introduced and illustrated with several examples. A new metamodel exposing the different aspects of company operations comprised by these business services were presented. Traditional functional modeling approaches including business processes will be related to business services

Marine environmental information is the main decision-making basis on ocean development, marine environmental protection and marine management. With the rapid development of ocean science technology and requirement of ocean application, human beings are more relay on the marine environmental information, and the requirement for the management and service on marine environmental information becomes higher and higher. SOA (Service Oriented Architecture) encapsulate information in the shape of service, now is the one of the most concernful themes in the IT field, and is the trend for marine data information construction. This article recommends the concept and technology of data warehouse, SOA and Web Service, does deep research on the traditional data warehouse architecture and the features of current marine heterogeneous data informatization, does analysis on the status and existing problems of marine data warehouse, and proposed a information integration architecture strategy based on SOA and marine environmental data warehouse.

Similar with definition of ‘service’, the term ‘service engineering’ (SE) can be broadly defined based on the context and the referring domain. This paper explores the evolutionary definition of SE, with later emphasis on IT/IS perspective. The paper begin with general definition of service and service engineering before elaborating IT perspectives on IT. A review on service orientation, Service Oriented Architecture (SOA) and Service Oriented Methodology (SOM) is also provided in the final part, before concluded with conclusion and suggested future work. In a more general perspective of Service Science, SE is defined as a process of developing newly specified business service, while in IT perspective SE alternately defined as applying service-orientation approach in an enterprise and its IT infrastructure, closely related with SOA approach. Therefore, to consolidate both perspectives, SE can be applied for designing specific business services, as the original definition, combined with bottom up, or meet-in-the-middle approach in the conception of software services during the analysis.

With the rapid development of information technology, the growth of heterogeneous Web data and the requirements of access to the Web of data also is growing. In view of this, a method of heterogeneous data integration based on SOA(Service-Oriented Architecture) is proposed. This method combines the technology of middleware and SOA design, using XML and Web services technologies, presents a framework of heterogeneous data integration based on SOA, and introduces the architecture of SOA data integration middleware. Experimental results show that this method reduces the coupling of heterogeneous data integration system effectively, and improves the scalability of the system.

With the advent of distributed technologies and related Integrated Development Environments (IDEs), business collaborations across the world irrespective of the platforms in which applications were built.The underlying technology is Web Services which is based on XML standard and the architecture is SOA (Service Oriented Architecture).Many SOA frameworks came in to existence.However, their primary focus is discovering, composition of services in order to make flexible service oriented distributed enterprise applications.Such systems without human expertise may be incomplete.To overcome this problem, this paper proposes techniques to collaborate services based software with human experts thus forming a knowledgeintensive and people centric web besides sharing and reusing software components in distributed environment.To achieve this, we propose a flexible and adaptive approach which facilitates software services and humans to collaborate using Web Services and its important standards like SOAP (Simple Object Access Protocol), WSDL (Web Services Description Language) and UDDI (Universal Description Discovery Integration).This kind of human centric enterprise web has far reaching implications and it can attract the human experts to participate in rendering their best possible services.Interaction monitoring techniques that are adaptive thus realizing standards based people-centric systems.

Business Intelligence and Service Oriented Architecture – Improving IT Investments

Information Technology does not solve business problems. Rather, IT can be used as an enabler to meet goals, targets and position the organization in the minds of the customer. A Service Oriented Architecture (SOA) can enable higher level services from more primitive business processes. The result is a flexible, agile organization. However, in some cases, without a business model, an SOA can be implemented but the result is islands of incompatible services. In the era of data analytics, the evolution of business intelligence has assumed a more dominant role. Proponents argue that Business Intelligence subsumes SOA. Other practitioners argue that Business Intelligence (BI) and SOA are distinct from each other as each aims to deliver different perspectives to an organization. This chapter challenges this view by developing a framework where both SOA and BI are pivotal to delivering the business model. The analytics, business intelligence and data mining handshake with the SOA, allowing decision makers to plan, coordinate and control resources to meet the goals, targets and performance measures set for the organization. Business Intelligence and SOA need not operate on different levels for an organisation. In an era where companies are trying to go from barely surviving IT expenses towards developing an IT portfolio, the more options for technologies supporting asset data management, warehousing and mining to interact and co-exist are necessary. Putting aside arguments of Business Intelligence versus SOA, we propose that they can handshake and bring out the collaborative synergies to enable organizational decision making to address the competitive challenges in today’s global marketplace.KeywordsDecision support and optimization methods and toolsBusiness intelligenceSOA

Der Ausdruck Quality of Service (QoS) beschreibt die Güte eines erbrachten Dienstes. QoS beschreibt Eigenschaften wie Antwortzeit, Verfügbarkeit, den Grad der Nachrichten-Verschlüsselung oder den Durchsatz. QoS ist sowohl für Multi-Media Anwendungen (Audio- und Video-Übertragung) als auch für Geschäftsanwendungen wichtig. Die vorgelegte Arbeit konzentriert sich dabei auf das Feld der Geschäftsanwendungen. Solche Anwendungen arbeiten mit Transaktionen wie etwa dem Bestellen eines Produkts oder der Überweisung von Geld zwischen Konten. QoS Eigenschaften solcher Anwendungen sind beispielsweise die Anzahl an Transaktionen während eines Zeitintervalls, die maximale Anzahl gleichzeitig mit dem System arbeitender Nutzer, oder die zu erwartende Verfügbarkeit. Durch Middleware kann die Realisierung von Verteilung vor dem Programmierer verborgen werden. In einer idealen Welt würde Middleware dasselbe für QoS leisten. Das heißt, der Entwickler spezifiziert nur die gewünschte Dienstgüte und kümmert sich nicht darum, wie sie realisiert wird. Das ist so aber nicht möglich, denn die zu erbringende Dienstgüte hat massive Auswirkungen auf das Design einer Applikation. Daher muss QoS schon in der Design-Phase angegangen werden, was mit einer rein Middleware-gestützten Herangehensweise nicht möglich ist. Die vorgelegte Arbeit zeigt, wie dieses Problem durch einen modellgetriebenen Ansatz behoben werden kann. Die Entwicklung beginnt dann mit einem Plattform-unabhängigen Modell (PIM), welches das Verhalten und die QoS Eigenschaften der Applikation beschreibt. Dieses Modell wird automatisch durch eine Modell-Transformation in ein Plattform-spezifisches Modell (PSM) umgewandelt. Das PSM beschreibt das Design einer Implementierung für eine spezifische Plattform und berücksichtigt dabei die im PIM beschriebenen QoS-Eigenschaften. Um dieses Szenario in der Praxis anwenden zu können, müssen zwei Probleme gelöst werden: das Modellieren von QoS Eigenschaften und die Modell-Transformation. Gegenwärtig erfordert das Erstellen einer Modell-Transformation detailliertes Wissen über die Modellierungssprache und ihre Interna. Um das zu vereinfachen, wurde im Rahmen dieser Arbeit die visuelle Regelbasierte Transformationssprache Kafka entwickelt. Kafka und die zugehörigen Werkzeuge bauen auf Graphtransformations-Theorie auf. Kafka vereinfacht das Erstellen von Transformationen weil es auf der Notation des PIM und PSM aufbaut. Daher muss der Entwickler nichts von den Interna (etwa dem Meta-Modell) verstehen. Um PIMs von QoS-fähigen Applikationen zu erstellen, wurde die Modellierungssprache PIQML entwickelt, welche auf UML 2.0 Komponenten, Hierarchischen Nachrichten Sequenz Diagrammen (HMSCs) und einer neuen Meta-Modell Erweiterung für QoS Verträge basiert. Die vorgelegte Arbeit zeigt, wie PIQML Modelle auf verschiedene Zielplattformen (Programmiersprachen und Middleware Produkte) abgebildet werden können. Basierend auf PIQML und Kafka wurde das Werkzeug Kase entwickelt, welches das Editieren von PIQML Modellen (PIMs), UML Modellen (PSMs) und Kafka Transformationen integriert. Das Ergebnis ist eine integrierte Werkzeug-Kette für das modellgetriebene Entwickeln QoS-fähiger verteilter Applikationen.

Service Oriented Architecture (SOA) has been widely used during the past decade due to its ability to seamlessly integrate various applications developed using different technologies. Web services based on open standards are the most commonly used technology to realize an SOA. Business processes are executed by appropriate orchestration of various services from different departments that belong to a single organization or from multiple organizations. Security is an important quality attribute that has to be built into any application that is developed using SOA. XML is the underlying technology for Web Service Description Language (WSDL), SOAP protocol and Business Process Execution Language (BPEL). It is highly probable that an attacker could inject malicious information into these XML files to modify the flow of the business process. Further, SOAP was not designed with security in mind, it is possible to tamper the SOAP messages while they are in transit. There exist a number of such potential vulnerabilities which lead to possible security breach in the individual services. In an orchestrated business process, there are possibilities of more vulnerabilities. One of the existing tools namely WS-Attacker is only capable of testing the security of individual web services alone. In spite of the widespread usage of SOA, currently there is limited automatic tool support for testing the security provided by an entire SOA application involving service orchestration. In this context, this paper focuses on designing and implementing a plug-in for WS-Attacker to analyze a few security vulnerabilities present in SOA business processes.

The Service Oriented Architecture (SOA) is embraced in distributed and grid computing to produce high performance results for long time. SOA is likened by application programmers for its trademark characteristics of programmability, efficiency in heterogeneous conditions and fault-tolerance. It has worked well for high performance financial applications. but not for scientific applications which are too fine grained and communication intensive to be efficient on distributed environments. This paper argues that to make SOA model work well for those scientific applications, we need to reduce overhead costs associated with smaller task loads arising from finer granularity and increased communications in those applications. This paper proposes a data service to be used along with the existing compute services in SOA middlewares to enable inter-communication of finer tasks with out loosing SOA properties of programmability and efficiency under heterogeneity. This data service shall better enable high performance scientific computing of medium to fine grained scientific applications.

The e-commerce platform is developed by using service-oriented architecture (SOA). This system has advantages of loosely coupled, flexible, easy to use, scalable, reusable and so on. But the SOA environment has the characteristics of openness, divide and conquer and dynamic. These characteristics not only provide convenience for the damage behavior, such as tampering with message bodies, unauthorized access, but also make the security technology of user authority management, authentication and access control implementation more difficult. Security technology of traditional domain-oriented computing is difficult to adapt to the new features of service-oriented architecture, and the most urgent key problem for us to study is how to ensure that service-oriented architecture security. This article is mainly to design a implementation scheme of security access framework for SOA environment built based on Web Service technology. Which applied in e-commerce platform, so that the whole system with a high degree of security, good extensibility and integration.
