"This book combines concepts from systems theory, model driven software engineering, and ontologies for software engineering into a systematic method for engineering service oriented systems"--Provided by publisher.

Service-Oriented Computing is a paradigm for developing and providing software that can address many IT challenges, ranging from integrating legacy systems to building new, massively distributed, interoperable, evaluable systems and applications. The widespread use of SOC demonstrates the practical benefits of this approach. Furthermore it raises the standard for reliability, security, and performance for IT providers, system integrators, and software developers. This book documents the main results of Sensoria, an Integrated Project funded by the European Commission in the period 2005-2010. The book presents, as Sensoria's essence, a novel, coherent, and comprehensive approach to the design, formal analysis, automated deployment, and reengineering of service-oriented applications. Following a motivating introduction, the 32 chapters are organized in the following topical parts: modeling in service-oriented architectures; calculi for service-oriented computing; negotiation, planning, and reconfiguration; qualitative analysis techniques for SOC; quantitative analysis techniques for SOC; model-driven development and reverse engineering for service-oriented systems; and case studies and patterns.

An integral element of software engineering is model engineering. They both endeavor to minimize cost, time, and risks with quality software. As such, model engineering is a highly useful field that demands in-depth research on the most current approaches and techniques. Only by understanding the most up-to-date research can these methods reach their fullest potential. Advancements in Model-Driven Architecture in Software Engineering is an essential publication that prepares readers to exercise modeling and model transformation and covers state-of-the-art research and developments on various approaches for methodologies and platforms of model-driven architecture, applications and software development of model-driven architecture, modeling languages, and modeling tools. Highlighting a broad range of topics including cloud computing, service-oriented architectures, and modeling languages, this book is ideally designed for engineers, programmers, software designers, entrepreneurs, researchers, academicians, and students.

As software systems are pervasive and play an important role in everyday life, the users are becoming more and more demanding. They mainly require more reliable systems that automatically adapt to different use cases. To satisfy these requirements, technical frameworks and design methods, upon which the systems development is based, must meet specific objectives mainly modularity, flexibility, and consistency. Service-Oriented Architecture (SOA) is a paradigm that offers mechanisms to increase the software flexibility and reduce development costs by enabling service orchestration and choreography. SOA promises also reliability through the use of services contracts as an agreement between the service provider and consumer. Model-driven SOA is a novel and promising approach that strengthens SOA with Model-Driven Engineering (MDE) technics that ease the specification, development, and verification of Service-Oriented Applications by applying abstraction and automation principles. Despite the progress to integrate MDE to SOA, there are still some challenging problems to be solved: (1) Rigorous verification of SOA system specifications. This is a challenging problem because to model SOA systems designers need more than one viewpoint, each of which captures a specific concern of the system. These viewpoints are meant to be semantically consistent with each other. This problem is called horizontal consistency checking and it is an important step to reduce inconsistencies in SOA models before transforming them into other forms (code generation, test cases derivation, etc.). (2) Transformation of systems specifications into executable artifacts. Despite the maturity of SOA, the transformation of system specifications into executable artifacts is usually manual, fastidious and error-prone. The transformation of services choreographies into executable orchestrations particularly remains a problem because of the necessity to take into account critical aspects of distributed systems such as asynchrony and concurrency when executing centralized orchestrations. (3) Runtime verification. Even after verifying Horizontal consistency at design time, there could be unexpected and unspecified data interactions that are unknown during design-time. For this reason, we still need consistency verification at runtime to handle such unforeseen events. This problem is called Vertical consistency checking. This thesis work proposes a Model-driven SOA approach to address the above-mentioned challenges. This approach includes a two-step model-driven methodology to horizontally and vertically verify the consistency of SOA systems specifications described using the SoaML standard from the Object Management Group (OMG). The horizontal consistency checking problem, which is the first challenge, is solved by means of static analysis of the system specification at the design level. The second challenge is solved by specifying the transformation from a choreography specification model to an executable orchestration implementing the choreography logic. Our transformation takes into consideration the asynchronous nature of the communications between distributed services. The vertical consistency checking problem, which is the third challenge, is solved by our approach thanks to offline analysis that allows consistency verification between both design and runtime levels. The entire methodological proposal was implemented as an extension to the open source UML modeling tool Papyrus.

Current IT developments like component-based development and Web services have emerged as effective ways of building complex enterprise-scale information systems and providing enterprise application integration. To aid this process, platforms such as .NET and WebSphere have become standards in web-based systems development. However, there are still a lot of issues that need to be addressed before service-oriented software engineering (SOSE) becomes a prominent and widely accepted paradigm for enterprise information systems development and integration. This book provides a comprehensive view of SOSE through a number of different perspectives. Some of those perspectives include: service-based concepts, modeling and documentation, service discovery and composition, service-oriented architecture, model-driven development of service-oriented applications, service security and service-orientation in mobile settings. The book provides readers with an in-depth knowledge of the main challenges and practices in the exciting, new world of service-oriented software engineering. Addressing both technical and organizational aspects of this new field, it offers a balance making it valuable to a variety of readers, including IT architects, developers, managers, and analysts.

Design and Implementation of service-oriented architectures imposes a huge number of research questions from the fields of software engineering, system analysis and modeling, adaptability, and application integration. Component orientation and web services are two approaches for design and realization of complex web-based system. Both approaches allow for dynamic application adaptation as well as integration of enterprise application. Commonly used technologies, such as J2EE and .NET, form de facto standards for the realization of complex distributed systems. Evolution of component systems has lead to web services and service-based architectures. This has been manifested in a multitude of industry standards and initiatives such as XML, WSDL UDDI, SOAP, etc. All these achievements lead to a new and promising paradigm in IT systems engineering which proposes to design complex software solutions as collaboration of contractually defined software services. Service-Oriented Systems Engineering represents a symbiosis of best practices in object-orientation, component-based development, distributed computing, and business process management. It provides integration of business and IT concerns. The annual Ph.D. Retreat of the Research School provides each member the opportunity to present his/her current state of their research and to give an outline of a prospective Ph.D. thesis. Due to the interdisciplinary structure of the Research Scholl, this technical report covers a wide range of research topics. These include but are not limited to: Self-Adaptive Service-Oriented Systems, Operating System Support for Service-Oriented Systems, Architecture and Modeling of Service-Oriented Systems, Adaptive Process Management, Services Composition and Workflow Planning, Security Engineering of Service-Based IT Systems, Quantitative Analysis and Optimization of Service-Oriented Systems, Service-Oriented Systems in 3D Computer Graphics sowie Service-Oriented Geoinformatics.

This textbook presents a proven, mature Model-Based Systems Engineering (MBSE) methodology that has delivered success in a wide range of system and enterprise programs. The authors introduce MBSE as the state of the practice in the vital Systems Engineering discipline that manages complexity and integrates technologies and design approaches to achieve effective, affordable, and balanced system solutions to the needs of a customer organization and its personnel. The book begins with a summary of the background and nature of MBSE. It summarizes the theory behind Object-Oriented Design applied to complex system architectures. It then walks through the phases of the MBSE methodology, using system examples to illustrate key points. Subsequent chapters broaden the application of MBSE in Service-Oriented Architectures (SOA), real-time systems, cybersecurity, networked enterprises, system simulations, and prototyping. The vital subject of system and architecture governance completes the discussion. The book features exercises at the end of each chapter intended to help readers/students focus on key points, as well as extensive appendices that furnish additional detail in particular areas. The self-contained text is ideal for students in a range of courses in systems architecture and MBSE as well as for practitioners seeking a highly practical presentation of MBSE principles and techniques.
