Book Description
"This book introduces the fundamentals of software contracts and illustrates how Design by Contract contributes to the optimal use of design patterns in a quality-oriented software engineering process. The Design by Contract approach to software construction provides a methodological guideline for building systems that are robust, modular, and simple." "Readers will find value in the book's overview of the Object Constraint Language, a precise modeling language that allows Design by Contract to be used with the industry standard Unified Modeling Language (UML). Although written in Eiffel, this book makes an excellent companion for developers who are using languages such as Java and UML. Throughout the book the authors discuss specific implementation issues and provide complete, ready-to-be-compiled examples of the use of each pattern." "They introduce design patterns and Design by Contract in the context of software engineering, and show how these tools are used to guide and document system design."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
The Ultimate Guide for Designing and Governing Web Service Contracts For Web services to succeed as part of SOA, they require balanced, effective technical contracts that enable services to be evolved and repeatedly reused for years to come. Now, a team of industry experts presents the first end-to-end guide to designing and governing Web service contracts. Writing for developers, architects, governance specialists, and other IT professionals, the authors cover the following areas: Understanding Web Service Contract Technologies Initial chapters and ongoing supplementary content help even the most inexperienced professional get up to speed on how all of the different technologies and design considerations relate to the creation of Web service contracts. For example, a visual anatomy of a Web service contract documented from logical and physical perspectives is provided, along with a chapter dedicated to describing namespaces in plain English. The book is further equipped with numerous case study examples and many illustrations. Fundamental and Advanced WSDL Tutorial coverage of WSDL 1.1 and 2.0 and detailed descriptions of their differences is followed by numerous advanced WSDL topics and design techniques, including extreme loose coupling, modularization options, use of extensibility elements, asynchrony, message dispatch, service instance identification, non-SOAP HTTP binding, and WS-BPEL extensions. Also explained is how WSDL definitions are shaped by key SOA design patterns. Fundamental and Advanced XML Schema XML Schema basics are covered within the context of Web services and SOA, after which advanced XML Schema chapters delve into a variety of specialized message design considerations and techniques, including the use of wildcards, reusability of schemas and schema fragments, type inheritance and composition, CRUD-style message design, and combining industry and custom schemas. Fundamental and Advanced WS-Policy Topics, such as Policy Expression Structure, Composite Policies, Operator Composition Rules, and Policy Attachment establish a foundation upon which more advanced topics, such as policy reusability and centralization, nested, parameterized, and ignorable assertions are covered, along with an exploration of creating concurrent policy-enabled contracts and designing custom policy assertions and vocabularies. Fundamental Message Design with SOAP A broad range of message design-related topics are covered, including SOAP message structures, SOAP nodes and roles, SOAP faults, designing custom SOAP headers and working with industry-standard SOAP headers. Advanced Message Design with WS-Addressing The art of message design is taken to a new level with in-depth descriptions of WS-Addressing endpoint references (EPRs) and MAP headers and an exploration of how they are applied via SOA design patterns. Also covered are WSDL binding considerations, related MEP rules, WS-Addressing policy assertions, and detailed coverage of how WS-Addressing relates to SOAP Action values. Advanced Message Design with MTOM, and SwA Developing SOAP messages capable of transporting large documents or binary content is explored with a documentation of the MTOM packaging and serialization framework (including MTOM-related policy assertions), together with the SOAP with Attachments (SwA) standard and the related WS-I Attachments Profile. Versioning Techniques and Strategies Fundamental versioning theory starts off a series of chapters that dive into a variety of versioning techniques based on proven SOA design patterns including backward and forward compatibility, version identification strategies, service termination, policy versioning, validation by projection, concurrency control, partial understanding, and versioning with and without wildcards. Web Service Contracts and SOA The constant focus of this book is on the design and versioning of Web service contracts in support of SOA and service-orientation. Relevant SOA design principles and design patterns are periodically discussed to demonstrate how specific Web service technologies can be applied and further optimized. Furthermore, several of the advanced chapters provide expert techniques for designing Web service contracts while taking SOA governance considerations into account. About the Web Sites www.soabooks.com supplements this book with a variety of resources, including a diagram symbol legend, glossary, supplementary articles, and source code available for download. www.soaspecs.com provides further support by establishing a descriptive portal to XML and Web services specifications referenced in all of Erl's Service-Oriented Architecture books.

Book Description
The management of telecommunications networks and services is one of the most challenging of software endeavors—partly because of the size and the distributed nature of networks; partly because of the convergence of communications techno- gies; but mainly because of sheer complexity and diversity of networks and services. The TM Forum s Solutions Frameworks (NGOSS) help address these challenges by providing a framework for the development of management applications—those software applications that provide the building blocks for management solutions. The members of the TM Forum have elaborated many parts of NGOSS to make it practical—including in the area of information modeling, process analysis, and c- tract de?nition. This book further elaborates NGOSS by examining the challenging area of interface design. One of the costs of deploying a new service is the cost of integrating all the necessary applications into an effective software solution to manage the service. This cost has been dubbed the “integration tax” and can turn out to be ?ve times the capital cost of procuring the management software in the ?rst place. From their long experience of the design and standardization of management applications, the authors have extracted a core set of design patterns for the dev- opment of effective and consistent interfaces to management applications. Adopting these patterns across the industry could reduce the learning curve for software - velopers and allow service providers and systems integrators to rapidly and reliably deploy management solutions and thereby markedly reduce the integration tax.
