Service Oriented Architecture: An Integration Blueprint

Overview of this book

Service Oriented Architecture (SOA) refers to building systems that offer applications as a set of independent services that communicate and inter-operate with each other effectively. Such applications may originate from different vendor, platform, and programming language backgrounds, making successful integration a challenging task. This book enables you to integrate application systems effectively, using the Trivadis Integration Architecture Blueprint, which is supported by real-world scenarios in which this Integration Blueprint has proved a success.This book will enable you to grasp all of the intricacies of the Trivadis Architecture Blueprint, including detailed descriptions of each layer and component. It is a detailed theoretical guide that shows you how to implement your own integration architectures in practice, using the Trivadis Integration Architecture Blueprint. The main focus is on explaining and visualizing the blueprint, including comprehensive descriptions of all of its layers and components. It also covers the more basic features of integration concepts for less experienced specialists, as well as shedding light on the future of integration technologies, such as XTP and Grid Computing. You will learn about EII and EAI, OGSi, as well as base technologies related to the implementation of solutions based on the Blueprint, such as JCA, JBI, SCA and SDO.The book begins by covering fundamental integration for those less familiar with the concepts and terminology, and then dives deep into explaining the different architecture variants and the future of integration technologies. Base technologies like JCA and SCA will be explored along the way, and the structure of the Trivadis Integration Architecture Blueprint will be described in detail, as will the intricacies of each component and layer. Other content includes discovering and comparing traditional and modern SOA driven integration solutions, implementing transaction strategies and process modeling, and getting to grips with EDA developments in SOA. Finally, the book considers how to map software from vendors like Oracle and IBM to the blueprint in order to compare the solutions, and ultimately integrate your own projects successfully.

About the Authors


Transactions and transaction strategies play a central role in every architecture. A knowledge of the options available and the differences between them is essential when choosing suitable data access strategies. This section covers the aspects relating to integration. These include transactional systems, isolation levels, two-phase commit, and XA transactions.

  • Transactional systems: These allow for controlled "all-or-nothing" data manipulation.

  • Isolation levels: These levels coordinate data access by parallel transactions and, depending on the level, determine the visibility of the manipulated data. There are four different isolation levels:

    • serializable

    • repeatable read

    • read committed

    • read uncommitted

  • Two-phase commit: The two-phase commit is the algorithm on which transactions are based. It requires all the systems participating in a transaction to commit to the successful completion of the transaction.

  • XA transactions: An XA transaction is a standardized, global transaction...
