Oracle SOA Suite Developer's Guide

By: Antony Reynolds, Matt Wright

Overview of this book

<p>We are moving towards a standards-based Service-Oriented Architecture (SOA), where IT infrastructure is continuously adapted to keep up with the pace of business change. Oracle is at the forefront of this vision, with the Oracle SOA Suite providing the most comprehensive, proven, and integrated tool kit for building SOA based applications.<br /><br />Developers and Architects using the Oracle SOA Suite, whether working on integration projects, building composite applications, or specializing in implementations of Oracle Applications, need a hands-on guide on how best to harness and apply this technology. <br /><br />This book will guide you on using and applying the Oracle SOA Suite to solve real-world problems, enabling you to quickly learn and master the technology and its applications.<br /><br />The initial section of the book is aimed at providing you with a detailed hands-on tutorial to each of the core components that make up the Oracle SOA Suite; namely the Oracle Service Bus, BPEL Process Manager, Human Workflow, Business Rules, and Business Activity Monitoring. Once you are familiar with the various pieces of the SOA Suite and what they do, the next question will typically be: "What is the best way to combine / use all of these different components to implement a real-world SOA solution?"<br /><br />Answering this question is the goal of the next section. Using a working example of an online auction site (oBay), it leads you through key SOA design considerations in implementing a robust solution that is designed for change. Though the examples in the book are based on Oracle SOA Suite 10.1.3.4 the book will still be extremely useful for anyone using 11g.<br /><br />The final section addresses non-functional considerations and covers the packaging, deployment, and testing of SOA applications; it then details how to use Web Service Manager to secure and administer SOA applications.</p>

Phil McLaughlin has 20 years of early adopter experience with the technologies associated with SOA, working with architectural models such as object orientation before they were mainstream. In the late 1980s and early 1990s this was largely with the Smalltalk programming language and associated tools but he was asked to investigate and teach Java in 1997. Since then, he has maintained his interest in the development of distributed composite applications intially with CORBA, then J2EE and more recently SOA itself.

Phil's experience of SOA spans the theoretical and practical, having been a senior lecturer in academia until 1997 specializing in object oriented software (which could reasonably be argued as providing the foundations of the SOA architectural model), and how to transfer the requisite skills to developers often struggling with new and different architectural paradigms. Since 1997, he has worked in a number of specialist consultancies covering topics such as analysis and design methods, development and implementation from the OO/SOA perspective.

Phil Joined Oracle Corporation (UK) in 2002 when Oracle acquired the TopLink persistence management framework from WebGain and since then has specialized in working with Partners/System Integrators to educate them on best practice around the use of Oracle Java technology and more recently the Oracle SOA Suite. Phil currently holds the position of Master Principal Sales Consultant in the UK SOA pre-sales team where he provides initial advice and solution mapping to customers and partners about Oracle's SOA offerings.

Phil has worked with both authors for a number of years and is very pleased that thay have decided to share their wealth of knowledge and practical experience with the wider community. For anyone working with Oracle SOA suite, this is a 'must have' book.
