Résumé

A Service Oriented Architecture approach has many benefits for your applications, including flexibility, reusability, and increased revenue. You can exploit those benefits to the fullest by following this step-by-step tutorial for WPS and WESB.

Key Features Develop SOA applications using the WebSphere Process Server (WPS) and WebSphere Enterprise Service Bus (WESB) Analyze business requirements and rationalize your thoughts to see if an SOA approach is appropriate for your project Quickly build an SOA-based Order Management application by using some fundamental concepts and functions of WPS and WESB Do a top-down decomposition of the Order Management application to identify use cases, business processes, and services/components Book Description By adopting an SOA approach in Business Process Management (BPM), you can make your application flexible, reusable, and adaptable to new developments. The SOA approach also gives you the potential to lower costs (from reuse), and increase revenue (from adaptability and flexibility). However, integrating basic SOA constructs (such as Process, Business Services, and Components) and core building blocks of BPM (such as Process Modeling and Enterprise Service Bus) in a real-world application can be challenging.This book introduces basic concepts of Business Integration, SOA Fundamentals, and SOA Programming Model and implements them in numerous examples. It guides you to building an Order Management application from scratch using the principles of Business Process Management and Service Oriented Architecture and using WebSphere Process Server (WPS) and WebSphere Enterprise Service Bus (WESB). The various detailed aspects, features, and capabilities of the product are conveyed through examplesWe begin with essential concepts on Business Integration, SOA Fundamentals and SOA Programming Model. Then we set up the development environment to build your first Hello Process and Hello Mediation applications.Gradually, we build an SOA-based Order Management Application. We cover important aspects and functions of WPS and WESB with numerous practical examples. We show how to analyze your application''s business requirements and check if an SOA approach is appropriate for your project. Then you do a top-down decomposition of your application and identify its use cases, business processes, and services. Having built the SOA Application, we introduce you to various non-functional topics, including: Administration, Governance, Management, Monitoring, and Security. We also discuss deployment topologies for WPS and WESB, performance tuning, and recommended practices. What you will learn IBM s BPM platform and key products that make it up Understand fundamentals behind Service Component Architecture, Service Data Objects, WS-BPEL, and how they relate to BPM and SOA Business Process Choreography and mediation flow fundamentals including business rules, state machine, human tasks, and CEI Deliver a BPM enabled by SOA solutions using WPS WESB,Äôs smart approach to SOA by enabling integration, connectivity, and messaging capabilities Install and fundamentals behind working with WID including integration solution, assembly diagram, working with modules and libraries, unit test environment Build and deploy your first module project in WID and test business process applications Understand basic concepts of mediation flows including message filter, XSLT transformation, and service invoke primitive while building a mediation module Architect, design, and implement an "Order Management,Äùsolution using WID, WPS, and WESB Identify components necessary for the order management solution and map them to the IBM SOA reference architecture Identify SOA business services, create shared libraries, and leverage existing application interfaces Build the business process flows, business services and access services, integrate with back end applications and perform end-to-end integration tests Integrate this business process with existing applications using various capabilities provided by WID including JDBC and File adapters, JMS imports, and Web Service imports Explore topologies and deploy gold topology Fundamentals behind using and customizing Business Space Manage, monitor, secure, and administer your modules with the tools provided by WPS, WESB, and Business Space Numerous references, tips, and pointers for advanced and related topics Who this book is for

This book is for SOA architects, designers, and developers who have a basic understanding of SOA concepts and would like to learn more about building solutions and applications using IBM WebSphere Process Server and WebSphere Enterprise Service Bus.
