Full Description
This book is a comprehensive guide, split into three sections. The initial section of the book provides an introduction to the Oracle SOA Suite and its various components, and will give you a fast-paced hands-on introduction to each of the key components in turn. The next section illustrates the usage of the various components of the SOA Suite to implement a real-world SOA-based solution with the help of an example of an online auction site (oBay). The final section covers other considerations such as the packaging, deployment, testing, security, and administration of SOA applications. This book targets developers and technical architects who work in the SOA domain. The primary purpose of the book is to provide them with a "hands on" practical guide to using and applying the Oracle SOA Suite in the delivery of real-world composite applications. It presumes basic understanding of the concepts of SOA, as well as some of the key standards in this space, including web services (SOAP, WSDL), XML Schemas, and XSLT (and XPath).
Contents
Section 1 Getting Started Chapter 1Suite: An initial introduction to the Oracle SOA Suite and its various components. Chapter 2: Writing your first service: A hands-on introduction to the core components of the Oracle SOA Suite, namely the Oracle BPEL Process Manager and the Oracle Service Bus. Chapter 3: Service-enabling existing systems: Looks at a number of key technology adapters and how we can use them to service-enable existing systems. Chapter 4: Loosely coupling services: Describes how we can use the Oracle Service Bus to build services that are implementation-agnostic. Chapter 5: Building composite services and business processes: Covers how to use BPEL to assemble services to build composite services and long-running business process. Chapter 6: Adding in human workflow: This chapter looks at how human tasks can be managed through workflow activities embedded within a BPEL process. Chapter 7: Using business rules to define decision points: This chapter introduces business rules and how we can use them to externalize "decision points" in a BPEL process. Chapter 8: Building real-time dashboards: This chapter looks at how Business Activity Monitoring (BAM) can be used to give business users a real-time view into how business processes are performing. Section 2 Putting it all together Chapter 9: oBay introduction: Provides a blueprint for our SOA architecture, highlighting some of the key design considerations and describing how they fit our architecture for oBay. Chapter 10: Designing the service contract: Gives guidance on how to design XML schemas and service contracts for improved agility, reuse, and interoperability. Chapter 11: Building business services: Examines different approaches for building new business services either from scratch or by re-using existing logic. Chapter 12: Building validation into services: Examines how we can implement validation within a service using XSD validation, Schematron, and Business Rules. Chapter 13: Error handling: This chapter examines strategies for handling system and business errors, with detailed coverage of the BPEL Fault Management Framework. Chapter 14: Message interaction patterns: Covers complex messaging interactions, including multiple requests and responses, timeouts, and message correlation (both system and business). Chapter 15: Workflow patterns: Looks at how to implement workflows involving complex chains of approval and how to use the Workflow Service API. Chapter 16: Using business rules to implement services: Here we look at the Rules engine s inferencing capabilities, and how we can use them to implement types of business services. Chapter 17: The importance of bindings: Looks at the protocols available in addition to SOAP over HTTP for invoking web services and the advantages they provide. Section 3 Other considerations Chapter 18: Packaging and deployment: Examines how to package up a SOA application for deployment into environments such as test and production. Chapter 19: Testing composite applications: Looks at how to create, deploy, and run test cases that automate the testing of composite applications. Chapter 20: Defining security and management policies: Details how to use Web Service Manager to secure and administer SOA applications.
