Preface

Oracle Application Integration Architecture (AIA) Foundation Pack is a commercial integration framework provided by Oracle Corporation. Oracle AIA provides a systematic approach of building business process integrations for an enterprise that helps it to consolidate their IT assets. Oracle AIA foundation pack also provides a set of application independent Enterprise Business Objects, Enterprise Business Messages, Enterprise Business Services, SOA based reference architecture, and test methodologies that help to build uniform integration infrastructure. Using AIA Foundation Pack, an enterprise can achieve quicker SOA adoptability and reusability. Oracle AIA framework requires Oracle SOA Suites in both design time and runtime environments.

The scope of this book is to provide the readers with essential details about various AIA foundation pack components and the role of each component in integration architecture. The book starts with generic integration architecture, approaches, and importance of building application integrations using the SOA approach.

What this book covers

Chapter 1, Overview of Oracle AIA revisits the fundamentals of integrations, advancement of integration using Service Oriented Architecture, and the role of Oracle AIA Foundation Pack in the application integration scenarios. At the end of this chapter, the reader will get a good understanding of various integration types and an overview of Oracle AIA FP and its architecture model.

Chapter 2, Enterprise Business Objects explains the concept of business objects, need of business objects, Enterprise Business Objects (EBOs), various types of EBOs, and physical locations of the EBO files in the Oracle AIA Foundation Pack. This chapter also covers the need of customizing the EBO components.

Chapter 3, Enterprise Business Messages covers integration messaging model, business messages, web service messaging, and Enterprise Business Messages. Also, it explains the relationship of an EBO and EBM in the AIA approach. This chapter also covers the physical location of EBM in the AIA FP installation and the need for customizing EBM.

Chapter 4, Enterprise Business Services covers the need of business services, web service operations, and role of Enterprise Business Services in the AIA model. Also, this chapter will help to find the appropriate WSDL file in the AIA FP path and screen-by-screen instructions to build the EBS using JDeveloper.

Chapter 5, Applications Business Connector Services covers the role of ABCS in the AIA approach, the need of ABCS, and screen-by-screen approach to build ABCS using JDeveloper. At the end of this chapter, the reader will have hands-on experience in building the ABCS component.

Chapter 6, Enterprise Business Flow covers the need of business processes in application integration and building business processes using Oracle BPEL. This chapter also covers the systematic instructions to build the business processes by making use of AIA components.

Chapter 7, AIA Security covers the various levels of security requirements for application integrations and how Oracle AIA supports security through Oracle SOA Suite. This chapter also explains the steps required to build AIA security by defining security policies and securing ABCS.

Chapter 8, AIA Versioning covers the importance of version management in integration and versioning approach followed in AIA. This chapter also covers versioning techniques for various AIA components including EBO, EBM, EBS, and ABCS.

Chapter 9, AIA Design Patterns covers the various message exchange patterns with diagrammatic explanations. This chapter also covers the AIA supported message exchange patterns, asset management patterns, and so on. At the end of this chapter, the reader will have a detailed understanding of various AIA integration design patterns and samples.

Chapter 10, Error Handling and Logging covers the various type of faults including business faults and system faults. Also, it covers the AIA error handling framework, configuring fault handlers, error notification approach, and various logging mechanisms supported by AIA configurations.

Chapter 11, Service Management using Oracle Enterprise Repository covers the SOA governance models, introduction to Oracle Enterprise Repository, and service management using OER. This chapter also guides the reader to import the AIA configurations in the OER and harvesting design time configuration.

Chapter 12, Composite Application Validation System explains the Oracle AIA CAVS framework, CAVS role in the AIA approach, test definition, simulator definitions, and CAVS user interface. As this chapter guides the reader to create and test definitions and simulators using CAVS, the reader would get a basic understanding of applying CAVS in the AIA project.

Appendix, covers a case study with real time scenarios, which explains how AIA components are used to accomplish the integration requirement. The case study explains the approach followed to identify the EBO, EBM, EBS, and ABCS components required to build the integration for the real time use case. At the end of this chapter, the reader should have a good understanding of how to approach AIA integration project from design to implementation
