This chapter includes the following sections:
The Oracle Application Integration Architecture (AIA) Foundation Pack: Development Guide defines in detail how you can use the Oracle AIA Foundation Pack to conceptualize AIA projects and, using the AIA Project Lifecycle Management application, implement a solution conforming to the AIA in a structured fashion based on a functional design document. You can use this guide to implement additional functionalities in the form of new services extending the AIA Process Integration Packs (PIP) functionalities.
Following this guide is the key to ensuring that the AIA solution that you build and implement can be upgraded, supported, and maintained.
AIA addresses two types of integrations:
Functional integration weaves together the various functionalities of different participating applications, exposed as services, as processes to accomplish business tasks that span multiple applications in any enterprise.
Data integration connects applications at the data level and makes the same data available to multiple applications. This type of integration relies on database technologies and is ideal when a minimum amount of business logic is reused and large amounts of data transactions are involved across applications. This type of integration is suitable for batch data uploads or bulk data sync requirements.
AIA provides reference architecture for a variety of situations. Depending on the size and complexity of integration projects, the integration style adopted for implementing integration flows varies. The number of participating applications and their role in integration flows contribute to the integration style adopted.
The integration flow as shown in Figure 1-1 represents the journey of a message from a business event triggering source to one or more target milestones, after passing through possible intermediary milestones. At each milestone, the message is stored in a different state.
The integration flow represents the run-time path of a message. It is not a design time artifact.
AIA addresses the following integration styles:
Integration Through Native Application Interfaces Using the Oracle Applications Technology Infrastructure
Integration styles with integration framework
Direct Integration Through Application Web Services Using Oracle SOA Suite
Integration Through Packaged Canonical and Standardized Interfaces Using Oracle Foundation Pack
Integration styles for bulk data processing
Real-time data integration flow
Batch data integration flow
The sales process provides detailed information about the value of AIA offerings. The value presented is perceived in the context of a business problem for which a solution is being sought.
A detailed description of the business case
Various use cases detailing the various usage scenarios including the exception cases with expected actions by various actors
Details about all the participating applications - commercial, off-the-shelf with versions and homegrown
Details about the triggering business events
Details about the functional flow
Details about business objects to be used
Actions to be performed on the various business objects
Details about performance and scalability requirements
The AIA Development Guide assumes:
A Functional Design Document is available
Access to AIA software
Access to all AIA-provided documents
You have read the AIA Concepts and Technologies Guide
The AIA Development Guide is logically divided as follows:
Overview of all tasks for building the AIA integration flow
Details of development of various AIA artifacts
Activities around interaction between AIA artifacts and external artifacts
Discussion of various design patterns, best practices, and tuning for run-time performance
Start with Chapter 20, "Building AIA Integration Flows" and move to relevant chapters in the Development Guide as needed.
