AIA defines a common vocabulary of common business entities and their corresponding services.
AIA defines a common vocabulary across applications and industries. Enterprise Business Objects (EBOs) are the key elements in this context. They canonically describe standard business entities such as an order or an invoice. Based on these generic business entities, AIA delivers other artifacts such as Enterprise Business Services (EBSs), Enterprise Business Messages (EBMs), Enterprise Business Flows (EBFs), Composite Business Processes (CBPs), and Application Business Connector Services (ABCSs). We will describe the purposes of these artifacts and their relationships to each other later when we explain the AIA reference architecture. The combination of all of these SOA artifacts makes up the adaptable and extensible service-oriented reference architecture that AIA stands for.
