SAP Integration Repository is the design configuration piece of the SAP Exchange Infrastructure (XI), the process integration layer of the NetWeaver component from SAP, the company that sells a widely-used enterprise application platform. The SAP Exchange Infrastructure uses Web standard interfaces such as Web Services Definition Language (WSDL), XML Schema Definition (XSD), and Simple Object Access Protocol (SOAP) so that SAP applications can communicate with non-SAP applications. At design time, the user defines or uses pre-defined interface objects for the SAP Integration Repository. These objects include Business Scenarios, Business Processes, Message Interfaces, Message Types, Data Types, Message Mappings, and Interface Mappings. The application developer refers to these objects in defining the interactive flow between applications for the SAP Integration Directory. When an application is executed, the messaging flow is drawn from the Integration Directory. During execution, depending on specified code, the SAP Integration Server may send messages to multiple receivers; split a message into multiple messages; route a message based on content; and so forth.
