The present disclosure includes systems and techniques relating to integration of a service-oriented transaction system with an information storage, access and analysis system, such as a Business Intelligence (BI) infrastructure. In general, in some implementations, a data transformation interface and a data transfer interface can be configured to effect data exchange between a computer-based information storage, access and analysis system including a second data model, and a computer-based service-oriented transactional system including a first data model. The data transformation interface and the data transfer interface can be configured to communicate through a decoupled information exchange that separates program implementation details of the data transfer interface from the data transformation interface. Furthermore, in some implementations, an agent framework can be used to decouple data transformation from data transfer, where the agent framework includes a generic agent and application specific agents.
