Business Transaction

A Business Transaction is a consistent change in the state of the business that is driven by a well-defined business function. [Papazoglou,2003]

A business transaction is driven by well-defined business tasks and events that directly or indirectly contribute to generating economic value, such as processing and paying an insurance claim, and has also an associated number of parameters that represent Security and timing requirements. Business transactions always either succeed or fail with respect to the business tasks (functions) that initiated them and govern them throughout their execution. If a business transaction completes successfully then each participant will have made consistent state changes, which, in aggregate, reflect the desired outcome of the multi-party business interaction.

At structural level, a business transaction is made up of a requesting (initiating) business activity performed by an initiating partner (party) and a responding business activity performed by the responding business partner. The initiating business activity sends a business document to a responding business activity that may return a business signal (signifying the completion of an activity) and possibly a business document as the last responding message. A transaction is associated with an SLA that describes the agreed upon Quality of Service (QoS) requirements and usually outlines what each party can do in the event the intended actions are not carried out (e.g., promised services not rendered, services rendered but payment not issued).

A series of collaborative activities that explicitly enforces the achievement of an agreed-upon business objective in end-to-end processes. This objective is subject to service-level agreements that govern the choreographed/orchestrated behavior, non-functional and timing requirements, correlated exchange of information, and control flow of composed services.
