Transaction

Go up to Terms and Definitions

A Transaction represents a recordable business event or proposed business event involving one or more parties, obligations, rights, values, assets, instruments, services, or settlement expectations.

In a financial system, a Transaction provides the business context for validation, interpretation, state management, settlement, audit, provenance, evidence, and review. A Transaction may describe an agreed financial event, a proposed financial event, an instruction, an order, a transfer, a contract event, or another governed business interaction, depending on the applicable domain profile.

The Financial Systems Archetype treats a Transaction as a conceptual business item, not as a message, file, database record, API payload, or runtime event. Later, logical and implementation profiles define the information structures, endpoints, services, and artefacts that represent or process transactions.
