UBIQUITOUS-LANGUAGE

Shared business vocabulary in bounded context.

Definition

The ubiquitous language removes implicit translation between business and tech. Class, method, and table names reflect exact business terms. Evolves with the domain. Documented in the code (and tests), not in separate docs. Crucial for Event Storming and CQRS-friendly designs.

Origin

Concept published by Eric Evans in Domain-Driven Design (2003), chapter 2.

Example in context

At Stellantis it is 'pre-shipment notification' (ASN) in Procurement and 'manifest' in Logistics — two bounded contexts.
