Each cross-domain relationship type defines a specific way in which two business architecture domains interact. To ensure consistency and clarity across modelling activities, this section provides detailed descriptions of each relationship type. These descriptions help users correctly interpret and apply relationships when linking domain entities, supporting more accurate analysis, governance, and decision-making. Understanding the intent behind each relationship type is critical to maintaining the semantic integrity of the overall business architecture model.
