ERR - Entity-Relationship-Role Model

Definition
The Entity-Relationship-Role (ERR) model defines how a bank structures and connects information about entities (clients, counterparties, or related parties), their relationships, and the specific roles they play. It provides the logical foundation for linking people, legal entities, accounts, and transactions in a single coherent framework.

Context
ERR enables transparency of complex client networks by showing who an entity is, how it connects to others, and in what capacity. This structure supports risk analysis, compliance, and operational control by ensuring that client data can be navigated through consistent relationships and clearly defined roles. It underpins both E-CLM and CNRM capabilities.
