Definitions
In plain terms
Two rows that look alike may be separate trades, while two different-looking messages may be corrections of one event.
Technical
Deduplication requires source-scoped identifiers, sequence and lifecycle semantics, field normalization, time bounds, and a deterministic survivor or merge policy.
Scope
Equal field values alone are not sufficient proof of duplication.
Examples
- A governed dataset records duplicate record explicitly and preserves the source context needed to interpret it.
Common misconceptions
- Duplicate Record does not have one universal meaning or policy without its declared source, scope, and data contract.
