Definitions

In plain terms

It is the lookup layer that answers which instrument a market record refers to, even when names or tickers have changed.

Technical

A reliable security master maintains source provenance, bitemporal or effective-dated history, typed identifier crosswalks, relationship cardinality, and non-destructive revisions.

Scope

A security master is a system and data contract, not a single universal vendor file.

Examples

  • A governed dataset records security master explicitly instead of inferring it from an ambiguous field.

Common misconceptions

  • Security Master does not have one universal meaning without its stated market, source, and time context.
