Composite key matching

As explained in First-Party Data Activation

Composite key matching is a record-linkage method that matches records when multiple corresponding field values jointly agree.

Composite key matching links records when multiple corresponding field values agree, using a deterministic, rules-based approach to identity resolution. It is recommended as one possible foundation for unifying customer data. section 6.1.1 section 6.4

How First-Party Data Activation covers it

How deep it goes

Defines composite key matching as a rules-based strategy but provides no detailed account of matching mechanics.

Examples

Uses a diagram of composite field identity resolution as its visual example.

What you can do after

Evaluate composite key matching as one foundational deterministic option for identity resolution.

How it connects

Connects composite key matching to identity resolution, first-party data strategy, single-field matching, and deterministic cascade matching.
