Customer Data Platform

Also: CDP

A system that unifies a company's first-party customer data from every source into persistent profiles keyed to known individuals, then makes those profiles available to marketing, advertising, and analytics tools. CDPs (Segment, mParticle, Salesforce Data Cloud, Adobe Real-Time CDP, and composable approaches on the data warehouse) are the practical home of First-Party Data strategy.
