This document provides definitions and explanations of a data management platform (DMP). It summarizes that a DMP is a centralized system that collects proprietary and third-party data, integrates that data, and applies it to advertising strategies. It allows users to create custom segments, predict volumes, and synchronize segments across sources for advanced analytics and integration with demand-side platforms. The core elements of a DMP include data integration, management capabilities for segmentation, data labeling for flexibility, a self-service interface, and connections to relevant marketing channels. A DMP's main functions are to record, save, analyze, and identify targets from collected data to provide customized ad delivery and enhance customer relationship management through more accurate advertising.
