Understanding  Data Matching

Data matching is the process of comparing data across different sources in order to identify similarities or matches. This can be done using various methods, such as identity resolution, cross-device matching, and data deduplication. It is an important technique used in many industries, especially in people-based marketing where matching customer identities across multiple devices is crucial.
