What is Data Enrichment

Definition

Data enrichment is the process of enhancing existing records by adding relevant information from internal or external sources, such as appending demographic, geographic, or firmographic attributes, so the data becomes more complete and valuable for analysis and personalisation.

Improves segmentation and targeting by appending attributes the source never captured
Increases the value of existing data without re-collecting it from customers
Supports better models by giving them additional, externally sourced features

Real World Example
