Data Mapping
Data Management
Documentation of data flows, sources, destinations, and transformations across systems and vendors.
Definition
Data mapping identifies data sources, processing steps, storage locations, recipients, and transformations (ETL). It supports compliance, security architecture, and incident response.
Why this matters
Why it matters: Understanding flows is critical to minimize sharing, apply encryption, and honor deletion/access requests.
Example
Example: Map personal data fields to each system and vendor, then reduce or encrypt high-risk flows and set retention rules.
