Understanding data mapping

Defining data mapping

Data mapping is the process of linking data elements from one dataset to corresponding elements in another dataset, often with the goal of data integration or data transformation. 

In the context of privacy and data protection, data mapping offers an essential tool for understanding what data a company collects, how it's used, and where it resides. Through this process, organizations can identify and document the flow of personal and sensitive data across various systems, databases, and silos. 

By giving business visibility into their data ecosystem, data mapping software enables simpler compliance with privacy regulations, like the GDPR and CPRA—both of which require an accurate understanding of data flows, processing activities, and storage locations.
