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. 

The need for data mapping tools

Data mapping software is a critical piece of privacy compliance. As regulators around the world tighten data privacy laws, organizations must be able to demonstrate where and how they collect and use personal and sensitive data. 

Without a robust data mapping tool, privacy teams are forced to manually create and maintain an accurate, up-to-date record of data flows across complex, interconnected systems—a process that can be exceedingly difficult and error prone. 

Modern tools automate the process, providing an accurate, real-time picture of where personal data resides, how it moves through company systems, and who has access to it. This not only supports compliance with regulations like GDPR and CCPA, but also helps businesses respond to data subject requests. 

Data mapping process

Manual data mapping

With an automated data mapping tool, organizations have to use manual data mapping processes. The general steps are:

1. Identify all sources of data within the organization, which can include everything from customer data warehouses and databases to employee records.
2. Evaluate the nature of the data that each data source holds. This involves categorizing data into types such as personal data, sensitive data, and non-personal data—a crucial piece of privacy law compliance.
3. Conduct a privacy impact assessment. This involves identifying potential risks in the data flow and assessing the both likelihood and impact of each risk. This step also helps to identify any areas of non-compliance.
4. Develop and implement strategies to mitigate identified risks. This might involve changing data handling processes, improving data security measures, or training staff on data privacy practices.

Manual data mapping processes can be time-consuming and complex, particularly for large organizations with lots of data. However, it provides crucial insights into the organization's data landscape and can play a vital role in ensuring data privacy compliance.
