GDPR data flow diagrams assist you in identifying all of the information you have and how it moves from one location to the other, such as suppliers and sub-suppliers to customers. Although the GDPR does not require data mapping, it is an excellent way to understand the personal data handled by the organization. GDPR data flow diagrams are typically created by a data architect collaborating with functional and technical application and process owners and facilitated through interviews and workshops. Processes generally are used to create data flow diagrams and graphical representations of the flow. They will aid in comprehending the information lifecycle and represent all in- and cross-application flows.
