Employee onboarding data flow.
This GDPR data flow diagram maps the main systems involved in onboarding a new employee. Personal and tax details enter through an HR portal, then an onboarding service creates the employee record, logs the event and sends limited information to payroll and identity providers. Separating the external providers from HR systems makes the data disclosures visible for a vendor review. The flow can help an HR and privacy team ask where each category of data is stored, who receives it and which systems need access. Add local systems, actual data categories and retention rules before using the drawing in formal documentation. It supports privacy analysis but does not replace employment-law or data-protection advice.
