Personal Data are a part of every person's life. Personal Data Protection is a quite broad issue, we don't usually notice it until our Personal Data has been misused and our privacy has been infringed. That's why it's important to know who, when, where has access to what extent of our personal data, and how they process them. Moreover, violation of Personal Data Protection entails a risk of stiff fines. Knowledge of regulations considering Personal Data is important not only for persons processing the data, but also for natural persons, whose data are being processed (data subject).
