Article 37 GDPR states: “The appointment of the Data Protection Officer is based on professional competence, in particular a thorough knowledge of data protection law and practice, and the ability to carry out the task.” Many experts agree that the DPO should be a licensed attorney, not only sufficient knowledge of GDPR, but also of other privacy laws that are important to employers.

Marketing business analysts develop marketing plans for companies by collecting data and analysing market trends. Successful businesses rely on marketing analysts, sometimes called market research analysts, who use business intelligence to track trends, spot opportunities, and determine what products people want, who will buy them, and at what price.

A Data Protection Officer (DPO) is an employee or contractor hired to oversee a company's data protection strategy and ensure compliance with the General Data Protection Regulation (GDPR). The Data Protection Officer is responsible for ensuring that the organisation complies with the GDPR by acting as the data protection expert within the organisation and acting as a liaison between employees and members of the public who can find their information used and developed by the organisation.
