Principle 4 -Accuracy

Article 5 of the GPDR states that personal data must be "accurate and, where necessary, kept up to date". No incorrect or misleading information should be stored. Therefore, all reasonable steps must be taken to ensure that the personal data processed is accurate and regularly updated

Individuals do indeed have the right to request the deletion or rectification of inaccurate data. However, outdated data does not always mean inaccurate data, e.g. in the case of historical records. Consequently, it must always be clear what the intention behind the processing and storage of personal data is, because what it is used for may have an impact on whether it is accurate or not

To better illustrate this last idea, here is an example:
If a person moves from Madrid to Barcelona, a record that says they currently live in Madrid is obviously "innacurate". However, a record that says the person once lived in Madrid remains "accurate" even if they no longer live there.

Another example:

A hospital updates its database. What happens to the data of patients who have been misdiagnosed? Well, even if the diagnosis is corrected, the information is part of the patient's medical record. In this case, the information is relevant to explain a specific treatment given to the patient or other health problems that occurred as a result of the treatment
