Integrating LGPD Requirements and Restrictions into Database Design

The Brazilian General Data Protection Law (LGPD) specifies how the processing, storage, and disposal of personal data should be conducted, conditioning it to the prior authorization of the data subject. On the other hand, current information systems are heavily reliant on the use of personal data and therefore need to comply with the LGPD. However, the methodologies and tools used for database design do not incorporate the requirements and constraints of the LGPD, making it difficult to ensure compliance between databases and current legislation. This article presents a methodology, called LGPDbyD, to incorporate the impositions and principles of the LGPD into the design of databases. To achieve this, we adapted the ER model, the Relational model, and the CREATE TABLE command.
