For security reasons, I prefer MongoDB Atlas. It supports role-based access control, so you have an entity for each individual.
MongoDB Atlas is praised for its seamless integrations and easy initial setup processes. Its schemaless architecture and cloud-based nature grant flexibility and scalability, enhancing performance stability. Automated backup and restore functionalities are beneficial for secure data management. Despite offering features like automatic sharding and clustering, installation can be complicated. It is not ACID compliant, and technical support and pricing need improvement. The data aggregation feature should also work faster.
