PostgreSQL (with JSONB support)

PostgreSQL is a powerful, open-source database system that stores and manages data efficiently. With JSONB support, it can handle complex, flexible data structures similar to JSON objects used in web development. JSONB allows PostgreSQL to store semi-structured data directly within the database, making it easier to work with dynamic or nested information without needing separate tables. This combination provides both reliable data integrity and the ability to efficiently query and manipulate complex, variable data formats, making PostgreSQL versatile for a range of applications from traditional records to modern, data-rich systems.
