Codd, Edgar F.

Edgar F. Codd was a computer scientist renowned for inventing the relational database model in the 1970s. His work transformed how data is stored, accessed, and managed by organizing information into tables with rows and columns, making it easier to retrieve and manipulate data efficiently. This approach replaced complex, hierarchical methods and laid the foundation for modern databases used in everything from banking to online services. Codd's principles continue to underpin most database systems today, revolutionizing data management with a logical, flexible, and scalable structure.
