Edgar F. Codd (computer scientist)

Edgar F. Codd was a British computer scientist best known for developing the relational database model in the 1970s. This model organizes data into tables that can be easily accessed and manipulated, fundamentally changing how databases are structured. Codd introduced key concepts like data independence and the use of a structured query language (SQL) for managing data. His work laid the foundation for modern database systems used in various applications, from business to online services, making data management more efficient and effective. Codd's ideas continue to influence technology and data science today.
