Who is known for the relational model in database design?

• A. Dr. Alan Turing
• B. Dr. Edward Codd
• C. Dr. John von Neumann
• D. Dr. Grace Hopper

Answer: (B)

Dr. Edward Codd is widely recognized for introducing the relational model for database design. He formulated this model in the 1970s, which fundamentally changed how data is structured, stored, and queried. Codd's relational model emphasizes the concept of organizing data into tables (also known as relations) where each table consists of rows and columns. This model allows for the application of mathematical set theory and predicate logic to manage data, enabling powerful querying capabilities through structured query languages, such as SQL. Codd's principles laid the groundwork for various relational database management systems that are heavily used in industry today. His work established standards for how data relationships and integrity should be maintained, revolutionizing the approach to databases and paving the way for more advanced data management practices and technologies. Other options represent notable figures in computing but are not directly associated with the development of the relational database model.
