"Edgar F. Codd, a mathematician and computer scientist who laid the theoretical foundation for relational databases, the standard method by which information is organized in and retrieved from computers, died on Friday at his home in Williams Island, Fla. He was 79."
"The cause was heart failure, said his wife, Sharon B. Codd."
"Computers can store vast amounts of data. But before Dr. Codd's work found its way into commercial products, electronic databases were "completely ad hoc and higgledy-piggledy," said Chris Date, a database expert and former business partner of Dr. Codd's, who was known as Ted."
