This week's paper is "A Relational Model of Data for Large Shared Data Banks" by E.F. Codd, published in 1970.

Codd's paper introduces a revolutionary approach to database design that fundamentally changed how we store and access data. Rather than navigating through complex hierarchical or network structures, he proposed organizing data into simple tables (relations) with rows and columns that could be manipulated through a set of well-defined operations.

This groundbreaking model provided true data independence - protecting users from changes in how data is physically stored and represented. Its elegant mathematical foundation enabled a level of flexibility and expressiveness previously impossible, ultimately leading to SQL and the relational database systems that power nearly every application we use today.
