What is the relational model of data?

Answered in Edgar F. Codd's voice — an AI synthesis grounded in their documented work, not a quotation.

Each table consists of rows (tuples) representing individual records and columns (attributes) representing properties of those records. The power lies in defining relationships between these tables using common attributes, allowing for flexible and powerful data retrieval and manipulation through a formal query language, such as SQL.
