The relational model is a database model that represents data as two-dimensional tables made up of rows (tuples) and columns (attributes). Unlike hierarchical, network, or object models, it allows relationships between data to be expressed flexibly through table joins. It forms the theoretical foundation of relational database management systems (RDBMS), which are widely used today.
