Abstract

A new operator, the entity join, is proposed as an extension to the relational model. While similar to the traditional join, it is based on common entities rather than matching representations. The entity join avoids a number of problems arising from the loose correspondence between names and entities, it rationalizes the traditional join, and it extends the usability of the relational model.
