Title: Relational Algebra Revisited: Toward an Object-Predicate Oriented Relational Model
Authors: Victor Markowitz
Abstract: The domain-oriented approach to the Relational Model brought its data description side closer to the way people perceive information, that is, following an object-predicate pattern. Accordingly, one would expect that the model's manipulative part would reflect the way people communicate, namely by natural language.

To this end we propose to modify the Relational Algebra in order to mate each of its operations to have a linguistic analog. Moreover, the construction of complx algebraic expressions will follow patterns of natural language sentence combination. The change presrves the expressive power of the original Relational Algebra and makes the relational manipulation easier due to its new, natural language orientation.
