An Evaluation of Historical Algebras,

Abstract

This paper surveys historical algebras, extensions of the conventional relational algebra that support representation of the temporal dimension of real-world phenomena in databases. The authors identify twenty-one criteria for evaluating historical algebras. These criteria are well-defined, have an objective basis for being evaluated, and are arguably beneficial. Incompatibilities among the criteria are also identified. Nine historical algebras are evaluated against the criteria.
