The Knowledge Engineering Review, 1989
AbstractThis paper surveys a variety of deductive database theories. Such theories differ from one another in the set of axioms and metarules that they allow and use. The following theories are discussed: relational, Horn, and stratified in the text; protected, disjunctive, typed, extended Horn, and normal in the appendix.

ACM SIGACT News, 1989
Complex object databases have been proposed as a significant extension of relational databases, with many practical applications. In the second database theory column, we present languages for the manipulation of such databases: a many-sorted algebra and an equivalent calculus.

Assumptions in relational database theory
Proceedings of the 1st ACM SIGACT-SIGMOD symposium on Principles of database systems - PODS '82, 1982Many results in relational database theory on the structure of dependencies, query languages, and databases in general have now been established. However, neither (a) the reliance of these results on various assumptions, nor (b) the desirability or reasonableness of these assumptions themselves have been closely examined.
