RELAX — the relational algebra pocket calculator project

ACM SIGCSE Bulletin, 2000
Database courses benefit from the abundance of commercial SQL systems available today. Unfortunately, the same cannot be said about the relational algebra query language. This article considers a lab experience to integrate the learning of these two important topics.

Projective algebra and the calculus of relations

Journal of Symbolic Logic, 1978
In [1] there were given postulates for an abstract “projective algebra” which, in the words of the authors, represented a “modest beginning for a study of logic with quantifiers from a boolean point of view”. In [5], D. Monk observed that the study initiated in [1] was an initial step in the development of algebraic versions of logic from which have ...

Projectively stable artin algebras: representation theory and quivers with relations

Communications in Algebra, 1999
A left artinian ring Λ is projectively stable if no non-zero morphism f: M → N of finitely generated left Λ-modules M,N having no non-zero projective direct summands factors through a projective mo...
