|Abstract: ||In the database programming language PASCAL/R, the programming language
PASCAL and concepts based on the relational data model are integrated.
The paper investigates transformation strategies used in the PASCAL/R
system to evaluate queries with existential and universal quantifiers.
Intermediate data structures are described using a high-level language
tool called a reference to a selected variable. The predicate calculus
approach used in PASCAL/R offers new insight into recently proposed
query optimization techniques and allows some of them to be extended.|
