Solving equations in the relational algebra [PDF]
Enumerating all solutions of a relational algebra equation is a natural and powerful operation which, when added as a query language primitive to the nested relational algebra, yields a query language for nested relational databases, equivalent to the ...

Constraint Databases, Queries, and Query Languages [PDF]
We formally define the constraint database model, the concept of query in this model, and the basic constraint query languages provided by the relational calculus, the relational algebra, and DATALOG. We show how a computationally complete constraint query language can be obtained by augmenting the constraint relational calculus with basic programming ...

ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Data Model and Query Constructs for Versatile Web Query Languages [PDF]
As the Semantic Web is gaining momentum, the need for truly versatile query languages becomes increasingly apparent. A Web query language is called versatile if it can access in the same query program data in different formats (e.g. XML and RDF). Most
