Gral: An Extensible Relational Database System for Geometric Applications
Summary: Extensible relational DB enabling user-defined data types, operators, and relation algebra. Queries and execution plans are expressed in many-sorted algebra, yielding a uniform architecture and simplified rule-based optimization; demonstrated via a geometric database extension.
