Towards Practical Constraint Databases (Extended Abstract)

Summary: Framework for real constraint databases using finite-precision arithmetic, formalizing finite-precision query semantics to handle approximate values typical in scientific applications. Proves aggregates and analytical functions can be added while preserving closed-form PTIME data complexity and introduces CALCF, a practical constraint query language with these guarantees.
