Path Expressions in Databases (Extended Abstract)
Summary: Introduces path-expression framework to analyze consistency of database states with sets of functional dependencies via weak instances and CONS(R,F) (states of R consistent with F). Gives an iff characterization for CONS(R,F)⊆CONS(R,G) and a polynomial-time tableau/chase-style algorithm using merging arguments to decide these dependency comparisons.
