  • SQL to tuple relational calculus conversion
  • SQL to domain relational calculus conversion
  • Step-by-step derivations
  • Interactive operator and quantifier scope trees
  • Comparison view of all notations
Features
Read full description

A native iPad and iPhone app that converts a SQL query typed, pasted, or imported from a .sql file into relational algebra, tuple relational calculus and domain relational calculus. Each notation gets a step by step derivation, a final oneline formula, and an interactive diagram an operator tree for the algebra, a quantifier scope tree for the calculus and a fourth view stacks all three against the same query. Whatever SQL asks for that a notation cannot express exactly is reported rather than quietly approximated.
