This paper presents the development of a software tool that enables thetranslation of first-order predicate logic into relation algebra. The tool wasdeveloped using the Z3 theorem prover, by leveraging its capabilities toenhance reliability, generate code, and expedite the development process. Theresulting standalone Python program allows users to translate first-order logicexpressions into relation algebra, eliminating the need to work with relationalgebra explicitly. This paper outlines the theoretical background offirst-order logic, relation algebra, and the translation process. It alsodescribes the implementation details, including validation of the tool using Z3for testing correctness, and discusses deviations from the original translationprocedure. By demonstrating the feasibility of utilizing first-order logic asan alternative language for expressing relation algebra, this tool paves theway for integrating first-order logic into tools that traditionally rely onrelation algebra as their input language.
