We describe the MyYapDB, a deductive database system coupling the Yap Prolog compiler and the MySQL DBMS. We use our OPTYap
extension of the Yap compiler, which is the first available system that can exploit parallelism from tabled logic programs.
We describe the major features of the system, give a simplified description of the implementation and present a performance
comparison of using static facts or accessing the facts as MySQL tuples for a simple example.
