This paper describes two techniques for
Datalog
query evaluation and their application to object-oriented program analysis. The first technique transforms
Datalog
programs into an implicit Boolean Equation System (
Bes
) that can then be solved by using linear-time complexity algorithms that are available in existing, general purpose verification toolboxes such as
Cadp
. In order to improve scalability and to enable analyses involving advanced meta-programming features, we develop a second methodology that transforms
Datalog
programs into rewriting logic (
Rwl
) theories. This method takes advantage of the preeminent features and facilities that are available within the high-performance system
Maude
, which provides a very efficient implementation of
Rwl
. We provide evidence of the practicality of both approaches by reporting on some experiments with a number of real-world
Datalog
-based analyses.
