Drools is a business rule management system with a forward-chaining and backward-chaining inference based rules engine, allowing fast and reliable evaluation of business rules and complex event processing. A rule engine is also a fundamental building block to create an expert system which, in artificial intelligence, is a computer system that emulates the decision-making ability of a human expert.

Test execution tip
Some test are meant to be executed on machine with en_US locale.
A specific profile is provided to execute them on machines with different locale, namely test-en.
There are two ways to activate such profile during maven build:
-Ptest-en(profile-id based)-DTestEn(property based)
The following two commands will execute tests on machine with locale different than en_US:
make test -Ptest-enmake test -DTestEn
