| An open source rule engine, [DMN engine](https://drools.org/learn/dmn.html) and complex event processing (CEP) engine for Java™ and the JVM Platform. |
| |
| 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: |
| 1. `-Ptest-en` (profile-id based) |
| 2. `-DTestEn` (property based) |
| |
| The following two commands will execute tests on machine with locale different than _en_US_: |
| |
| 1. `mvn clean verify -Ptest-en` |
| 2. `mvn clean verify -DTestEn` |
| |
