Drools is a Business Rules Management System (BRMS) solution. It provides an Eclipse IDE plugin for core development. Using these frameworks, users define rules which specify what action needs to be done when a particular condition is met. In projects, it's usually used to determine Business Rules which are composed of facts and conditional statements. It also provides a web authoring and rules management application (Drools Workbench) and full runtime support for Decision Model and Notation (DMN) models.
