jBPM® is a flexible Business Process Management (BPM) Suite. It makes the bridge between business analysts and developers. A business process allows you to model your business goals by describing the steps that need to be executed to achieve that goal and the order, using a flow chart. This greatly improves the visibility and agility of your business logic, results in higher-level and domain-specific representations that can be understood by business users and is easier to monitor.
The core of jBPM is a light-weight, extensible workflow engine written in pure Java that allows you to execute business processes using the latest BPMN 2.0 specification. Complex business logic can be modeled as a combination of business processes with business rules and complex event processing. In OS.bee, jBPM is used combined with the Drools project to support one unified environment that integrates these paradigms where you model your business logic as a combination of processes, rules and events.
Drools® is a business rule management system (BRMS) with a forward-chaining, inference-based (production) rules engine using an enhanced implementation of the Rete algorithm. The Business Logic Implementation Platform (BLIP) by Drools encodes the real-world business rules that determine how data can be created, displayed, stored, and changed. It describes rules and workflows that focus on improving corporate performance by managing and optimizing a company’s business processes.
