A Look Inside JBoss Rules

JBoss Rules is the production release of the Drools project, an expert system for declarative programming based around the Rete algorithm. During this talk, recorded by Skills Matter, Mark Proctor, the lead on JBoss Rules covered the Drools basics, as well as the new features in 4.0 and how they aid declarative programming. Drools 4.0 extends traditional Rete systems with support for powerful Conditional Elements such as 'accumulate', 'collect' and 'from' as well as Rule Flow for execution flow control. Drools 4.0 also introduces the new web based Business Rules Management System.
