Towards unified knowledge management platform (rulefest 2010)
2 likes1,051 views
The document discusses the need for a unified business knowledge management platform. It argues that traditional BRMS and CEP solutions are no longer sufficient, as business knowledge includes not just rules but also processes, models, and event processing modules. An effective platform should provide a unified view and lifecycle management of all knowledge assets. It presents Drools as a platform that can fulfill this role by integrating rules, processes, and complex event processing capabilities.
