[rules-users] Maintaining DB/Working Memory Synchronization

So I hope that someone out here, or many of you, can give me some idea of how you do this. I have about 20+ entities in my database that I want Drools to know about. Obviously my hope is to apply CEP, rules and processes to these items. However, I feel like I'm missing some type of connection between how Drools recommends keeping my working memory in sync with my database changes. Ideally, I'd love to be able to just update my entities as I have been doing in the database, but have those changes automatically move their way over into the working memory. How do any of you recommend I accomplish this? Thanks in advance for any suggestions. Dan Miller
