The KieBase is all about definitions (it contains all your processes, rules, etc.) and the KieSession is the runtime interface (how to start processes, do task mgmt, insert data, etc.). The KieContainer is just an interface you could use to create a KieSession etc. (based on a KieBase, identified by a unique release id).
Thank you. I get it.
But i don't understand because you can configure the KieBase and KieSession in the GUI. I thought he was more focused on work with the API.
Sorry if not much understand, I'm Spanish ... XD
