创立 rule service interface 的目标:应用程序通过将规定与规定服务的规定集相关联来调用决策逻辑。
A rule service is an interface or an end point that enables an application to invoke a decision logic.
rule service 能够看成一个接口或者 endpoint,应用程序通过调用 rule service,能够触发 decision logic.
Rule set 是一系列 rule 的汇合,工作于某个特定的场景。
A rule set can be linked to a rule service so that the set of rules in the rule set gets executed when the rule service is deployed.
规定集能够链接到规定服务,以便在部署规定服务时执行规定集内蕴含的所有规定。
