说明：  近年来，企业中商业规则频繁变动已成为一种趋势，并且这种规则变动的原因多半来自于非开发人员，或者说是业务人员。面对复杂的企业级项目开发及其随着外界环境条件的变化而变化的业务规则，譬如银行、保险领域，业务规则是非常复杂的，并且规则处于不断更新变化中。而现在很多系统的做法基本上都是将业务规则绑定在程序代码中，这就给系统的维护、更新带来极大的困难，更不可能让非开发人员来管理。 因此，迫切需要一款产品，它能将业务决策逻辑从系统逻辑中抽离出来，使两种逻辑可以独立于彼此而变化，使非技术业务人员能直接参与到业务规则管理工作中，使受限于复杂多变且不断发展的业务规则的应用程序和流程实现灵活的决策自动化。决策引擎作为常见的维护策略规则的框架是一个理想的选择
(In recent years, frequent changes of business rules in enterprises have become a trend, and the reasons for such changes are mostly from non developers, or business personnel. In the face of complex enterprise level project development and business rules that change with the changes of external environment, such as banking and insurance, business rules are very complex, and the rules are constantly updated and changing. Now many systems are basically binding business rules in the program code, which brings great difficulties to the maintenance and update of the system, and it is impossible for non developers to manage it.)
