What is the Rules Engine

While building any application, the crux or the core part of it is always business logic or business rules. And as with any application, there always come a time when some or a lot of the rules or policies change in the system. But with that change, comes a lot of rework like changing design or creating a new module altogether to code in the changes in the rules, regression testing, performance testing etc. The rework along with debugging if required amounts to a lot of unnecessary work which can otherwise be utilized for other work, thus reducing the engineering cycle by drastic amounts.

In this library, we have abstracted the rules so that the core logic is always maintained while the rules change can happen in an easy way without changing the code base. Also, the input to the system is dynamic in nature so the model need not be defined in the system. It can be sent as an expando object or any other typed object and the system will be able to handle it.

These all features make this library highly configurable and extensible as shown in Getting Started with Rules Engine.
