What is Drools ? How Drools,Guvnor,Expert ,jBPM,Drools Fusion and optaPlanner all relate to?
I am completely new to Drools although I have written very small rules and deployed in Guvnor.
All that I have done is write series of if and else statements and deployed in the Guvnor.
I am wondering what is the use of this product?
Why there are different products in the same banner and what is the relation ship to each of them?
Importantly how Drools,Guvnor,Expert ,jBPM,Drools Fusion and optaPlanner all relate to ?
Why do we need a lot of them ?
Solution
Maybe this overview from the documentation helps:
You don't have to use all of them. Just use what you need and expand if your requirements grow.
