Here we are going to build a sample Drools project using maven dependencies, and this will not require any pre-setup of drools in your eclipse to build the project.
In the sample demo project, we will be creating a Maven Project in which with the help of drools we will decide what discount is to be offered on which Bank Card. For example, if the user is using ABC Bankcard we will be giving him/her a 10% discount.
So let's follow the below steps to build the Maven Drools Project
Business rules work very well to represent the logic for certain domains. They work well because they result intuitive and close to the way of thinking of many types of domain experts. The reason for that it is that they permit to decompose a large problem in single components. In this way, the user does not deal with the orchestration of all the single rules: this is the added value provided by the business rule engine.
In this article, we will discuss one specific example of an application written by using business rules. We will write the rules to decide, which email to send to the subscribers to a newsletter. We will see different types of rules and how we could express them using the Drools Rule Language. We will also see how to configure Drools (spoiler: it will be easy) and have the system elaborate on the rules to produce a result we can use.
