I want to implement a central spring boot application that responsible for designing business rules with Drools. Here is an example for integrating spring boot with drools. I need to use a UI designer for generating rules in database(rather than drl file), But I don't know how it's possible. I've searched a lot and seen somethings like drools workbench , KIE server, Guvnor and ..., but I don't know what are they and which one is suitable for me. Is there any resources or good documentation for using drools UI in Spring boot application?

I've needed to implement a rules engine, I've searched and choose between Camunda DMN and Drools. I would like to recommend you to use Camunda DMN. It's much more easier to use for rules than Drools.
Camunda DMN has a Spring Boot - starter too.
Camunda has an App (Camunda Modeler) where you can define rules with a simple to use GUI and then deploy them to your Camunda Server. They will be stored in a database. If you want you can integrate your application with another database, so that you can download rules from your Camunda Server and then store them in your Application Database.
A very good and simple example of using Camunda DMN with Spring Boot:
spring-boot-camunda-dmn-example
So looks a simple DMN-rule. It will be stored in XML-Format and you can store it as a String in your Database.
