Mastering JBoss Drools 6

By: Mariano De Maio, Mauricio Salatino, Esteban Aliverti

Overview of this book

Mastering JBoss Drools 6 will provide you with the knowledge to develop applications involving complex scenarios. You will learn how to use KIE modules to create and execute Business Rules, and how the PHREAK algorithm internally works to drive the Rule Engine decisions. This book will also cover the relationship between Drools and jBPM, which allows you to enrich your applications by using Business Processes. You will be briefly introduced to the concept of complex event processing (Drools CEP) where you will learn how to aggregate and correlate your data based on temporal conditions. You will also learn how to define rules using domain-specific languages, such as spreadsheets, database entries, PMML, and more. Towards the end, this book will take you through the integration of Drools with the Spring and Camel frameworks for more complex applications.

Summary


In this chapter, we covered the main classes that we will be using to bootstrap, configure, and manage our Rule Engine instances. The first half of the chapter covered how different approaches can be used to define the rules that will be available to each rule engine instance. We also took a look at how Drools can load everything from the classpath and how the KIE-CI module can be used to delegate the KieModules resolution into Maven. We also covered how important the hierarchical structures of KieModules are and how they can be used to group different set of rules so that they can be loaded in the same container, to be used together. The second half of the chapter covered how to update our business knowledge (rules, processes, and so on) using the KieScanner to update the modified assets. This is a quite common requirement due the fact that we need to be able to update the business knowledge quickly so that we can adapt and deal with real-life business changes.
