Drools training

Introduction to Drools training:

Drools training is a business logic integration platform. Drools training is written in Java language. Drools rules are run on Java applications, and the order of the steps to be performed is determined by the code. To achieve this, the Drools rules engine converts business rules into an execution tree. Drools is a rules business management solution system. It provides a core business rule engine, a web authoring and rules management application for core development.

Overview of Drools training: 

Drools training has an open source business rules engine that is easy to access, easy to adjust, and easy to manage. It is industry-standard, fast, and efficient. Business analysts or reviewers can use it to easily view business rules to verify that the coded rules have executed the required business rules.

Drools is a java-based rule engine, open source, which can liberate complex and variable rules from hard coding and store them in files in the form of rule scripts, so that changes to rules can be performed immediately without modifying the code to restart the machine. The environment is in effect.

About Drools training:Drools training infographic

Drools is an open source rule engine written in Java. It implements the Rete algorithm to evaluate the rules written and supports the representation of business logic. Use DSL (Domain Specific Language) language to write business rules, making the rules easy to understand and easy to learn and understand. Support for Java code to be embedded directly into the rules file.

Drools training is mainly divided into two parts: one is the Drools rule, and the other is the interpretation of the Drools rule. The compilation and operation of the rules is done through the relevant APIs provided by Drools. The overall upstream of these APIs can be divided into three categories: rule compilation, rule collection, and rule execution.

Drools is divided into two main parts: Those are Authoring and Runtime. In creation of files authoring process is involved. In the creation of working memory runtime is involved. And by using runtime the activations are handled.

 Drools is a Business Rule Management System (BRMS) solution that covers the following projects:

Drools Workbench: Business Rule Management System

Drools Expert: Business Rules Engine

Drools Fusion: Event Processing

jBPM: Workflow Engine

Opta Planner: Planning Engine

Drools Rule Engine:

Drools rule engine uses the rule based approach to implement and expert the system.

The predecessor of JBoss drools training rules was open source project called Drools. Now included in the JBoss door, renamed JBoss Rules became the rules engine for the JBoss application server.

Drools is an implementation of the rules engine for the Charles Forgy-based RETE algorithm tailored for Java. RETE with interface makes the business rules have a more natural expression.

Advantages of Drools training:

Declarative programming of Drools:

For difficult problems rules make it easy to get solutions and to get the solutions verified as well. And codes, rules are written in less complex language. These rules can easily understand by business analysts.

Logic and Data separation of Drools:

In the logic and data separation data may stay in the Domain objects, and logic may stay in the rules. This kind of separation is depending upon the kind of project. And this separation is very advantageous.

Speed and scalability of Drools:

The Rete OO algorithm is written on Drools. This algorithm is very helpful to Drools that application became very scalable.

Drools Centralization of knowledge:

By using rules, executable repository knowledge is created. These readable rules are can also maintain as documentation.

Drools Tool integration:

There are some tools used to edit. The tools like Eclipse are used to edit and manage rules and get immediate feedback, validation, and content assistance. Auditing and debugging tools are some of other tools.

Drools rule engine environment setup:

Drools is a Java based open source rules engine, so need to install the JDK   environment on the development machine before using Drools. Drools 5 requires a JDK version 1.5 or above. Download the eclipse plug-in IDE for Drools 5.

Open the links directory under the directory where eclipse 3.4 is located create a text file in the link directory, and rename it to drools-5, Open it with notepad. After the startup is complete, open the menu Window Preferences. If the Drools node can be found in the left navigation tree in the pop-up window, the Drools5 IDE installation is successful.

The rule engine is developed by the inference engine, which is a component embedded in the application, which separates the business conclusion from the application code and writes the industry using the predefined semantic module decision making, accept data input, interpret business rules, and make business decisions based on business rules.  Drools use the RETE algorithm to evaluate rules. The DREALS 6.0 (currently the latest version) also introduces the PHREAK algorithm, which allows Drools to express business logic in a declarative mode. Rules can be written in a non-XML native language for easy learning and understanding. Also, you can embed Java code directly into the rules file, which makes Drools’ learning more attractive.

Drools also have other advantages:
  • Very active community support
  • Easy to use
  • Fast execution speed
  • Popular among Java developers
  • Compatible with the Java Rule Engine API (JSR 94)
Commonly used Drools in business rules:

The rules engine evolved from the inference engine, a component embedded in the application that separates business decisions from the application code and uses predefined semantic modules to write business decisions. Accept data input, interpret business rules, and make business decisions based on business rules.

Why use the rules engine, what is the use of the rules engine (compared to the simple logic rules written by if else method) Reference: Java Rule Engine: Open Source Drools Project.

(1) The rules engine can make your system easier because you don’t have to write business logic in your code, such as how to choose stocks, choose strange combinations of conditions in the stock process, and so on.  This logic no longer enters your code. You will be able to focus on the data model.

(2) You can be more efficient by stripping out volatile business logic from your application code. Simple applications may not benefit from a rule system. But if you develop a large system with a lot of volatile business logic, you can consider integrating the rules engine into your application.

Conclusion of Drools training:

Drools training has an open source business rules engine that is easy to access, easy to adjust, and easy to manage. Drools training is a business logic integration platform.
