2.   This concept is a formal approach for identifying the rules that encapsulate the structure, constraint, and control of the operation as a one package  Business Rules declare business structure or behavior of the business  Business rules describe the operations, definitions and constraints that exist in an organization  They include policies, requirements, and conditional statements that are used to determine the tactical actions that take place in the applications and systems Business Rules

3.   They always resolve to true or false  They are atomic  They define the rules clearly and make sure that rules don’t conflict Business Rules' Features

4.   Static A constraint or derivation rule that is applied to each individual state of the business  Dynamic A rule that is concerned to a request of actions in response to events Business Rules’ Groups

5.   Business rule could show the computation of taxes for each employee’s wages  When Each employee gains less that $….. monthly Then Taxes is 0. Business Rules- Example

6.   A statement of business rules falls into one of four categories: Definition of business terms Facts Constrains Derivations Business Rules Categories

7.   A software system that executes a set of business rules that may come from several sources  Business rules are components of business rules engine Business Rules Engine

8.   It might be executed in two different methods such as:  Forward chaining This method typically starts with the available data and uses rules to extract more data until a goal is reached  Backward chaining This method typically starts with a list of goals or a hypothesis and works backwards from the consequent to the antecedent to search for available data that will support any of these consequents Business Rules Engine’s Types

9.   A software system that is used to deploy, monitor and maintain the variety and complexity of the business rules that are used by operational system within an organization  Business rules engine is generally provided as a component of business rules management system Business Rules Management system

10.   It includes, at least: A repository, storing decision logic to be externalized from application code Tools, using by both technical developer and business experts to define and manage business rules A runtime environment applications, using business rules engine, can execute and manage business rules within BRMS Business Rules Management System

11.  DROOLS

12.   A software system includes several projects which is prepared by Jboss company  Business Rule Management System  It has been implemented based on Charles Forgy’s Rete algorithm  It is written in java DROOLS (cont.)

13.   It provides Declarative Programming  It is flexible enough to match the semantics of all problem domains with Domain Specific Languages (DSL) via XML using a schema to define the problem domain  It introduces the Business Logic integration Platform which provides a unified and integrated platform for Rules, Workflow and Event Processing DROOLS (cont.)

14.   It consists of several project: Drools Guvnor (business rules manager) Drools Expert (rules engine) Drools Flow (process/workflow) Drools Fusion (event processing/temporal reasoning) Drools Planner (automated planning) DROOLS - Projects

15.   It is a business rule manager which is a combination of core drools and other tools  A business rules manager allows managing rules in a multi-user environment with user friendly interfaces  Guvnor is a web and network components for managing rules Drools Guvnor

16.   Drools Expert is a declarative, rule based, coding environment  This allows users to focus on "what they want to do", and not the "how to do this".  It uses the AI concepts for defining rules ( knowledge Representation, Reasoning, and Expert System) Drools Expert

17.   It provides workflow to the Drools platform  A workflow or business process shows the order of execution of several steps, Describes a complex composition of different tasks  Drools Flow empowers end users to specify, execute and monitor their business logic Drools Flow

18.   It is the module which is in charge of the enabling of the event processing capabilities  An event processing concept deals with the processing of multiple events with the goal of identifying the meaningful events among the all events  Event processing uses some techniques such as detection of complex patterns of many events, event correlation and abstraction, event hierarchies, and relationships between events Drools Fusion

19.   Drools Planner optimizes planning to do more business with less resources.  For example Every organization faces planning problems such as provide products or services with a limited set of constrained resources (employees, assets, time and money)  It solves use case, such as Agenda scheduling, Educational timetabling, Job shop scheduling and so on. These use cases are probably NP-complete, this means It's easy to verify a given solution to a problem in reasonable time, but it might not be an optimal solution Drools Planner

20.   Home theater control  smartphone as a remote control  Smart Keyboard remote Harmony Remotes

21.  Thank you
