PEGA Introduction

                                           PEGA

What is meant by PEGA?

                                   PEGA is a business process management tool (BPM) that primary focuses on work flows or integrations capabilities.

PEGA PRPC (Pega Rules Process Commander)

                                  PegaRules Process Commander is a software product by using which we build and developing the application and deploy.

BPM+BRE = PRPC 

BPM(Business process management )

                           BPM is a methodology(set of instructions) to manage process and work flows in an organization.BPM which provides the ability to have end-to-end visibility and control over all parts of multi stepped transaction that spans multiple application and multiple people in one or more organization.

 FOR EXAMPLE :

                            ATM CARD FLOW CHART 

                                                           START

                                                                |

                                            PUT The card in ATM machine 

                                                                 |
                                             Enter the PIN number

                                                                |                match

                                             Verify the pin number ----------- Process the transaction 

                                                                | un match                            | 

                                                           END                                      END 

        This is called End-To-End process.

                                In above flow chart one transaction perform different task. In a BPM implement unit of work represent it in the form of flow diagram.

                                   

                             Development representation of unit of work in the form of flow diagram by dividing into multiple steps at each and every step going to perform a task. This is what a multiple step transaction in BPM.

                              

                                  So many BPM tools are available in market like ORACLE BPM, IBM BPM, AL BPM, LOMBARD, TIBCO. When compare to the other BPM tool PEGA is most advanced tool.

                                We can develop an application in JAVA, .NET. C ........... etc. In java lot of coding is required. But we develop a application in PEGA no need to write a single line of code every thing is generated automatically.  PEGA back end is developed by using java language.

BRE( Business Rule engine)

                            BRE is a software system that executes one or more business rules in a run time product environment.

     

Traditional Application Development VS BPM Application development 

Traditional Application development:

                                    They are three layers 

                                           User interface Layer

                                            Logic Layer 

                                            Database Layer

When we develop application in programming language we design UI, define logic and access data keeping all these elements are separate for re-usability.

BPM Application development  

                               We have to develop

                                    UI Layer

                                    Business Logic    { All these three integrated to work flow or process in BPM}

                                     Data Base

 First implement a flow we need to add every thing into the work flow.When we access the BPM Application first it will trigger the flow. Work flow trigger the ' START ' position to 'END' position based on the decision.

 In BPM tool we have 

                 
                                  Enterprise Level Scalability
                                  Standard based User Interface
                                  Integration with other business platform                                   

Process:

            Process is unit of work that can be completed either by acceptances or rejection.

                                    

                        To developed an application we need an IDE. For example Applications developing by using JAVA we need ECLIPSE IDE for .NET we need MICROSOFT VISUAL STUDIO like that in a BPM we need a IDE to develop application called BPM SUITE.

BPM SUITE:

                       BPM suite is environment which design develop the application and deploy the application by considering Build-in business rules.

BUSINESS RULES:

                                For example :

Considering the financial transaction business process for credit card. the simple business rule is. The total amount can due by a customer should not excite customer credit limit 

                                 EX: my credit Card limit is 3 Lakhs

                            I purchased up to 4 Lakh it immediate stop it says yours transaction limit is 3lakh it will decline. 

                           Here 3Lakh limit is business rules. All the Business Rules will be saved in a DB called "Business Rules DataBase"(it holds the business rules).When we access the card it will go to the database and get the business rules.

                            PRPC has building blocks that are common to most business process management application.
