Pega – Business Process Management

As you all know BPM stands for Business Process Management. The immediate question that comes to mind is what a Business Process is?

Wikipedia defines (http://en.wikipedia.org/wiki/Business_process  as follows, which is quite easy to understand


A business process or business method is a collection of related, structured activities or tasks that produce a specific service or product (serve a particular goal) for a particular customer or customers. It often can be visualized with a flowchart as a sequence of activities with interleaving decision points or with a Process Matrix as a sequence of activities with relevance rules based on the data in the process.
Let’s see easier definition of BPM 

BPM is the general term for the services and tools that support explicit process management (such as process analysis, definition, execution, monitoring and administration), including support for human and application-level interaction.


In other words a BPM can be treated as a set combination of 


BPM = P2P + A2A + P2A 


(P2P – Person to Person, A2A – Application to Application, P2A – Person to Application). 


When we define a BPM the set of component that completes the BPM architecture. Although most of the components are self explanatory below listed with few one liner description


• Workflow: A workflow is a depiction of a sequence of operations, declared as work of a person, work of a simple or complex mechanism, work of a group of persons, work of an organization of staff, or machines.


• Portal: Portal is a web system that provides the functions and features to authenticate and identify the users and provide them with an easy, intuitive, personalized and user-customizable web-interface for facilitating access to information and services that are of primary relevance and interests to the users.

• Operational Data Analysis : Operational business intelligence (BI) is a system of reports, metrics, and dashboards designed to drive decisions that optimize a company’s performance in the present.


• Integration: In the BPM context – Integration means linking all the various layers of BPMS architecture seamlessly as well as with other systems that form part of Business process domain . 


• Document Management: In information systems, Document management consists of Digitizing, Indexing, Archiving , Retrieving and Managing documents.


• Identity Management: In information systems, identity management is the management of the identity life cycle of entities (subjects or objects)


• Rules: A business rules engine (BRE) is a software component that allows non-programmers to add or change business logic in a business process management (BPM) system.

• Process Repository: In the BPM context – Process Repository is the collection of Process models – Design time, completed and run time . Typically they are stored as XML models compliant to standards like BPMN. 


• Process services : 
• Monitoring (Business Activity Monitoring BAM ) :
• Lifecycle Management :
• Security :
• Event Management :
• Process Documentation :

• BPM
• Procedural processing through a user-interactive BPM / BPMS(BPM Suite) tool.
• BRE
• Declarative “On-Change” processing through an event-driven tool.

• Software platform enabling businesses the opportunity to migrate all their disparate, diverse, and often complex business rules onto one platform.
• Ability to streamline, automate, and document business processes.
• Consolidate multi-stream processes into one system.
• Through service connectors (such as SOAP, MQ, active file listening) connect to existing enterprise applications.
• Pass data between systems and have such information parsed, extracted, and interpreted.

• Development can be achieved in small iterative-based parts
• Development is contained within heavily graphic-driven ‘Rule Forms’ that are version and ruleset controlled.
• All run-time Java code is compiled and executed by the system at run-time.
• Changes or new configurations can be tested in real-time, even on production systems without affecting other users or processes.

* gzip & gunzip ( *.gz ) 
* bzip2 & bunzip2 ( *.bz2 )
* zip & unzip ( *.zip )

gzip : The compress program


-d    Uncompressing a “gzipped” file  (  gunzip  <==> gzip -d  )
-r    Recursive compression 


tar : The archival program

For creating a disk archive that contains a grp of file or an entire dir structure.
tar option

-c       Create an archive
-x       Extract file from archive
-t       Diaplay files in archive 
-f arch     Specify the archive arch

Creating an archive ( -c )
$ tar -cvf archive.tar file1 file2      ( c – create, v – diaplay list , f – specify the name )

Extracting an archive ( -x )
$ tar -xvf archive.tar

Viewing the archive ( -t )
$ tar -tvf archive.tar 


 zip & unzip : Compressing and archiving together   


$ zip archive.zip file1 file2 file3
$ unzip archive.zip

-r    ecursive compression
-v    viewing the archive

Here r the 2 lines from a DOS file, atul, viewed on a unix system with the vi editor :

Line 1^M
Line 2^M

$ od -bc atul   { this command is used to check the CR-LF in file }

There is a ^M ( ctrl – m ) representing the CR sequence at the end of each line. An octal dump confirm this :
The CR-LF combination is represention by the octal value 015 -012 and the escape sequesnce rn. Conversion of this file to UNIX is just a simple matter of removing the r. This is often done automatically when downloading a UNIX file from windows machine using ftp, but sometimes u have to do it yourself.

$ dos2unix atul.dos atul 
$ unix2dos atul.dos atul

* unix2dos inserts CR before every LF, and thus increase the file size by the no of line in the file.
* You can use dos2unix to delete the ^M char that occurs at the end of every line in the file typescript.
* If u view the unix file atul on windows using notepad but without performing the conversion then you’ll see a single line : Line 1Line 2. In fact, whenever you see a single line on a windows machine that should have been multiple line.
* Never perform this conversion on a binary file.

“script” command is use to record your Unix session, whatever you are typing on terminal, whether it is input or output, is recorded in a file “typesctipt”

$ script
   Script started, file is typescript
$         { Anothe shell, child shell of login shell }
$ exit  ( ctrl -d )

Script done, recorded file is typescript.

  You can also use
    script -a              ( append in the existing file )
    script logfile        ( create a logfile of your session )

tips ::
* Whenever use “script” always give the output filename like
         $ script record1  or script record2

* Otherwise, when you are using “script” command second time, it will overwrite the first one output file   

There are four distinct modes of this search. The two most useful are “My most recent rules” and “Rule content.” The latter looks across all rules for a name. You could go to Edit->Preferences and set the number of returned hits to the highest number allowed for your version of Pega
