Rule, case, process, class, and ruleset are the main building blocks of applications in Pega. Rules define specific behaviors, cases represent business transactions, processes define how work items progress, classes contain related rules and data, and rulesets group related classes and rules. Designer Studio is the interface that allows users to build and manage applications, with components like the header, explorer panel, work area, and developer toolbar.

1. What is Rule in Pega?
 Rules arethe building blocks of applications
 A Rule type is a concrete class derived from the Rule- baseclass.
 A Rule is a named object that defines the behavior of part of an application
 A Rule is a single instance of a class derived fromthe Rule- class
 Example: Rule-Obj-Property is a Rule Typeand a Property named User
Name is Rule
What is Case?
 A business transaction thatis initiated, processed, and resolved
 A case typically consists of assignments, processes, businesspolicies, and
potentially other cases
 A case is a instanceof a concrete class (Case Type) derived fromWork-
Cover- class
Example: Purchaserequest
What is Process?
 Process is represented as Flow in PRPC
 Process or Flow defines:
– How work items are created
– How they progress through oneor moreflow executions
– How they become resolved (completed)
 Example: Loan lending process

2. What is Class?
 Class is a container of Rules like Properties, Sections, Flow actions, Data
Transformand many other rules
 Many Rules apply to a specific class, and potentially to subclasses of that
Class
 Classes can be Abstract or Concrete
– AbstractClass is only a container of rules and data and cannot be
persisted in database
– Concrete Class contain rules and data and it can be instantiated and
persisted in database
– Concrete Classes may inherit froman AbstractClass
Class Hierarchy is a hierarchy for storing Rules and Data in PRPC
What is Rule Resolution?
 Rule resolution is internal search algorithm that the systemuses to find the
best or most appropriaterule
 This algorithm uses many factors like Rule Name, Applies To Class, Rule set
etc.,
Example: A property named FullAddress is present in Person Class and Location
Class. While capturing a person’s address information, systemwilluse FullAddress
property fromPerson Class.
What is Inheritance inPega:
 Inheritancedefines the association between classes
– Parent Class
– Sub-Class/Class
 Pega provides two types of Inheritance – Pattern and Directed

3. – Directed Inheritanceis defined by User
Pattern Inheritanceis enforced by the Systembased on Class Name
Class Hierarchy: Example
What is Ruleset inPega?
 Ruleset is a container of rules
 All rule type mustbelongs to a Ruleset.
 Purposeof ruleset as container is different
– Access Control
– Migration
– Versioning
 Ruleset is a bigger container than a class
Contains related classes and rules

4. Ruleset Name &Ruleset Version:
 Ruleset has 2 parts – Ruleset Name & Ruleset Version
 Ruleset Name
– Maximum 64 characters
– Ex. PolicyAdmin
 Ruleset Version
– Has 3 parts separated by a hyphen – Major, Minor & Patch
– Ex. 01-05-07
What are Components in Pega Designer Studio?
 Designer Studio
– Header
– Explorer Panel
– Work Area
– Developer Toolbar
What is Designer Studio:
 High-productivity portalfor application designers
 Launched from any browser
 Steps to view Designer studio :
1.Launch the Pega server URL
2. ProvideUsername and Password
3.Launches Designer Studio with features based on access group

5. Components
– Header – Global access to the application via wizards, tools and
landing pages
– Explorer Panel – Organizesimilar actions and tools to keep architects
focused and efficient
o Provides navigation mechanismto access application records
– Work Area – Main workspacefor architects
– Developer Toolbar – Provides tools for debugging, performance
analysis, and understanding how an application is built.
Types of Explorers inDesigner Studio:
Recent Explorer:
 View, open and search the recent items opened in the Work Area.
 Available as “Recent Items” in Header
Case Explorer:
 Reviews and updates the application’s casehierarchy
 Replaces functionality in the Case Designer landing page
Data Explorer:
 Creates, modifies data object types and their associated data pages(Declare
Pages).
App Explorer:
 Hierarchical view of the rules in the application stack
 Application Explorer as in Pega 6.3
Records Explorer:
 Explores both Data and Rule instances
 Rules explorer in Pega 6.3

6. Private Explorer:
 Displays currently checked out rules by the operator.
 Available as “My Checkouts” in Header
Favourite Explorer:
 View, edit and open favorite rules
Pega Testing/Debugging &Performance Tools Overview:
 Tracer : Debugging tool fully cross-browser and supports severalnew event
types.
 Clipboard : In-Memory allocation displays all pages and Made Cross
browser and localizable
 UI inspector : Analyzethe User Interfaceelements
– Displays the application structurein the context of UI rules and
elements by Hover over the UI item
 Performance : Open PAL and now browser compatible
 Alerts : View alert logs in readable format
 InspectionPrefs : Enable/Disable the Declarativeand Field Value inspectors
