Data Page is Single Page or Page list where it stores the data that system needs to populate work item properties for its calculation or for other processes. Thread – Collection of Pages Requestor – Collection of Threads Node – It associates with multiple requestors.

Browser requestor – Starts with letter ‘H’ Batch requestor – Starts with letter ‘B’ Application requestor – Starts with letter ‘A Portal requestor – Starts with letter ‘P’.

Portal is an Interface that appears for the user (Developer / End User) and portal can be configured in Access Group. Ex: Developer portal, manager portal, user portal, admin portal.

Report is a rule in pega, where it mainly used by managers to review and verify the data and also to visualise the overall progress. List view and Summary view are the popular views in pega.

Column layout, portal layout, grid layout, dynamic layout.

Abstract – It’s a rule created to support the definition of rule including other classes, it cannot be instantiated and end with ‘-‘ Concrete – It can have the instances stored in the database.

PRPC Shared Product, Enterprise Shared Product Layer, Generalised Application Layer and Organisational & specialised application layer.

Directed Inheritance – Allow user to specify a parent class (must not related to name of the class) Pattern Inheritance – It search based on the patter defined in class structure.

Workgroup – Its collection of workbasket and maintained by a manager who can allocate work to the users associated with Workgroup. Worklist – It belongs to an operator and he can access the cases based on his priority. Workbasket – It related to an organisation via Workgroup and it holds the cases which are not belongs to unique operator id.

Workgroup – by associating a workbasket monitored by manager-operator rule – Defining a workbasket in operator id rule form.

Straight through flow, Process flow, Screen flow, Starter flow and Sub flow.

By using privileges and when conditions under process tab of the flow instance.

Flow action specify the choices that users have when performing an assigned work object Connection flow action and local flow action are the two types.

Service level can define the timeline to process work object by executing activities Goal, Deadline and Passed Deadline are the terms associated with it.

Process level – It defines the SLA for overall case life cycle Assignment level – It defines the SLA for a particular assignment associated with a particular user.

Inner Join – It is used to join two tables with matching data Left Outer Join – It fetches all columns from applies to class and associated column which is having values from joined class Right Outer Join – Vice versa of Left Outer Join

Agent is an internal background process operating on a server in periodic basis Legacy, Standard and Advanced Agents are running modes.

Obj – Preferable for Pega Internal DB Tables Used to perform operations on single table at a time Can BLOB (pzPvStream) column results as well Pega automatically write sql queriesRDB – Preferable for External Tables Used to perform operation on multiple tables at a time BLOB (pzPvStream) Column values cannot be retrieved We need to define query using Connect – Sql rule and use it.

px and pz are read only keys in pega which are created while processing ex: pxObjClass, pxCreateDateTime, pzInsKey, pxRequestor py is editable key ex: pyid, pyWorkBasket.

Local Variable – It is strictly particular to one activity/Data transform and it cannot be taken forward. Parameter Variable – It associate the value of a property and we can pass the parameter value to calling rule and utilise it.

Activity is a rule where it follows a series of instruction given by sequence of steps in terms of methods. Connector, Routing, Trigger, Utility, Validation, Notify, OnChange, Parent Activity and Assign are the various types used in Pega.

Exit – Activity: It exits the calling activity and control returns to the called activity Activity – End: It Stops executing all the calling/called activities.

Locking is acquiring control over a work object before proceeding to perform any action on it and to ensure only single user to be perform actions on a work object at a time. Default Locking: Only one user can work on work object at a time. Optimistic Locking: This is enhanced feature introduced in pega 7, where multiple operators work on same object at a time.

Using Faults tab in Connect – Soap rule Using Error handle flow in Connect – Soap rule Service Tab Transition Step

a) It simplifies the search by introducing index values to the aggregated properties b) It helps in exposing aggregate properties c) Finally converts complex algorithm to simple feasible solution

By making use of Remote Tracer Functionality available in tracer and hence tracing the different requestor sessions available

Available: It is ready to run at the time of rule execution. Not Available: It is not available during run tim. Blocked: It restricts the rule resolution to not execute the rule at run time, by returning ‘Rule Not Found’ exception as well as throws error. Final: this functionality to indicate that the rule cannot be modified further, however it can be changed in the same ruleset higher version. Withdrawn: It withdraws a rule from its current version and it’s all lower versions, however if the same rule present at different Rule set version will be executed at run time.

Notify, NotifyAll, New, Work-.AddCovered, AddCoveredWork, Work-.Addwork, Work-.Add, NewCovered, ToCreateOperator, ToWorkBasket, ToWorklist, Work-.NewDefaults, Assign- .NewDefaults, CorrNew, NewDefaults.

Primary page is a page associated with the rules applies to class and it holds the property values & pairs, the same can be utilised in various places by referring it.

Clipboard: It serves as primary temporary memory for multiple requestor. Database: It is the permanent memory where the data can be persisted to make use at later point of time (Obj and RDB methods are used to interact with DB from Pega)

User Pages: Its top level clipboard page created by user by making use of activity methods such as Page-New, also it can be editable by the use. Data Pages: It is generated by executing the declarative rules and the content appears as read only to the users.

By making use of DB Table Class Mapping Wizard

Control initiates an entry in the pr_sys_locks table Finally pxLockHandle holds the lock object (i.e., pxLockHandle = pxObjClass + Lock key array) Note: When different requestor tries to obtain a lock on same object, then insert query fails and throws error.
