FREE IPC PowerCenter Architecture & Components Questions and Answers

Question 1

What is the primary function of the Informatica PowerCenter Repository?

Accepted Answer

To store metadata and definitions

Answer

The Informatica PowerCenter Repository is a central and critical component that serves as a metadata catalog for the entire PowerCenter environment. It stores all the definitions and metadata for sources, targets, mappings, transformations, workflows, and sessions created by developers. This centralized storage ensures consistency, reusability, and efficient management of all ETL processes.

Question 2

Which component of PowerCenter manages the execution of workflows and sessions?

Accepted Answer

Integration Service

Answer

The Informatica PowerCenter Integration Service is the core execution engine responsible for running workflows and sessions. It connects to source and target systems, extracts data, applies the transformation logic defined in mappings, and loads the processed data. Essentially, it performs the actual data integration and ETL tasks as orchestrated by the workflow.

Question 3

What role does the Repository Service play in PowerCenter architecture?

Accepted Answer

Manages connections to the Repository

Answer

The Repository Service in Informatica PowerCenter is responsible for managing the connection and interaction between PowerCenter client tools (like Designer, Workflow Manager) and the Repository database. It handles all requests to store, retrieve, and manage metadata within the repository. This ensures consistent access, integrity, and version control of all ETL definitions and objects.

Question 4

Which client tool is used to design mappings in PowerCenter?

Accepted Answer

Designer

Answer

The Informatica PowerCenter Designer is the dedicated client tool used by developers to create and design mappings. Within the Designer, users define source and target definitions, drag and drop various transformations, and connect them to visually construct the data flow logic. It is the primary interface for building the core ETL transformation blueprints.

Question 5

What is a workflow in Informatica PowerCenter?

Accepted Answer

A collection of tasks and their execution sequence

Answer

A workflow in Informatica PowerCenter is an organized sequence of tasks that are executed to achieve a specific data integration goal. It orchestrates the execution of various components, including sessions (which run mappings), command tasks, email notifications, and other control tasks. Workflows define the overall process flow, dependencies, and scheduling for ETL operations.
