TutorialKart.comWhat is Informatica PowerCenter?
Informatica PowerCenter is an enterprise data integration and ETL platform used to extract data from source systems, transform it according to business rules, and load it into target systems such as data warehouses, databases, files, and enterprise applications. In many projects, the word Informatica is used informally to refer to Informatica PowerCenter, though Informatica is the company and PowerCenter is one of its data integration products.
PowerCenter is commonly used in data warehouse, reporting, migration, master data, and batch integration projects. It provides visual development tools for designing mappings, server services for running jobs, and repository services for storing metadata about sources, targets, mappings, workflows, sessions, and transformations.
Informatica PowerCenter as an ETL and data integration tool
At its core, Informatica PowerCenter performs three main ETL activities: extraction, transformation, and loading. A developer designs the data movement logic in a mapping, connects that mapping to a session or workflow, and schedules or runs the workflow through the PowerCenter services.
| ETL stage | What happens in Informatica PowerCenter |
|---|---|
| Extract | PowerCenter reads data from sources such as Oracle, SQL Server, flat files, XML files, SAP, mainframe systems, and other supported connectors. |
| Transform | The data is cleaned, joined, filtered, aggregated, validated, formatted, or derived using transformations inside mappings. |
| Load | The transformed data is written to target tables, files, warehouses, or other supported systems. |
What data extraction means in Informatica PowerCenter
Data extraction is the process of reading data from one or more operational source systems and bringing it into the PowerCenter pipeline. These source systems may include relational databases, flat files, XML files, ERP systems, CRM systems, or other enterprise applications. In a typical mapping, source definitions describe the structure of the incoming data so that PowerCenter can read it correctly.
What data transformation means in Informatica PowerCenter
Data transformation is the process of converting source data into the required target format. In PowerCenter, transformations are objects used inside mappings to apply business rules. Common transformation work includes merging, cleansing, filtering, aggregating, validating, looking up reference data, and deriving new values.
- Data merging: combining data from multiple sources into one consistent flow.
- Data cleansing: correcting, standardising, or removing unwanted data before loading it to the target.
- Data aggregation: calculating summaries such as totals, counts, minimum values, maximum values, and averages.
- Data derivation: creating new values from existing fields, expressions, or business rules.
- Data validation: checking whether values meet required rules before they are inserted into the target system.
What data loading means in Informatica PowerCenter
Data loading is the process of writing the final transformed data to the target system. In data warehouse projects, this target is often a warehouse table, staging table, fact table, dimension table, or file. PowerCenter supports both full loads and incremental loads.
- Initial load or full load: loading a complete data set into an empty or refreshed target for the first time.
- Delta load, incremental load, or daily load: loading only new records and changed records after the initial load.
How Informatica PowerCenter works in a real ETL flow
Informatica PowerCenter uses a visual development approach. Developers drag and configure objects known as transformations, connect them in a mapping, and define how data should move from sources to targets. Once the mapping is ready, it is executed through sessions and workflows. In the background, PowerCenter services read the source data, apply transformation logic, and load the result into the target.
A simple PowerCenter ETL flow usually follows this order:
- Define source structures such as database tables or files.
- Define target structures such as warehouse tables or output files.
- Create a mapping to connect sources, transformations, and targets.
- Create a session to run the mapping with execution settings.
- Create a workflow to control job order, scheduling, dependencies, and run logic.
- Monitor workflow execution, errors, rejected rows, and session logs.
Informatica can communicate with many major data sources such as mainframe systems, relational databases, flat files, XML, SAP, and other supported systems. It can move and transform large data volumes, perform joins across different sources, and load data in controlled batches. In warehouse projects, this helps teams separate data integration logic from application code.
Informatica PowerCenter architecture and main services
Informatica PowerCenter follows a client-server architecture. The client tools are used to design and manage ETL objects. The server-side services execute workflows and manage metadata. The repository stores definitions for sources, targets, mappings, transformations, sessions, workflows, users, and other configuration objects.
Informatica PowerCenter Architecture
It is a client server technology with service oriented architecture (SOA). It has separate client components and server components. But if we want to work with any client or server components, we should first start the Informatica services. So how do we start Informatica Services?
In windows Operating system, we can access Informatica services at the Informatica server location at C:\Informatica\10.2.0\tomcat\bin.
Second one is we can access Informatica services, if we configure Informatica server on windows with Services.msc file in system Administrative tools.
Third one is if we configure server and client o one machine with windows, we can get services in All Programs as shown below.
Four core components of Informatica PowerCenter architecture
The exact component names may vary by product version and installation, but a basic PowerCenter setup is usually explained through these four core parts.
| PowerCenter component | Purpose |
|---|---|
| PowerCenter Client tools | Used by developers and administrators to create mappings, workflows, source definitions, target definitions, and repository objects. |
| PowerCenter Repository | Stores metadata for mappings, sessions, workflows, transformations, users, folders, sources, and targets. |
| PowerCenter Repository Service | Manages access to repository metadata and allows client tools and services to read and write repository objects. |
| PowerCenter Integration Service | Runs sessions and workflows, reads source data, performs transformations, and loads data to targets. |
In an enterprise installation, additional services may be configured for monitoring, web services, metadata management, reporting, PowerExchange connectivity, and other integration needs.
PowerCenter client tools used by developers and administrators
PowerCenter client tools provide the graphical interface for design, execution setup, administration, and monitoring. Common tools include Designer, Workflow Manager, Workflow Monitor, and Repository Manager. Developers spend most of their time defining mappings and workflows, while administrators manage repositories, services, permissions, and operational settings.
Informatica PowerCenter services and server-side components
- PowerCenter Repository Service.
- PowerCenter Integration Service.

Not every environment uses every service in the list. A smaller PowerCenter setup may use only the services required for repository access and workflow execution, while larger environments may add services for metadata, reporting, data quality, real-time integration, or specialised connectivity.
Important Informatica PowerCenter objects
Understanding PowerCenter is easier when you know the objects used in day-to-day ETL development.
| Object | Meaning in PowerCenter |
|---|---|
| Source definition | Metadata that describes the input structure, such as columns in a table or fields in a file. |
| Target definition | Metadata that describes where the transformed data will be loaded. |
| Mapping | The main design object that connects sources, transformations, and targets. |
| Transformation | A processing object used to filter, join, aggregate, look up, route, validate, or modify data. |
| Session | Execution settings for running a mapping, including connections, commit settings, and error handling options. |
| Workflow | A group of tasks that controls the execution order, dependencies, scheduling, and run logic. |
| Repository folder | A logical container used to organise mappings, workflows, and related metadata. |
PowerCenter options and capabilities used in data projects
