Understanding the concepts of Informatica ETL and the various stages of ETL process and practice a use case involving Employee database. Informatica is the most powerful data integration tool. This blog will explain what is ETL, what is Informatica and real life applications of. Class Summary Beside supporting normal ETL process that deals with large volume of data, Informatica tool provides a complete data.
Fixed and delimited flat file and XML. Informatica Domain PowerCenter has a service-oriented architecture that provides the ability to scale services and share resources across multiple machines. The Informatica domain supports the administration of the PowerCenter and Informatica services.
A domain is the primary unit for management and administration of services in PowerCenter. A node is the logical representation of a machine in a domain.
A domain may contain more than one node. The node that hosts the domain is the master gateway for the domain. You can add other machines as nodes in the domain and configure the nodes to run application services such as the Integration Service or Repository Service.
All service requests from other nodes in the domain go through the master gateway. A node runs service processes, which are the runtime representation of the application services running on a node. The Service Manager is built into the domain to support the domain and the application services.
The Service Manager runs on each node in the domain. The Service Manager starts and runs the application services on a machine. A group of services that represent Informatica server-based functionality. The application services that run on each node in the domain depend on the way you configure the node and the application service. You use Informatica Administrator to manage the domain. If you have the high availability option, you can scale services and eliminate single points of failure for services.
The Service Manager and application services can continue running despite temporary network or hardware failures. High availability includes resilience, failover, and recovery for services and tasks in a domain. Service Manager The Service Manager supports the domain and the application services. Provides notifications about domain and service events.
Authorizes user requests for domain objects. Requests can come from the Administrator tool or from infacmd. Manages domain configuration metadata.
Manages node configuration metadata. Registers license information and verifies license information when you run application services. Provides accumulated log events from each service in the domain.

You can view logs in the Administrator tool and the Workflow Monitor. Manages users, groups, roles, and privileges. Manages the connections to Informatica Analyst. Performs data integration tasks for Informatica Analyst, Informatica Developer, and external clients. Manages connections to the PowerCenter repository. Runs PowerCenter sessions and workflows.
Exposes PowerCenter functionality to external clients through web services.

Runs the Data Analyzer application. Runs the JasperReports application. Runs the Metadata Manager application.
The repository stores information required to extract, transform, and load data. It also stores administrative information such as permissions and privileges for users and groups that have access to the repository. You administer the repository through Informatica Administrator and command line programs.
The global repository is the hub of the repository domain. Use the global repository to store common objects that multiple developers can use through shortcuts. These objects may include operational or application source definitions, reusable transformations, mapplets, and mappings.
Talend for Data Integration and Big data
A local repository is any repository within the domain that is not the global repository. Use local repositories for development.
From a local repository, you can create shortcuts to objects in shared folders in the global repository.
These objects include source definitions, common dimensions and lookups, and enterprise standard transformations. You can also create copies of objects in non-shared folders.
You can view repository metadata in the Repository Manager. You can also create a Reporting and Dashboards Service in the Administrator tool and run the PowerCenter Repository Reports to view repository metadata. Informatica Administrator Informatica Administrator is a web application that you use to administer the PowerCenter domain and PowerCenter security.
You can also administer application services for the Informatica Analyst and Informatica Developer. Domain objects include services, nodes, and licenses. Manage all application services in the domain, such as the Integration Service and Repository Service.
Configure node properties, such as the backup directory and resources. You can also shut down and restart nodes.
Create and manage objects such as services, nodes, licenses, and folders. Folders allow you to organize domain objects and manage security by setting permissions for domain objects. View and edit properties for all objects in the domain, including the domain object.
You can generate and upload node diagnostics to the Configuration Support Manager.
Informatica Introduction tutorial and PDF training Guides
In the Configuration Support Manager, you can diagnose issues in your Informatica environment and maintain details of your configuration. Other domain management tasks include applying licenses and managing grids and resources.
Create, edit, and delete native users and groups. Configure a connection to an LDAP directory service. Import users and groups from the LDAP directory service. Create, edit, and delete roles. Roles are collections of privileges. Privileges determine the actions that users can perform in PowerCenter applications. Assign roles and privileges to users and groups for the domain and services.
Create, edit, and delete operating system profiles. An operating system profile is a level of security that the Integration Services uses to run workflows. The operating system profile contains the operating system user name, service process variables, and environment variables.
You can configure the Integration Service to use operating system profiles to run workflows. Domain Configuration The Service Manager maintains configuration information for an Informatica domain in relational database tables. The configuration is accessible to all gateway nodes in the domain. Domain metadata such as the host names and the port numbers of nodes in the domain.
The domain configuration database also stores information on the master gateway node and all other nodes in the domain. Includes CPU usage for each application service and the number of Repository Services running in the domain.
Information on the native and LDAP users and the relationships between users and groups. Information on the privileges and roles assigned to users and groups in the domain. Each time you make a change to the domain, the Service Manager updates the domain configuration database. Julio Rafael. Sudeep Pratap Singh. Guillermo David. Ivan Georgiev. Ausberto Acevedo.

Informatica has got the the ability to convert raw collection of data to one useful data that can be applicable to all. Informatica is a broadly used ETL Extraction, Transformation and Loading tool for extracting the source data and loading it into the target after applying the needed transformation.
Informatica Powercenter does majorly the job of Data integration. The most recent version of Informatica PowerCenter is 9. The following are the different editions for the PowerCenter: Standard edition Premium edition Advanced edition The parts within Informatica help in extracting data from its source, changing it as it concerns business needs and loading it into a target data warehouse.
Informatica makes use of service driven architecture that has the ability to share services and resources among several machines.Manages connections to the PowerCenter repository. Let us now understand the steps involved in the Informatica ETL process. You will be prompted asking the name of your mapping.
A worklet is an object that groups a set of tasks. It is a easy to use tool where it has got simple visual interface like visual basics. The Informatica domain is the primary unit for management and administration within PowerCenter.
The Session task is based on a mapping you build in the Designer.
