Informatica Architechture

      Informatica has Service Oriented Architecture(SOA). It means Informatica provides its all functionality in form of services which can be scale across multiple machines.

Informatica Architechture

PowerCenter includes the following components:

1. Informatica domain. The Informatica domain is the primary unit for management and administration within PowerCenter. The Service Manager runs on an Informatica domain. The Service Manager supports the domain and the application services. Application services represent server-based functionality. The domain supports PowerCenter and Informatica application services. PowerCenter application services include the PowerCenter

Repository Service, PowerCenter Integration Service, Web Services Hub, and SAP BW Service. Informatica Services include the Data Integration Service, Model Repository Service, and the Analyst Service.

2. PowerCenter repository. The PowerCenter repository resides in a relational database. The repository database tables contain the instructions required to extract, transform, and load data.

3. Informatica Administrator. Informatica Administrator is a web application that you use to administer the Informatica domain and PowerCenter security.

4. Domain configuration. The domain configuration is a set of relational database tables that stores the configuration information for the domain. The Service Manager on the master gateway node manages the domain configuration. The domain configuration is accessible to all gateway nodes in the domain.

5. PowerCenter Client. The PowerCenter Client is an application used to define sources and targets, build mappings and mapplets with the transformation logic, and create workflows to run the mapping logic. The PowerCenter Client connects to the repository through the PowerCenter Repository Service to modify repository metadata. It connects to the Integration Service to start workflows.

6. PowerCenter Repository Service. The PowerCenter Repository Service accepts requests from the PowerCenter Client to create and modify repository metadata and accepts requests from the Integration Service for metadata when a workflow runs.

7. PowerCenter Integration Service. The PowerCenter Integration Service extracts data from sources and loads data to targets.

8. Sources.The PowerCenter can have relational database, flatfile, Application, mainframe as a source.

9. Targets. Then PowerCenter can load data into relational database, flatfile, Application, mainframe etc.

These all are the components of the Informatica SOA.
