what is the Informatica Architecture ?

The Power Center domain

            It is a primary unit of the Administration.

            Can have single and multiple domains.

            It is a collection of nodes and services.

Nodes

   A node is the logical representation of a machine in a domain

One node in the domain acts as a gateway node to receive service requests from clients and route them to the appropriate service and node

Integration Service:

Integration Service does the entire real job. It extracts data from sources, processes it as   per the business logic and loads data to targets.

Repository Service:

Repository Service is used to fetch the data from the repository and sends it back to the     requesting components (mostly client tools and integration service)

Power Center Repository:

Repository is nothing but a relational database which stores all the metadata created in Power Center.

Power Center Client Tools:

 The Power Center Client consists of multiple tools.

Power Center Administration Console:

This is simply a web-based administration tool you can use to administer the Power Center installation.
