RE: Explain the informatica Architecture in detail...

informatica server connects source data and target data using native

odbc drivers

again it connect to the repository for running sessions and retriveing metadata information

Re: Explain the informatica Architecture in detail

When we install the informatica powercenter, the following components gets ionstalled1) powercenter clients2) Integration service3) powercenter Repository service4) powercenter Repository5) powercenter Domain6) powercenter Administration console

1) powercenter clients : powercenter clients are further divided into following developer tools and they are as a followsa) Designer: It's a graphical user interface component which depicts the data flow diagram from sources to target and this designer basically performs ETL plan called mapping.b) workflow manager: This is a graphical user interface client components which helps us to create the powercenter objects1) creates sessions for the mappings2) creates workflows for each sessionc) workflow monitor: workflow monitor is a user interface client component which helps us to

monitor the sessions and workflows and even helps us to check the status of sessions and workflows. More importantly one can fetch session log through workflow monitord) workflow manager: The workflow manager is a graphical user client administrative tool which does the following tasks#1) create, edit and delete the folders2) it assigns permissions and privileges

2) Integration service:Intergation service is the etl engine that performs extraction, transformation and loading. it's also called as a heart of ETL engine because it's the tool ehich move the data from sources to target

3) Repository service: The repository service manages connectivity between repository and client application tools. The repository service is a multi threaded process, it inserts,updates,deletes the metadata in the repository

4) Repository: it's a relational database which stores all the metadata related information in the repository like source, target,session workflow session log etc related metadata

5) Domain: The powercenter domain is primary unit for managing and administrating the powercenter services like integration service and repository serviceThe powercenter is a service oriented architecture, that provides the ability to scale the services and share the resorces across multiple machines.

6)Administrative console: it's a web based client application which manages the domain
