Metadata Exchange Power Analyzer Super GluePower Center & Power Mart: Power Mart is a departmental version of Informatica forbuilding, deploying, and managing data warehouses and data marts. So lets go straight to development inInformatica.Informatica > Beginners > Informatica Product OverviewInformatica Product LineInformatica is a powerful ETL tool from Informatica Corporation, a leading provider ofenterprise data integration software and ETL softwares.The important products provided by Informatica Corporation is provided below: Power Center Power Mart Power Exchange Power Center Connect Power Channel Sources TargetsStandard: RDBMS,Flat Files, XML, Standard: RDBMS,ODBC Flat Files, XML, ODBCApplications: SAPR/3, SAP BW, Applications: SAPPeopleSoft, Siebel, JD R/3, SAP BW,Edwards, i2 PeopleSoft, Siebel, JD Edwards, i2EAI: MQ Series,Tibco, JMS, Web EAI: MQ Series,Services Tibco, JMS, Web ServicesLegacy: Mainframes(DB2, VSAM, IMS, Legacy: MainframesIDMS, Adabas)AS400 (DB2)AS400 (DB2)(DB2, Flat File) Remote TargetsRemote SourcesThis is the sufficient knowledge to start with Informatica. Informatica PowerCenter Server:Server is the place, where all the executions take place.Server makes physical connections to sources/targets,fetches data, applies the transformations mentioned in themapping and loads the data in the target system.This architecture is visually explained in diagram below: This can be treated asbackend of Informatica.3. All the client tools and Informatica Server fetch data from Repository.Informatica client and server without repository is same as a PC without memory/harddisk,which has got the ability to process data but has no data to process.
