| Dear User. A datawarehouse is a repository(centralized as well as distributed) of Data, able to answer any adhoc,analytical,historical or complex queries.Metadata is data about data. Examples of metadata include data element descriptions, data type descriptions, attribute/property descriptions, range/domain descriptions, and process/method descriptions. The repository environment encompasses all corporate metadata resources: database catalogs, data dictionaries, and navigation services. Metadata includes things like the name, length, valid values, and description of a data element. Metadata is stored in a data dictionary and repository. It insulates the data warehouse from changes in the schema of operational systems.In data stage I/O and Transfer , under interface tab: input , out put & transfer pages.U will have 4 tabs and the last one is build under that u can find the TABLE NAME .The DataStage client components are:AdministratorAdministers DataStage projects and conducts housekeeping on the serverDesignerCreates DataStage jobs that are compiled into executable programs DirectorUsed to run and monitor the DataStage jobsManagerAllows you to view and edit the contents of the repository.Sould ypu need any further assistance pls revert to this mail id venkatdba2000@yahoo.com or venkata.veluri@gmail.comRegardsVenkat |
