HI
Metadata is nothing but the data about data , if you take term of informatica in that through metadata only you will be converting or solving the problem. In the flow of Informatica mapping real data will first convert in to metadata which is not actual data and then it will be converted to again metadata to data , that is the way how metadata works in datawarehouse.
Data Dictionary is the tool where you can find views,tables,restrictions,alias and etc data base activities in perticular datawarehouse. |
