    Metadata is data about data. E.g. if in data mart we are receiving any file. Then metadata will contain information like how many columns, file is fix width/limited, ordering of fields, data types of field etc.



    metadata is data about data..it contains information about the cardinality etc..cardinality is nothing but number of attributes

    Metadata is structured information
    that describes, explains,
    locates, or otherwise makes it
    easier to retrieve, use, or manage
    an information resource. Metadata
    is often called data about data or
