At present, the company has a sales database, it is roughly: commodity number date - sales - sales quantity
I now want to build a database: he is commodity number name of commodity -- -- -- -- - commodities specification -- -- -- -- -- - price -- -- -- -- -- - sales date - sales quantity
Because the company database can not arbitrarily changed, I think the Teradata whether can realize: establishing a database, the database part number (e.g., sales) completely reference other database content?
Two databases on commodity Numbers match
