Data modeling tools store data types for domains and most columns, all of which Metadata Manager extracts and stores in the Metadata Manager warehouse.
Since data modeling tools do not store data types for columns using domains, Metadata Manager cannot extract or store the data types for these columns. To help you determine the data type of columns using domains, Metadata Manager stores the data types of all domains and establishes an association between columns and their corresponding domains. To determine the data type of a column using a domain, determine the domain associated with the column, and then determine the data type of the domain.
