Now that we've been introduced to the Design Center, it's time to make use of it to import or define the metadata about our source database objects. Metadata is data that describes our data. We are going to tell the Warehouse Builder what our source database objects look like and where they are located, so that it can build the code necessary to retrieve the data from them when we design and run mappings to populate our data warehouse.
