When you drop a table onto the
workspace, the data builder connects to the SAS Metadata Server to determine the column names
and
data types for the table. When you drop a subquery onto the workspace, the data builder makes
the same request, but determines the column names and data types for the
output table of the subquery.
You (or an administrator) must register a table in
metadata before using it as a
source table for data preparation. When you import data from a file, a database, Facebook, Google
Analytics, or Twitter, the data builder automatically registers the data in metadata
as a table. Source tables can also be registered using SAS Visual Analytics Administrator
or SAS Management Console.
