A universe is a file that contains the following:
• Connection parameters for one or more database middleware.
• SQL structures called objects that map to actual SQL 
structures in the
database such as columns, tables, and database functions. 
Objects are
grouped into classes. Objects and classes are both visible 
to Web
Intelligence users.
• A schema of the tables and joins used in the database. 
Objects are built
from the database structures that you include in your 
schema. The
schema is only available to Designer users. It is not 
visible to Web
Intelligence and Desktop Intelligence users.
