There are two categories of Universe: Repository Universe and JDBC Universe. For example, you can create a Repository Universe and map it for use in Ad-hoc Dashboard.

Repository Universe is for DataSources (except Composite), for backward compatibility for Repertoire. JDBC Universe is for JDBC relational datasources.

All the modules that use Universe, use the Universe name and not the path. Therefore, you can easily switch to a different Universe by re-mapping. A Universe must be given a name before it can be seen in the Ad-hoc tools. For details on Universe mapping and access control, refer to the Elixir Administration Tools User Manual .

This chapter describes how to create a Universe, work on Universe tables and more.
