Selecting a Minischema Option for Relational Sources

In the Select Minischema page of the Connection Wizard, you can perform the following actions:

Note:

If you are accessing a relational data source, you can also select the “Use Introspection to Detect Hierarchies” option when you choose to create a new minischema diagram. Selecting this option provides a deeper inspection of the data source to return more details, such as hierarchy information. If you are accessing a flat or text file data source, the “Use Introspection to Detect Hierarchies” option is not available.

Reuse an existing minischema diagram, with an option to clear the existing schema.
See Reusing an Existing Minischema for Relational Sources.
Skip creation of a minischema diagram.
See Skipping Minischema Creation for Relational Sources.
Complete the data source connection process using introspection.

Note:

If you are accessing an Oracle BI EE data source, you may create a minischema, but it can contain only self joins (joins between columns in a single file).
