Begin introspection by selecting a data source to examine and then choosing a minischema option.
To begin introspection and choose a minischema option:
In the Source Navigator, right-click the data source on which you want to perform introspection, and select Introspect.
Create a new schema diagram—If you choose this option, enter a name for the new minischema.
Reuse an existing minischema diagram—If you choose this option, select the minischema to reuse. To clear the content of the minischema before you begin, select the Clear existing schema check box.
Skip creation of a minischema diagram—If you choose this option, you still are guided through the introspection process, but you will not create a minischema diagram.
Note: | If you are accessing a text file data source, you may create a minischema, but it will not contain joins. |
Ensure that Use Introspection to Detect Hierarchies is selected.
Click Next; or, if you chose not create a minischema, click Finish.
Clicking Next takes you to the Select Fact Tables page of the wizard, as described in Populating a Minischema for Relational Sources.
