7. Click OK to create the data source.

8. Find your new data source in the    Database   tool window   .

* For more information about the Database tool window , see the corresponding [reference topic](database-tool-window.html). > **Tip:** > To see more schemas under your new data source node, click the N of M button and select the ones you need.
