Modifying a Data Source Definition

You can add and remove resources or re-introspect a data source that is used in a Discovery model, but you must reindex and rediscover relationships in the data source, and then refresh the model.

To modify a data source

1.

Open the data source in Studio.

2.

Optionally, add or remove resources:

Select the Info tab, scroll down, and click Add/Remove Resources.

Select or clear the resources you want to add or remove.

Studio displays the changes you have made.

Click Finish to proceed with introspection and these changes.

3.

If necessary, re-introspect a data source.

Note: Re-introspection does not mean that metadata has changed. You need to reindex and rediscover relationships after re-introspection finds changes to resources that you are interested in modeling.

4.

To re-index and rediscover relationships for the data source at this time, select the Relationship Discovery tab and click Scheduler (see Running Indexing and Relationship Discovery, for more information.
