Model query subjects

Model query subjects are not generated directly from a data source but are based on query items in other query subjects or dimensions, including other model query subjects. By using model query subjects, you can create a more abstract, business-oriented view of a data source.

Usually, model query subjects are created in the business view, not the import view. For information about the business view, see Organizing models.

Because model query subjects are based on the metadata in your model, they let you

• Reuse complex SQL statements that exist in the model
• Reference objects from different data sources in the same query subject

If you import a model query subject from another model, the model query subject will not work unless you also import the data source query subjects that the model query subject references.

If you want to edit the SQL, you must convert the model query subject into a data source query subject.
