You can create a data subset from relational, flat file, and XSD sources.
To create a data subset, you define one or more of the following components:
Entity
Defines a set of tables that are related based on physical or logical constraints. Create an entity when you need to copy data from related tables to a subset database. When you create an entity, select parameters to filter data in columns that you want to include in the subset database. You can manually create an entity or use an entity from profile results. Applicable for relational and flat file sources.
Group
Defines a set of unrelated tables. Create a group when you need to copy data from one or more unrelated tables to a subset database. Applicable for relational and flat file sources.
XSD Files
To create a data subset from an XSD source, you apply subset criteria to one or more elements or objects in the XSD file and define the scope of the criteria. Criteria determines the filter that you apply to an element or attribute. You can apply one filter for each hierarchy. The scope determines the level at which you apply the filter. The level at which you apply the criteria affects the outcome of the data subset operation.
After you apply the criteria and define the scope of the criteria, add the XSD file as the subset component to a plan.
