Data Subset Extraction using Referential Integrity and Combined Data Elements

In this tutorial, you import class information using referential integrity for a DB2 data store. Then you create a method RIMETHOD to use a combined data element.

A combined data element is essentially a dummy data element that you create for ease of use when it comes to manipulating classes. Once a combined data element is created, you can perform operations against the data element like you would for other elements.

Note: Sessions in this tutorial should be done in order.

This tutorial walks you through the data classification and the data subsetting phases. In this session, subsetting is based on referential integrity rules.

Begin this session only after you have completed the DB2 Data Stores Session for the tutorial Simple Data Subset Extraction. You must already be logged in to Data Builder to begin.

In this session, you:

Import referential integrity classes.
Assign estimated classes.
Verify combined data element information.
Create a referential integrity method.
Edit method properties.
Submit a JCL to create the test environment.
