Step 2. Add User-Defined Fields that Demonstrate the Normalization of an Array

Step 2. Add User-Defined Fields that Demonstrate the Normalization of an Array

In this step, you add user-defined fields that invoke PowerExchange functions that demonstrate the normalization an array with multiple occurrences.
The user-defined fields invoke the PowerExchange GenVRowKey and GetSeqWithinLevel functions. These functions add data to the database row test output that demonstrate how the table properties that you defined normalize the array. When you run a database row test, PowerExchange displays one row for each occurrence in the array. For more information about these functions, see GenVRowKey and GetSeqWithinLevel.
