Creating the Target Definition

In this lesson, you import an XML schema and create a custom view based on the schema. The custom XML target definition you create meets the following criteria:

Each department has a separate target and the structure for each target is the same.

Each target contains salary and department information for employees in the Sales or Engineering department.

Because the structure for the target data is the same for the Engineering and Sales groups, use two instances of the target definition in the mapping. In the following steps, you import the Sales_Salary schema file and create a custom view based on the schema.

In the Designer, switch to the Target Designer.
