The DataSet is a relational structure that can be easily traversed and manipulated when you
parse the XML string retrieved by the function. You can use the DataSet as a data source for
many OLE and ActiveX controls. In addition, you can use the DataSet with .NET Data
Provides to write the returned values to a database of your choice.
14.2.3.1 DataSets and XML Schemas
1) Right-click on the Project name in the Solution Explorer and select Add>Add New Item

2) Select DataSet and click Open. Then, click the XML tab at the bottom of the window and
enter the schema for your project into the text box.

The data types and relational structure of a DataSet are defined by an XML schema. You
must add a schema to your project before working with DataSets. To add a schema to your
project:
The following represents the schema you might generate for the XML string to be included in
the parameter to be supplied to the DataServerList function. This schema could be
used with the code sample included later in this section. You need to specify two schemas
when using DataSets, one for the parameter you will supply to the function, and one
for the parameter that will be retrieved by the function.
