Figure 1. Configure Data Flow. This WinForms test harness—a VB.NET project—runs under Windows XP Professional on a 667-MHz PIII client (OAKLEAF-XP1) with 384 MB RAM and a 60-GB Ultra-IDE drive. Checkboxes let you select sequential or random OrderID values and parameterized or nonparameterized T-SQL batch statements and stored procedures. This article's data uses random OrderID values with tables that contain data for an average 150,000 Orders and 400,000 Order Details records. In Web services mode, the GetDataSet operation becomes GetDiffGram and executes SQLXML 3.0 stored procedures that return nested, single DataSet objects.
