About the PowerBuilder ADO.NET
database interface
You can use the PowerBuilder ADO.NET database interface to connect
to a data source such as Adaptive Server® Enterprise, Oracle,
and Microsoft SQL Server, as well as to data sources exposed through
OLE DB and XML, in much the same way as you use the PowerBuilder ODBC
and OLE DB database interfaces.
Performance
You might experience better performance if you use a native
database interface. The primary purpose of the ADO.NET interface
is to support shared connections with other database constructs
such as the .NET DataGrid in Sybase DataWindow .NET.
